The respondent experience (the industry increasingly says participant experience) is everything a person goes through to take part in a market research survey: being chosen for it, being checked, being screened, answering, and being paid, or not. The term usually gets narrowed to the questionnaire: make it shorter, make it work on a phone, write better questions. But by the time a respondent sees the first question, most of their experience has already happened, in systems the questionnaire's author never sees.

I take a lot of surveys myself. It is the fastest way I know to see what this industry does to the people it depends on. In a normal week I get screened out after three minutes of profiling questions, or promised ten minutes and given twenty. Sometimes I am removed by a check I never see.

I spent five years on the supply side before starting Enlightn. The map below is the one I wish someone had handed me back then: one picture of the whole journey, with real numbers. Buyers, suppliers and panelists rarely look at the same thing when they talk about the respondent experience. A clear map is where improving it starts. Below it: where the experience suffers, stage by stage, a roadmap for improving it, in order, and where Enlightn fits.

The respondent journey, mapped end to end

Left to right: everyone a study touches, from the offer they click to the complete that gets paid, and every outcome in between, drawn at the same scale. The volumes are the Global Data Quality benchmark's (Wave 2, H1 2026: 46 companies, 13 countries, about 1.8 million survey records), joined into one journey, with a few estimates marked as such. Click any band to read what happens there, what the map simplifies, and what the person experiences. The whole map is also on this page as text, band by band.

The supply side is simplified: one supplier with two termination gates, quality checks first, then a pre-screen. Real studies run several suppliers at once, and a supplier is not always the origin of the respondent: it may buy from an aggregator, which buys from an exchange, which buys river traffic. Every band that flattens something like that is marked and carries the note in the panel. Which volumes are the benchmark's and which are estimates: about the numbers.

Vocabulary: we aligned the names of the bands as much as possible with the Global Data Quality glossary, the industry's best shared vocabulary for participant quality. Where it has no term yet (complete, terminate, over-quota, partial, or anything about the depth of a supply chain), we use the words the industry uses. Which volumes are the benchmark's and which are estimates: about the numbers.

Still in the study Did not qualify / no room Started, never finished Removed by a quality control Delivered — counted and paid Simplified

1,363 people were put in front of this study. 261 finished with a complete that counted: one paid complete for every 5.2 journeys started. 37.3% of the people who started the survey were turned away for fit or for room. Bands marked are simplified; click one for the note.

Where the respondent experience suffers, stage by stage

Every band on the map is something a person lived through. The teal is the outcome they signed up for: a survey they qualified for, finished, and got paid for. Every other color is an outcome they did not expect when they clicked, and each one is a worse experience. None of these bands can go to zero. The job is to shrink them without giving up the quality the study needs at the end. This section walks them in journey order, with pay last because it runs through all of them: what the person lives through, the fix, who can act, and why it usually does not happen. The journey numbers are the benchmark-based scenario above; the participant-side evidence is measured, from our survey of 300 active online panelists.

The invitation: routed by earnings per click

Most of the 1,363 people at the left edge of the map were not invited to this study. They clicked on an offer: a survey of a stated length, for a stated reward, in a panel app or on a rewards site. A router then sent them wherever the expected earnings per click were highest, on whatever it knew about them, which is usually a handful of basic socio-demographic answers, collected once from a question library that has not been reworked or improved in years. Many pass through several routers in a row, from a panel to an aggregator to an exchange to the study, and those routers do not share data. So the person answers the same age, gender and household questions again at every hop, before any survey has started. The map draws that as one supplier and one gate; the note on the first band says what it hides. From the supplier's own seat, the benchmark puts actual incidence at 45.9%: more than half of the people it screens for a study do not fit. That is what routing on earnings per click looks like from the inside.

The fix. Route on what is already known, and carry it across hops. A router that knows a person's profile can send them only where they are likely to qualify, and a chain that passes the answers down does not ask them again. Where the match is uncertain, say so in the offer rather than promising a reward the person has a coin-flip chance of earning.

Who can act. Supplier owns the routing objective and the profile data it runs on. Structure: routers belong to different companies, and none of them is paid to share what it knows with the next.

Why it rarely happens. Earnings per click is a good objective for the router and a bad one for the person: it is maximized by sending everyone everywhere and letting the screeners sort it out. It is also a volume game. Suppliers compete against each other on the same studies, and the one that sends more traffic faster fills the quota, so nobody wants to be the router that sends fewer, better-matched people and watches the study fill through someone else. And sharing profile data across hops means trusting the next company with your asset.

Pre-survey checks: judged by systems that do not agree

Before the first question, a person usually passes through more than one fraud and quality check: the supplier's, then, when the buyer hosts the questionnaire, a second set at the survey link, sometimes a third from an aggregator in between. Sometimes there is none at all: in the benchmark, 5% of suppliers and 12% of research agencies record no pre-survey controls, and just over half of the agencies rely entirely on their supplier's. Where the checks exist, they do not return the same verdict. Each runs its own rules at its own thresholds, and a device or a network that passes one fails the next. When several suppliers feed the same study, the same person can also arrive twice, through two of them, and only the survey side can see that duplicate. In this scenario 22% of the people routed at the study are rejected by a quality system before they see it: 305 of 1,363, with nothing to read and nothing to appeal. Add the supplier's pre-screen, the next section, and 36% never see the survey at all. The honest ones caught by mistake are false positives, what the Global Data Quality glossary describes as "incorrectly validated participants identified as of poor quality", and nobody in the chain measures how many there are.

The fix. One verdict, made where the signals are, by someone paid to get it right. The supplier has the most signals: it can verify identity, it holds the login history of the account and of the IP address, and it sees the person across many studies, not one session. It also has the least reason to use them. An account it removes is revenue it stops earning, and a fraudster is profitable right up to the moment they cash out. So the verdict needs a party paid for precision rather than for throughput, and it needs to travel with the person: one verdict instead of three that disagree, and a reason attached to a rejection instead of silence.

Who can act. Supplier runs the richest checks and holds the history. Buyer adds the second gate, and decides whether to trust the first.

Why it rarely happens. Trust. Buyers add their own gate because the supplier is paid per complete, its thresholds are set with that in mind, and nobody can audit them. So each side controls what it can, the checks stack, and the discrepancies land on the person. A high catch rate reads as diligence to everyone upstream, so no one is paid to ask how many of the caught were honest.

Screen-outs and over-quota: rejected on criteria nobody passed along

Answer profiling questions you have answered a hundred times, then read "unfortunately, you do not qualify" three minutes in, unpaid and unexplained. In this scenario 31% of survey starts end that way, 37% once over-quota is added. Everyone in that band had already passed a pre-screen upstream, where the supplier had turned away many more on the same criteria. The over-quota is a cousin of the screen-out: the person qualified, and the cell they fit was already full, closed mid-session, or throttled. From the inside it is the same dead end and the same zero. In our panelist survey, disqualification is the frustration named most, at 63%, ahead of surveys running long and ahead of low pay itself, and it compounds with pay: the share of panelists who feel underpaid falls from 74% among those who finish 3 or fewer surveys out of 10, to 23% among those who finish 8 or more. Same rewards. The difference is how often the journey ends in a rejection.

“I will get almost to the end of the survey, and then it will kick me out and say that I didn't match.”

Verbatim, Enlightn survey of 300 active online panelists, 2026

Repeat that enough and the person adapts. Screened out three times on the same questions, they learn what the screener wants, and the fourth time they qualify with a profile that is not theirs. In B2B it is the decision-maker answer that opens every survey. The industry files this under overclaiming and treats it as fraud. Most of it is a genuine person doing what the journey taught them, and the quality check that removes them ten minutes later is punishing a lesson the screener gave. That is the direct line from respondent experience to data quality: every screen-out teaches, and part of what the red bands remove further down the map was taught here.

Most of the band comes from the supplier not having the criteria. Either the system cannot carry them, because the structured targeting fields a router can use are a fraction of what a screener asks, or the buyer does not share them, out of fear that the supplier builds a leading pre-screener that teaches people the right answers. So the supplier knows the study's incidence and rarely knows why it is not 100%. There is no feedback loop either: it sees that its respondents were terminated, not which question terminated them.

The fix. Pass the criteria down, and pass the reason back. A supplier that knows which criterion fails can stop sending the people who fail it, and a person who is only asked what nobody knows yet gets a shorter screener and a better chance. Make the promise the most burned participants actually want: among panelists who flag disqualification as their top frustration, 35% pick "you'll likely qualify" as the single most important promise a panel could make, versus 18% of everyone else. Panelists themselves draw the line to data quality: asked what would most improve the quality of their own answers, "fewer screen-outs / better targeting" came second (50%) only to higher pay. For over-quota, pace the cells and close them before the click rather than after. Where a terminate still happens, pay something for the time. Panelists describe the fix in almost the same words a sample provider would:

“a more intelligent routing system that matches surveys with the right professionals from the start. Respecting our time by providing high quality.”

Verbatim, Enlightn survey of 300 active online panelists, 2026

Who can act. Buyer decides what criteria to share, whether a terminate reason travels back, and how quotas are designed. Supplier holds the profile data, applies the criteria it is given, and paces the invitations.

Why it rarely happens. Profiling data deep enough to spare people the screener is hard to maintain: it has to be structured, kept current, and mapped to the criteria a study actually uses, and few suppliers have invested in it. Sharing criteria means trusting the supplier not to game them, and returning terminate reasons is work nobody is paid for. Pacing costs speed, and speed is what buyers pay for.

Partials: the promised ten minutes

Told ten minutes, given twenty-five. A 40-row grid on a phone. A session that breaks at question 30 and pays nothing. In the benchmark the abandon rate is 10.5% of records for research agencies and 16.8% for suppliers: the same people, counted from two doors. And the map splits each partial band into two populations most disposition systems cannot separate: true drop-offs, which are a decision, and technical failures, which are not.

The fix. Design surveys you would enjoy taking yourself: if you would not sit through that grid on your phone, neither will they. State the real length and honor it, design for the phone the sample actually arrives on, and instrument the survey so drop-off and breakage separate: one is a questionnaire-design problem, the other an engineering bug that nobody hunts because it hides inside a metric named after respondent behavior.

Who can act. Buyer, almost entirely: the length, the grid, the device mix, and, when it hosts the survey, the instrumentation that splits the two populations.

Why it rarely happens. Questionnaire length is a negotiation between stakeholders who each add one more question, and none of them is present at minute 22 of the respondent's session. An honest length estimate costs nothing. It is simply nobody's KPI.

Quality checks: rules built for fraud, applied to humans

Three of the red bands are quality checks judging a person's answers: in the screener, mid-questionnaire, and after completion, when a review the person never sees removes the complete and sometimes reverses the reward. In the benchmark, research agencies remove 15.3% of records in-survey and 8.9% of finished completes afterwards; on B2B studies the after-the-fact figure is 59.6%. The tools were built for fraud, and fraud is real. But they are applied to humans, and humans are inattentive sometimes, contradict themselves sometimes, and misread a question that was badly written. A check that 40% of a sample fails is not proof that the sample is bad. It is a poorly designed check, or a poorly designed survey. An incoherence can reflect the complexity of real behavior as easily as a bad respondent.

The fix. Build quality checks that a genuine but imperfect human passes. Fire them early, so a problem costs a click rather than a paid session. Calibrate them on a known-good subsample before fieldwork, and read a high failure rate as a signal about the check before reading it as a signal about the people. Where a removal happens after completion, keep the reward unless there is actual fraud, and say why. Genuine panelists deserve a fair hearing, and so does the data: a rule that removes the attentive person who disagreed with the grid is removing signal.

Who can act. Buyer writes and calibrates the checks, decides whether a judgment call costs the participant their reward, and owes the supplier the exact reason behind every reconciliation. Supplier needs that feedback loop to do its part: a panelist who repeatedly terminates for quality across studies should be removed from the panel, and that is only possible if the reasons come back.

Why it rarely happens. A quality check's false positives cost the buyer nothing; the error lands entirely on the participant. Removing more reads as rigor in a deliverable, and no one measures precision because there is no gold standard to check against. Every incentive points toward judging late and harshly; the participant's side of that trade is not in anyone's ledger.

Pay, across the whole journey: the anchor has drifted

Pay is not a stage; it is the thing every stage spends. Ask 300 active panelists what a fair reward for a 10-minute survey would be, and the median answer is $1.25, about $7.50 an hour. Nearly half named a dollar or less. That is not what fair pay is; it is what the people who stayed have adapted to calling fair. 57% still feel underpaid, and they are still there, completing surveys. Underpayment doesn't show up as exit. It shows up inside the data, as attention nobody is paying for.

“Don't take the participants for granted. The better I'm treated/compensated, the better effort/higher quality my responses will be.”

Verbatim, Enlightn survey of 300 active online panelists, 2026

The fix. Price the time honestly on the studies that need engaged humans, keep rewards predictable, and pay something for terminates. Those are the improvements that reopen the pool to the people the current rate keeps out.

Who can act. Structure. The reward is what is left of the buyer's CPI after every layer's margin; no single party can raise it alone without pricing itself out.

Why it rarely happens. The CPI is set upstream by buyer budgets. A supplier that raises rewards alone prices itself out of any marketplace sorted on price. And because no buyer can verify quality at the point of purchase, quality never earns the premium that could fund the pay. So the reward settles at the lowest level the pool tolerates, which quietly selects the pool.

What shrinking the bands buys: an ecosystem the good actors stay in

Every band that is not teal makes the experience a little more adversarial, and the people it drives out are not the ones we would choose to lose. A genuine panelist who is screened out three times in a row, promised ten minutes and given twenty, or removed after finishing, draws the obvious conclusion and leaves. The bad actors do not leave. They adapt: they learn which screener answers get them through, they rush the questionnaire to maximize what they earn per hour, they run several accounts. The experience we collectively offer today is arguably hardest on the good actors and easiest on the people it was meant to keep out. In our panelist survey, fair pay and "you'll likely qualify" together account for 71% of the promises panelists most want a panel to keep; those are the two bands a person feels most directly.

Why this one pays for itself. Shrink the bands and the people who stay in the ecosystem are the ones who came for the right reasons. They do not have to be re-recruited, re-verified or re-screened, every study deepens what is known about them, and the data at the end needs fewer filters because less garbage went in. The reason it stays rare is structural: the benefit accrues to whoever keeps the participant relationship, and in a layered chain most of the parties spending a respondent's goodwill do not own it.

The pattern across all six bands is the same one. Each fix is rational for the system and irrational for every actor alone, because respondent time is paid only when it ends in a complete: every other outcome is free to the buyer and to the supplier, and costly to the person. That is why respondent-experience initiatives that stop at questionnaire polish don't move the bands. They shrink in the structure, upstream of the design.

A roadmap for improving the respondent experience, in order

The end goal is to fix everything before the click. Every check, screener and review after it is a filter applied to a defective structure: garbage in, garbage out. So the order matters. Transparency comes first because nothing below it happens between parties that cannot see each other, and pay comes last because raising CPIs while the experience is still bad, and the model still runs on volume rather than on accurate targeting, only pays more for the same thing. This is the sequence we think the industry should work through, with what each step asks of buyers and suppliers, and what it unlocks for the next. A working roadmap, not a finished one.

Supplier Step 1 · start here

More transparency from suppliers

Buyers cannot trust what they cannot see, and today they see very little of the left half of the map. Nothing below this step happens between parties that cannot see each other, which is why it comes first.

  • What you do to ensure quality: which checks run, at which stage, on which signals.
  • Why you drove a given panelist to a given opportunity: the profile data and the logic behind the routing decision.
  • Whether you aggregated or outsourced to external providers, and what share of the study came from each.
  • What was routed and removed upstream, per study, so a buyer's incidence and removal rates can be read against the whole chain. Which numbers each side can compute today is on the fieldwork-metrics page.

The reason to do it is not goodwill. A premium for quality cannot exist for quality nobody can verify, so disclosure is what lets a supplier charge more for the panelists it protects, instead of losing money for doing the right thing.

What it unlocks. The left half of the map stops being a black box. Buyers can share criteria with a supplier they can see, which is what step 2 needs, and step 4 becomes possible.

Buyer Supplier Step 2

Improve incidence rates

Being screened out is the reason high-quality panelists leave the ecosystem, so it is the first thing that transparency should buy, and it needs both sides.

  • Buyers: share more about the exact target. The criteria the screener actually uses, passed down the chain once rather than a fraction of them re-interpreted at every hop. Return the reason when a respondent is terminated, so the supplier learns why its incidence is not 100%.
  • Suppliers: spend more time profiling panelists, and pair them with the right opportunity. Real, recent profile data instead of a question library that has not changed in years, and routing on fit rather than on earnings per click alone.
  • Both: pace the cells, so a qualified person is not turned away because the room filled while they were answering.
  • Both: pay something for a terminate while incidence is being fixed, so a rejection stops being a zero.

What it unlocks. Fewer rejections per click, the single change panelists ask for most, and a pool that stops selecting for the people who tolerate being rejected.

Buyer Step 3

Step up on survey design and honest length

Once the right people arrive, the survey itself is the next place the experience is lost, and it is entirely the buyer's to fix.

  • Design surveys you would enjoy taking yourself. If you would not sit through that grid on your phone, neither will they.
  • Estimate the length accurately and fairly: on a phone, on the final questionnaire, and put that number in the offer.
  • Split drop-offs from broken sessions when you host, so the questionnaire problem and the engineering problem each get their own fix.

What it unlocks. Partials fall, and the people who qualified finish: the most expensive band to lose becomes the easiest to keep.

Buyer Supplier Step 4

Fairer quality checks, for everyone

With the transparency from step 1, buyers can stop stacking their own gates on top of the supplier's out of skepticism, and both sides can build checks that a genuine but imperfect human passes.

  • One verdict, carried with the person, instead of three that disagree.
  • Fire checks early, so a problem costs a click rather than a paid session.
  • Read a high failure rate as a signal about the check before reading it as a signal about the people.
  • Keep the reward on judgment calls, reverse it only for actual fraud, and tell the person why.

What it unlocks. Fewer honest people removed by mistake, and less of the data thrown away with them.

Everyone Step 5

Raise CPIs, and widen who takes surveys

Once the experience is worth the time, pay for the time, and not before: a higher CPI paid into blind routing and a bad experience buys the same volume from the same people at a higher price. Today the reward settles at the lowest level the remaining pool tolerates, and that pool is a narrow slice of the population.

  • Price the time on the studies that need engaged humans, and keep rewards predictable.
  • Bring back the people who left, or never joined, because ten minutes of their attention was worth more than a dollar to them.

What it unlocks. A respondent base that looks like the population rather than like the people who tolerate the current deal, and data that buyers stop having to defend.

Where Enlightn fits: a trusted third party to accelerate the roadmap

Every step above is structural, and none of them happens without trust. Buyers add gates because they cannot see what suppliers do; suppliers hold back on profiling because nobody pays them for it; both keep the criteria and the reasons to themselves. Someone in the middle has to be trusted by both sides. That is the role Enlightn plays.

For suppliers, we take on the profiling and the verification. Their panelists answer open-ended, AI-assisted questions once, with explicit consent, and pass a quality layer before they enter the pool. The supplier is paid for that, a fee per profiled panelist, and paid again with a premium on every complete when one of its high-quality panelists is activated on a study. Nothing changes in its routing: activation runs through the recontact flow it already has.

For buyers, we send only people we already know: profiled, quality-checked and matched to the study before any invitation goes out, so what arrives at the questionnaire is qualified twice over, on quality and on fit. The quote, before fieldwork, shows who we would recontact and why. The fieldwork analysis, after it, reports incidence, disqualification, completion and drop-off against what the quote committed, per source. Never anonymous traffic, and nothing blended without the buyer seeing it.

On the studies run so far, disqualification has averaged 43% lower than benchmark traffic on the same screener. A small number of studies, with one supplier so far, but these are the first steps of the roadmap, measured. If you have a live brief on your desk, . Within 24 hours you get your quote, free: who we would recontact, why they match, and how many completes we are confident about per target. Feasibility answered before you commit to anything.

The respondent journey, band by band

The full reference behind the map: every band in journey order: what happens there, what the map deliberately simplifies, and what the person on the receiving end experiences. It is the same content the map's side panel shows when you click a band. Counts are the benchmark-based scenario above (1,363 routed, 1,000 at the link). Band names follow the Global Data Quality glossary wherever it has a term. The metrics each band feeds are on the fieldwork-metrics page.

Clicked an offer, routed to this study

1,363

1,363 people, the whole scenario · 100% of those who started the journey

Everyone the supplier put in front of this study: panelists who clicked an offer (a stated length, a stated reward) and were sent here by a router choosing the destination with the highest expected earnings per click, or who received an invitation for this study specifically. Either way they reached the supplier's own screening layer, and most of them see a few pre-screening questions there, to pre-check their eligibility and their quality before the survey. This is where the map starts, and it is already a long way downstream of the person deciding whether to answer a survey at all.

What happened before this (how the panel was recruited, who was invited, who never opened the invitation) is out of scope here. It matters, and it is invisible to everyone downstream of the panel that owns it.

What this map simplifies

One supplier, one source. A real study usually runs several suppliers at once, and a supplier is not always the origin of the respondent: it may buy from an aggregator, which buys from an exchange, which buys river traffic. Each of those layers can terminate a respondent for fraud or for fit, on its own rules, and none of it is reported upward. Read this single band as a tree that can be three or four levels deep, whose shape nobody downstream is shown. ESOMAR 37 asks a provider to name its sources and the share of each precisely because the answer usually stops at the layer that provider buys from. For the full picture of who sits between a panelist and a survey, the GDQ / MRS presentation of the sampling ecosystem is the best public map.
What the person experiencesAn offer: "12 minutes, $1.10", in an app, an email, or a "surveys available" tile. Then, often, a few pre-screening questions. They do not see the router behind the offer, how thin the data it decided on was, or how many hops they are about to be passed through, each one asking their age again.

Rejected by the supplier's quality checks

173

173 people · 12.7% of the 1,363 who started the journey

Terminated by the supplier's own pre-survey quality layer before the survey existed to them: duplicate entries, technical fraud (anti-detect browsers, proxies and VPNs, automation), known fraudsters on blocklists, failed quality traps inside the pre-screener, and hyperactive accounts answering implausible volumes of surveys. Suppliers often rely on an external fraud-detection provider for the technical signals, with a proprietary layer or score of their own on top.

Branches in this scenario

  • Duplicate — same person, second entry50
  • Technical fraud detected70
    • Anti-detect browser18
    • Proxies / VPNs22
    • Automation / bots21
    • Known fraudster on a blocklist9
  • Failed quality checks at pre-screening questions35
  • Hyperactive participants18

What this map simplifies

One set of checks. With several suppliers, and sources beneath them, there are several independent fraud systems in the chain, each with its own thresholds, its own vendor, and its own unmeasured false-positive rate. That is why one supplier's stated fraud rate is not comparable to another's: they are measuring different traffic, at different thresholds, after different upstream filtering. When the supplier also hosts the questionnaire, this is the journey's only pre-survey gate: there is no second check at a link, because there is no link.
What the person experiencesUsually nothing they can read. The session ends before it begins: a "no surveys available right now", a redirect back to the dashboard, sometimes an account flagged without notice. An honest person caught here as a false positive is never told, and has nothing to appeal.

Rejected by the supplier's pre-screen

190

190 people · 13.9% of the 1,363 who started the journey

Qualified as a person, terminated as a fit: pre-screened against the buyer's targeting criteria, through pre-screening questions that often collect new answers or ask again for information the supplier already holds, or turned away because the supplier's own allocation for this study was already full.

What this map simplifies

One pre-screen. In a layered chain a respondent can be pre-screened two or three times, against copies of the targeting criteria that were passed down and re-interpreted at each hop, on stored profile data of different ages and quality. That is enough on its own to explain why two suppliers report different incidence on the same study: no dishonesty required, and no way for the buyer to see it.
What the person experiencesA few profiling questions they have answered many times before, then "you do not qualify", or nothing at all if the pre-screen ran silently on stored data. Unpaid, unexplained, and for a survey they never saw.

Arrive at the survey link

1,000

1,000 people · 73.4% of the 1,363 who started the journey

Everyone who cleared the supplier's checks, qualified on whatever pre-screeners it ran, and arrived at the survey link. It is the only number both sides can really agree on.

Everything to the left of this node happened in systems with no shared identifier, no shared status vocabulary, and no obligation to report. Everything to the right is the survey side's to instrument.

What this map simplifies

One stream of entrants. With several suppliers on a study, the same person can arrive through two of them, often because the same panel sits underneath both. Nobody upstream can catch that duplicate, because neither supplier knows the other is in the study. Only the survey side can, and only if it looks.
What the person experiencesA page loads. From here on, at least, the survey exists. For the person this looks like the beginning; it is already the second half of the journey.

Rejected by the survey's own quality checks

132

132 people · 13.2% of the 1,000 who reached the link

Entrants terminated by the survey side's own pre-survey quality layer, before the first question, usually a third-party fraud-detection tool plugged into the link: duplicates, including the same person arriving through two suppliers, technical fraud, blocklisted and hyperactive accounts. These checks run after the supplier's, on different signals and thresholds, so the band is where the two systems disagree, not a verdict on either.

Branches in this scenario

  • Duplicate — same person, second entry58
    • Across suppliers34
    • Within one supplier24
  • Technical fraud detected55
    • Anti-detect browser14
    • Proxies / VPNs18
    • Automation / bots15
    • Known fraudster on a blocklist8
  • Hyperactive participants19

What this map simplifies

The duplicate split is the point. With several suppliers on a study, the normal case, a meaningful share of duplicates is the same person arriving through two of them, often because the same panel sits under both. No supplier can catch that one: neither knows the other is in the study. Only the survey side can, and only if it looks. When the supplier hosts the questionnaire, this gate does not exist: its checks run once, at its own door.
What the person experiencesRejected a second time by a system checking the same things the supplier checked a minute earlier: device, IP, history. To the person it is indistinguishable from a screen-out: same dead end, no reason given.

Start the survey

868

868 people · 86.8% of the 1,000 who reached the link

Everyone who sees the first question of the survey. The standard denominator for completion rate. It is not always tracked properly: where it is not, entrants at the link are used in its place.

What the person experiencesThe survey they were promised finally begins, often after several rounds of pre-screening questions and routers whose names they never saw.

Removed in the screener by a quality check

110

110 people · 11.0% of the 1,000 who reached the link

Removed by a quality check on the answers while still inside the screener: speeding, contradicting stored profile data, failing a red herring, tripping a low-incidence trap set for people who qualify for everything. Built mostly to catch respondents who misrepresent themselves to qualify.

What the person experiencesTerminated a few questions in, sometimes for answering too fast, sometimes for tripping a trap they did not know was there. The message says "thank you", and the reward does not arrive.

Screened out: no profile match

269

269 people · 26.9% of the 1,000 who reached the link

Started the screener and did not qualify: the answers do not match the target profile. This is the terminate the participant experiences as being thrown out.

What this map simplifies

This population was already screened once. Everyone in this band survived the supplier's pre-screen, so the study's screen-out rate is measured on traffic somebody else already filtered against a copy of the same criteria. In a layered chain it may have been filtered two or three times, by systems using stored profile data of different ages. That is enough on its own to explain why two suppliers report different incidence on the same study.
What the person experiencesThe most familiar rejection in the industry: three minutes of profiling questions, then "unfortunately you do not qualify". In our panelist survey it is the frustration named most often, at 63%. Everyone in this band was already pre-screened for this same study, upstream.

Over-quota: qualified, but no room

55

55 people · 5.5% of the 1,000 who reached the link

Qualified, but the cell they belong to was already filled, closed mid-session, or throttled by pace controls.

What the person experiencesNothing was wrong. They were exactly who the study wanted, and the room was full. From the inside it feels like a screen-out: same dead end, same zero. And the person learns nothing about why.

Leave, or lose the session, in the screener

45

45 people · 4.5% of the 1,000 who reached the link

Started the screener and never reached its end. Two different populations share this band: true drop-offs, which are a decision, and technical failures: broken sessions, incompatible devices, lost redirects. Most disposition systems cannot tell them apart, because in both cases the respondent simply stops sending signals.

Branches in this scenario

  • True drop-off30
  • Technical failure15
What the person experiencesEither a decision (the screener ran long, asked something they did not want to answer) or a broken session they never chose. Both end the same way: silence, no reward, and a study that counts them as a drop-out.

Qualify

389

389 people · 38.9% of the 1,000 who reached the link

Passed the screener, inside a quota with room, now answering the main questionnaire.

Buyers and suppliers rarely track this point directly, and it is the one input the strict incidence formula needs, which is why reports fall back on completes instead. Tracking it also gives partials a meaning: someone who leaves before this point most likely felt they would not qualify; someone who leaves after it genuinely disliked the experience.

What the person experiencesThe first good news of the journey: they are in. Sometimes the survey tells them so; often it does not, and the questionnaire simply continues. What is ahead is what they were promised ten minutes for.

Removed mid-survey by a quality check

43

43 people · 4.3% of the 1,000 who reached the link

Qualified, then removed mid-questionnaire by a quality check on the answers: speeding, straight-lining a grid, a failed open end, a trap question. Respondents usually have to fail more than one check before they are terminated.

It is done mid-survey rather than after so that the supplier does not pay an incentive to someone the buyer would reconcile later.

What the person experiencesRemoved mid-questionnaire, often without knowing which behavior triggered it. Ten minutes in, the session ends and the reward with it.

Leave, or lose the session, mid-survey

60

60 people · 6.0% of the 1,000 who reached the link

Qualified, started the main questionnaire, and never reached the end. The same two populations as in the screener: true drop-offs, which are a decision, and technical failures.

Branches in this scenario

  • True drop-off41
  • Technical failure19
What the person experiencesTold ten minutes, given twenty-five. A forty-row grid on a phone. Or a session that breaks at question 30 through no fault of theirs. Either way: qualified, gave real time, paid nothing.

Reach the last page

286

286 people · 28.6% of the 1,000 who reached the link

Reached the last page. Counted as a complete by the survey platform and, usually, already paid by whichever panel in the chain owns the participant. Not yet judged: the split into good and bad quality happens next.

Not everyone in this band answered the survey. Some people find the exit redirect, the URL that marks a session as complete, and call it directly: the supplier's system records a complete that the survey data does not contain. The industry calls that a ghost complete.

What the person experiencesThe end page, then a redirect back to where the session came from. Relief, and a reward that is usually credited now, before anyone has decided whether the answers count.

Removed after the work as bad quality

25

25 people · 2.5% of the 1,000 who reached the link

Completes judged bad quality on review and removed before delivery: gibberish or AI-written open ends, straight-lined grids, internal contradictions, in-survey duplicates surfacing in the data file.

What the person experiencesFinish the whole questionnaire, then be removed by a review they never see. Sometimes the reward is reversed, rarely with a reason, never with an appeal. For an honest participant caught on the wrong side of the call, the whole session was for nothing.

Delivered: counted, and paid

261

261 people · 26.1% of the 1,000 who reached the link

What is delivered as good quality: the completes that raised no flag at all, and the ones that raised a flag but were kept after review. Keeping a flagged complete is a judgment call, and the size of that flagged-and-kept share is worth knowing.

Branches in this scenario

  • No quality flag raised244
  • Flag raised — kept after review17

What this map simplifies

One more step when the supplier hosts. When the supplier hosts the questionnaire, one more step follows this band: the client accepts the file, or reconciles (rejects) part of it, and a reconciled complete can cost the person a reward that was already credited.
What the person experiencesThe journey worked: their time was paid for and their answers are being used. This is the only band the person can be sure of, and the one that decides whether they come back.

Respondent experience: questions research teams ask

Short answers, each drawn from the sections above.

What is the respondent experience in market research?

Everything a person goes through to take part in a survey: clicking an offer and being routed to a study, being checked for fraud and duplicates, being pre-screened against the study's targeting criteria, arriving at the survey, being screened again, qualifying or being screened out or over-quota, answering the questionnaire, having the answers reviewed after the fact, and being paid or not. Most of it happens before the first question, in systems the questionnaire's author never sees. The map on this page is the full version.

Why does the respondent experience matter for data quality?

Because it selects who stays in the pool. A genuine panelist who is screened out repeatedly, given twice the promised length, or removed after finishing leaves; the people who adapt to that experience, by learning the screener answers and rushing to maximize what they earn per hour, stay. Panelists say so themselves: asked what would most improve the quality of their own answers, "fewer screen-outs / better targeting" came second (50%) only to higher pay in our survey of 300 active panelists. Quality checks after the fact are filters on a defective structure: garbage in, garbage out.

Why are survey incidence rates so low?

Because most people reach a study through a router that decides on earnings per click and a handful of basic socio-demographic answers, not on the criteria the screener will actually apply. Suppliers rarely receive those criteria in full, either because routers can only carry a fraction of them as structured data or because buyers withhold them for fear of leading pre-screeners, and they get no feedback on which question terminated their respondents. In the Global Data Quality benchmark (Wave 2, 2026), research agencies see an actual incidence of 59.1% and suppliers 45.9%, both below what was sold (62.0% and 53.6%).

What does a router do in survey sampling?

A router is the system that decides which survey a panelist is sent to after they click an offer. The Global Data Quality glossary defines it as "technology that redirects participants to specific surveys". In practice most routers choose the destination with the highest expected earnings per click, on whatever profile data they hold, and a panelist often passes through several routers in a row (panel, aggregator, exchange) that do not share data, answering the same profiling questions at each hop.

Who is responsible for the respondent experience, the buyer or the supplier?

Both, at different stages. The supplier owns the routing decision and the profile data behind it, the pre-survey checks, and the pace of invitations. The buyer owns which criteria it shares, the screener and the questionnaire, the stated length, the quality checks and whether a judgment call costs the participant their reward. The reward itself is set by the whole chain: what is left of the buyer's CPI after every layer's margin. The roadmap on this page assigns each step to its owner.

Is the participant experience the same thing as the respondent experience?

Yes. The industry is shifting from "respondent" to "participant" (the Global Data Quality glossary and ESOMAR use participant), but both describe the same journey: everything a person goes through to take part in a study, from the offer they click to the payout. This page uses respondent because it is still the term most people search for.

How do you improve the respondent experience?

In order, and before the click wherever possible. First, suppliers become transparent about their quality checks, their routing decisions and their sourcing, because nothing else happens between parties that cannot see each other. Second, improve incidence rates: buyers share more about the exact target and return terminate reasons, suppliers profile their panelists properly and pair them with the right opportunity, and a terminate is paid something while that is being fixed. Third, buyers step up on survey design and honest length estimates. Fourth, that transparency allows fairer quality checks for everyone, with less skepticism on the buyer's side. Fifth, once the experience is worth the time, raise CPIs to bring back the people who do not take surveys today because it does not pay enough. The roadmap details each step.

About the numbers, and sources

About the numbers. The volumes are one scenario built on the Global Data Quality Benchmarking report, Wave 2 (H1 2026; data collected October 2025 to March 2026 from 46 companies in 13 countries, about 1.8 million survey records, 87% of them general consumer studies). The survey half uses the research-agency cut, per 1,000 records at the link: 13.2% removed before the first question, 15.3% removed in-survey (11.6% of it for fraud), 10.5% abandoned, 59.1% actual incidence, 8.9% removed after completion. The supplier half uses the supplier cut: 12.7% removed by its own quality checks, and an actual incidence of 45.9%. That incidence is computed over everything the supplier sees, including the survey's own screen-outs redirected back to it, which is how suppliers report it. Both seats therefore count the same 389 qualified people, and the gap between 59.1% and 45.9% is what sizes the supplier's pre-screen: about 190 terminates per 1,000 people who reach the link. That is an estimate, not a benchmark figure; if suppliers counted only their own pre-screen terminates, it would be larger, not smaller. The two cuts come from different companies' records, not from the same studies; the map joins them as if they were one study, which is the main liberty taken. Four things the benchmark does not report are estimated: over-quota (set at 6.3% of starts), how quality removals and partials split between screener and questionnaire, every sub-branch split (duplicates, technical fraud, hyperactivity, drop-off vs technical failure), and reconciliation. The supply side is drawn as one supplier with two termination gates, a deliberate simplification marked on every band it affects. What no band can show is what every check missed: that share is real, sits inside the delivered completes, and can only be sized with a validation study on a known-good subsample. The same scenario, seen from the buyer's and the supplier's side, is on the fieldwork-metrics page.

Band names follow the Global Data Quality glossary wherever it has a term; where it has none (complete, terminate, over-quota, partial, the depth of a supply chain), the words are the industry's. Disposition and status vocabulary otherwise follows the Cint Exchange respondent-journey documentation and the PureSpectrum supplier status codes, the two most complete public disposition-code lists. Supply-chain vocabulary follows the ESOMAR 37 questions on sample sources, source transparency, and blend. Participant-side evidence is from Enlightn's survey of 300 active online panelists (2026). Method, caveats and full numbers are in the write-up. The pilot comparison (disqualification averaged 43% lower than benchmark traffic) is observational, on the same studies and screeners, across a small number of studies with one supplier; not a randomized trial.
