Data quality & trust

Trust you can measure.

Reach means nothing if the people behind the responses aren't real. Quality is our first deliverable — screened at the door, monitored throughout, and reported, never assumed.

ISO 20252:2019ISO/IEC 27001:2022ISO 9001:2015ESOMAR Corporate MemberGDPR & DPDP aligned

Every respondent screened before they reach your survey — and monitored throughout it.

The foundation

Four things every project stands on.

Authentic, verified respondents

Real, unique people — identity-checked, deduplicated and fraud-screened before a single answer is recorded.

Owned & governed panel

Bigfoot Surveys is our own recruited, profiled and rewarded community — so we can stand behind who's in it and how quality is maintained.

Methodologically sound

Certified processes (ISO 20252), rigorous questionnaire QA and correct weighting — quality is built into the method, not bolted on after.

Measured, not assumed

Quality is reported, not promised. Removals are logged and documented so you can see exactly what was screened and why.

The fraud-prevention stack

Two layers, no gaps.

We stop fraud at the door and catch it mid-stream. Both layers run on every project — and respondents are never told why they were removed, so the checks can't be gamed.

Before the survey

Pre-survey screening

Caught at the door, before your link ever loads.

  • Identity verification & digital fingerprinting
  • Cross-source deduplication
  • Bot & automation detection
  • Fraud suppression / no-fly list
  • Geo & VPN / proxy checks
  • Duplicate-device screening
During the survey

In-survey monitoring

Continuous checks throughout fieldwork, not a one-off.

  • Attention & trap questions
  • Speeding & straight-lining detection
  • Open-end coherence (AI-assisted)
  • Response-pattern & grid checks
  • Consistency & logic validation
  • Continuous in-field monitoring

An owned, governed panel

Bigfoot Surveys is our own recruited and profiled community. Owning the source means we control the two things that matter most — who is in the panel, and how their quality is maintained over time. No black-box supply, no guesswork.

The trust layer: TrustedMR

We built TrustedMR — a platform that scores trust across the market-research industry, from supplier reliability to fraud screening. We hold ourselves to the same standard we built for everyone else, which is why quality here isn't a claim; it's infrastructure.
