04 / Sample quality

Every response should earn its place.

Quality sample requires more than one fraud check. WDL evaluates identity, device, location, survey behavior and response quality throughout the respondent journey.

Verified People. Defensible Data.

Why sample quality matters

Risk rarely announces itself in one signal.

A respondent can pass a single check and still create risk elsewhere in the journey. Quality requires signals to be evaluated together, with context and review.

One quality standard

Multiple sources. One managed review path.

Direct audience access, owned recruitment and vetted partner supply enter a shared project-level quality and operational framework.

WDL Shield

Multi-Layer Sample Integrity Framework

Six connected checkpoints help identify risk before, during and after fieldwork.

01

Quality checkpoint

Identity

Establish signals that help validate who is entering the research process.

  • Participant validation
  • Repeat participant checks
  • Identity signals
02

Quality checkpoint

Device

Evaluate device-level patterns before they compromise response quality.

  • Device fingerprinting
  • Duplicate device detection
  • Suspicious device patterns
03

Quality checkpoint

Location

Compare declared and observed geography to identify location risk.

  • IP validation
  • Geo validation
  • VPN detection
  • Proxy detection
04

Quality checkpoint

Behavior

Read the respondent journey for patterns inconsistent with genuine engagement.

  • Speeding detection
  • Straightlining detection
  • Survey engagement analysis
  • Suspicious navigation behavior
05

Quality checkpoint

Response

Inspect the substance and consistency of submitted answers.

  • Open-end response checks
  • AI-generated response signals
  • Inconsistent answers
  • Low-quality response patterns
06

Quality checkpoint

Human Review

Apply experienced judgment where automated signals need context.

  • Manual quality review
  • Project-level review
  • Suspicious respondent investigation
  • Post-field quality review

Quality across the project lifecycle

Checks should inform operational decisions.

The six WDL Shield layers support decisions before, during and after fieldwork. No single check guarantees a risk-free response.

01

Before field

Set the project and supply approach before traffic starts.

  • Target review
  • Supplier selection
  • Survey link validation
  • Project setup
  • Soft-launch planning
02

During field

Review traffic, respondent signals and delivery as fieldwork progresses.

  • Traffic monitoring
  • Location / IP signals
  • Device duplication
  • Behavior indicators
  • Response-quality review
  • Quota / delivery monitoring
  • Supplier performance monitoring
03

After field

Reconcile delivery and carry findings into future sourcing decisions.

  • Final ID reconciliation
  • Quality review
  • Client issue review
  • Supplier performance review
  • Post-field investigation where appropriate

Quality philosophy

Verify the person.
Validate the device.
Understand the behavior.
Trust the response.
