Conversion Rate Filter

What it detects

Publishers generating fake or incentivized conversions often produce conversion rates that sit far outside what legitimate traffic delivers. A rate that is too high suggests fabricated conversions; a rate that is too low suggests click fraud inflating the denominator. The Conversion Rate Filter blocks conversions from any publisher or sub ID whose rate drifts outside your configured bounds.

How it works

Integr8 calculates the conversion rate for each publisher (and optionally each sub ID) over the selected time interval. When the rate falls below the minimum or exceeds the maximum threshold — and the minimum click and conversion counts are met — the filter rejects new conversions from that source and optionally blocks further clicks.

Evaluation runs continuously. A source that recovers within bounds during the next time window is unblocked automatically.

Configuration

Navigate to Fraud Prevention > Conversion Fraud > Conversion Rate Filter to configure this filter.

ParameterDefaultRangeDescription

block_clicksfalsetrue, falseBlock further clicks when threshold breached

The filter does not activate until both min_clicks and min_conversions are met. This prevents false positives on sources with low traffic volume.

What happens when triggered

When a publisher’s conversion rate exceeds the configured bounds:

  • Conversions from that source are rejected with a fraud_reason: cr_filter tag.
  • If block_clicks is enabled, further clicks from that publisher or sub ID are also blocked.
  • The block lifts automatically when the rate returns within bounds in the next evaluation window.

Review blocked sources in Reports > Conversion and Events Report using the fraud_reason filter.

Example

With low_cr: 1%, high_cr: 5%, min_clicks: 100, min_conversions: 2:

  • Publisher with 150 clicks, 1 conversion (0.67% CR) — conversions rejected (below minimum)
  • Publisher with 200 clicks, 12 conversions (6% CR) — conversions rejected (above maximum)
  • Publisher with 120 clicks, 3 conversions (2.5% CR) — passes the filter
