Invalid traffic detection checklist in brief
Invalid traffic usually starts as a small drift in behavior, then compounds into budget waste. Detect it with repeatable checks, not ad-hoc alerts.
Who this is for
- Publisher operators with multi-source traffic.
- Advertisers managing approval-sensitive campaigns.
- Fraud teams needing operational checkpoints.
Definition
Invalid traffic detection combines behavior, identity, and payout consistency:
- unusual conversion shapes,
- suspicious retry or duplicate patterns,
- rejection reason concentration,
- latency spikes.
Decision table
| Signal | Likely outcome | Action |
|---|---|---|
| High duplicate-like patterns | Artificial activity | Activate stricter dedupe and source hold |
| Sudden reject concentration | Abuse or mismatch | Quarantine source and inspect payload |
| Volatile latency + conversions | Routing or provider instability | Reduce affected source caps |
| Normalized traffic but low value | Product-fit issue | Re-segment and retest objective mapping |
How it works
- Define threshold alerts for each signal.
- Validate signals against business context.
- Place source in hold/observe/scale bucket.
- Remove from scale pool until stability returns.
Checklist
- Set source-level invalid traffic score thresholds.
- Monitor duplicate and replay-like patterns.
- Compare reject reasons by source.
- Tie source holds to recovery criteria.
