Enhance fraud prevention with Adjust Conversion Rules | Adjust

Adjust's Conversion Rules address a critical gap in fraud prevention: fixed filters cannot account for business-specific requirements. The solution offers a configurable decision layer that validates traffic before attribution, using three rule types. Device-level rules control eligibility based on store validation (Google Play, Apple App Store), country, app/OS/SDK version, and device trust state.

Skip source rules prevent misconfigured campaigns from attributing traffic that doesn't match criteria (e.g., wrong region, version mismatch), automatically looking for the next eligible source. Post-install activity rules validate in-app events by source (SDK or S2S), timing, order, required parameters, revenue validation, region, version, and ad revenue signals. Key data points: store validation for major app stores, device trust states (trusted, unverified, untrusted), and event flow checks.

Actionable takeaways: ad ops teams can exclude deprecated app versions, block traffic from wrong regions, and catch automated or unrealistic event patterns in real time, without engineering involvement. This reduces wasted spend and ensures datasets are consistent across markets and app versions, moving fraud prevention from reactive audits to proactive ingestion control.
