Outbrain Cross-Domain Tracking

Cross-Domain Tracking

Ensure identity persists when users move across domains, subdomains, or apps tied to Outbrain.

Use Cases & Risks

• Scenarios requiring cross-domain support such as checkout flows or microsites.
• Identity challenges introduced by third-party cookie loss or consent states.
• Attribution and reporting impact when configuration breaks.

Implementation Patterns

• URL decoration, first-party cookie strategies, or dedicated integrations provided by the platform.
• Coordination with developers or IT for domain allowlists, redirects, and shared authentication.
• Considerations for mobile app to web handoffs or hybrid experiences.

QA & Monitoring

• Test plans covering login flows, cart transfers, and multi-step journeys.
• Debug tools or logs to confirm identifiers persist end to end.
• Metrics to watch for leakage (drop-off, duplicate conversions, inflated sessions).

Governance & Change Control

• Documentation of approved domains, owners, and change windows.
• Process for adding or removing domains, including stakeholder approvals.
• Incident response workflow when cross-domain tracking degrades.
