>=15% CTR on cross-sell surface among triggered users
Leading Indicators
- Cross-sell surface CTR
- Surface dismissal rate
- Trigger accuracy
Instructions
-
Run cross-sell-catalog-mapping drill to map product catalog to behavioral triggers using PostHog cohort comparison.
-
Pick the single highest-scoring product (trigger converts >=10% historically, >=50 users in cohort).
-
Run addon-discovery-surface-build drill for ONE product, ONE surface type (tooltip or banner).
-
Instrument PostHog events: addon_discovery_impression, addon_discovery_clicked, addon_activation_started, addon_activated.
-
Implement fatigue controls: suppress after 2 dismissals.
-
Human review: verify surface copy, placement, and PostHog events fire correctly.
-
Enable for 20-50 triggered users. Observe 5-7 days without changes.
-
Run threshold-engine drill: >=15% CTR on cross-sell surface among triggered users.
-
If PASS, proceed to Baseline. If FAIL, diagnose: CTR <5% = copy/placement wrong; 5-14% = refine surface type; dismissal >50% = tighten trigger.
