Checklist: The QA pass that found a 9% silent leak

Checklist: The QA pass that found a 9% silent leak

A smartlink with 6 offers looked healthy on blended EPC. A scheduled QA pass found one offer 302-ing to a parked domain.

What we did:
☐ Step 1: Fire one synthetic click into each of the 6 offer slots.
☐ Step 2: Record final landing URL and HTTP status per slot.
☐ Step 3: Slot 4 resolved to a parked page (offer URL had expired) — held 9% weight.
☐ Step 4: Pull slot 4, redistribute its 9% to slots 1 and 2 by EPC.
☐ Step 5: Add the synthetic-click test to a daily cron.

Outcome: recovered 9% of traffic that was earning $0. Blended EPC rose from $0.25 to $0.28 (+12%) within 7 days.

Repeat daily: synthetic-click every live slot; a 200 status to the wrong domain is still a leak.
