SOP: Fix a postback gap that hid your best offer

SOP: Fix a postback gap that hid your best offer

An offer showed $0.06 EPC and was nearly killed. The smartlink's S2S postback was dropping 40% of conversions — the offer was actually fine.

Steps run:
— Step 1: Compare advertiser dashboard conversions vs smartlink-recorded: 100 vs 60.
— Step 2: Trace the postback — click_id was truncated at 32 chars; advertiser sent 36.
— Step 3: Widen the click_id field and re-test with a manual conversion.
— Step 4: Recalculate EPC on corrected data.

Outcome: that offer's true EPC was $0.10, not $0.06 — top-3 in the smartlink, not a kill candidate. Across the whole smartlink, recovered attribution lifted reported blended EPC from $0.21 to $0.27.

Repeat weekly: reconcile advertiser-side vs smartlink-side conversion counts; a gap over 5% is an attribution bug, not a bad offer.
