Our read: fixing a 9-second postback delay recovered 18% of 'lost' conversions
A pop buyer's tracker showed ROI 18% worse than the advertiser's own dashboard. Same clicks, different conversion counts.
They traced it: server-side postbacks were firing 9s late on average, and their optimizer was cutting zones before conversions landed — killing winners as 'losers.'
— moved postbacks to a queued real-time fire
— attribution gap closed to under 2%
— 18% of conversions that were being ignored reappeared
The traffic was always profitable. The plumbing was lying to the optimizer.
— confidence: high
