Tracking issues account for more "campaign failures" than actual campaign failures
When a Pinterest campaign looks like it's underperforming, the first question is always: is the tracking correct? If your checkout event isn't firing on the right page, or your attribution window is set to 1-day instead of 30-day, your ROAS appears catastrophically low while your actual sales are fine.
This guide walks through every tracking issue we've encountered across 343+ projects — in the order they're most likely to be the problem.
