Post-bid Verification
Brand safety and viewability measurement that runs after an ad has already won the auction and served, reporting on what happened rather than preventing it.
Definition
Brand safety and viewability measurement that runs after an ad has already won the auction and served, reporting on what happened rather than preventing it.
Why it matters
Post-bid doesn't stop bad spend from happening, it measures it after the fact, which is what most makegood and reconciliation claims are built on. Confusing this with pre-bid is a common junior mistake that leads to assuming a verification tag is protecting spend in real time when it's actually only reporting on it after the money's already gone.
Key consideration
Post-bid does not stop bad spend, it measures it after the fact — most makegood and reconciliation claims are built on post-bid data, not pre-bid.
