# Post View Attribution

> Crediting a conversion to an ad the user only saw (an impression) but never clicked — a model AnyTrack does not use, because AnyTrack attribution is click-only.

Post-view attribution credits a [conversion](/glossary/conversion) to an ad the user only **saw** — an impression — but never clicked. It is an industry-standard model used by ad platforms like Meta (which defaults to a 1-day view window). AnyTrack does **not** use it: AnyTrack [attribution](/glossary/attribution) is click-only, so only actual clicks are ever counted.

## Post View Attribution vs Post Click Attribution

- [Post Click Attribution](/glossary/post-click-attribution) — credits an ad the user **clicked**. Post-view credits an ad the user merely **saw**. AnyTrack does post-click and not post-view, which is a deliberate design choice, not a limitation.

## How post-view attribution relates to AnyTrack

Because AnyTrack ignores views and the ad platforms count them, AnyTrack and Meta will report different numbers — expected behavior, not an error. The platform credits impressions inside its own network using its own modeling; AnyTrack credits clicks across every channel using first-party data and [UTM parameters](/glossary/utm-parameter). If you need a view-based number, read it in the ad platform's own reporting; if you need one click-based number across all channels, read it in AnyTrack. See the [Conversion Attribution Matrix](/docs/conversion-attribution-matrix) for the side-by-side.
