Attribution window

A click-through window credits conversions that follow a click. A view-through window credits conversions by people who saw the ad without clicking. Longer windows credit more conversions to the ad, so the same campaign can show a different CPA depending on the window chosen.

ChatGPT ads offer click windows of 7, 14 or 30 days (30 by default) and a view-through window of 0 or 1 day (1 by default). OpenAI’s sources disagree on how views are counted: its Reporting page says API conversion counts include view-through conversions since 2026-09-30, while its Measurement Pixel page says the Ads Manager Conversions column stays click-through only.

Gravity currently counts conversions within 7 days of a Gravity click or view and says the window may change. Its FAQ calls attribution click-based, which conflicts with the reporting docs.

Before comparing channels, line up their windows: a 30-day click window on ChatGPT and a 7-day click-or-view window on Gravity measure different things, and adding them together can count some conversions twice. Use the same window across your own analysis where the channel allows a choice, and note which surface a figure came from, since API and dashboard counts can differ. Admux reports show channel results side by side with a previous-period comparison, which is useful for trends; treat cross-channel CPA comparisons with care until the windows match.
