How long after someone sees or clicks your ad you can still credit them for a conversion. A 7-day click window means if someone clicks your ad today and converts within the next week, that conversion gets attributed to your ad. 1-day view attributes a conversion to an ad if it was viewed within 24 hours of the conversion.
Common attribution windows:
- 1-day click
- 7-day click (most common)
- 7-day click, 1-day view
- 28-day click (less common post-iOS 14.5)
