Attribution Setting
Attribution Window and Conversion Window are merged under Attribution Setting.
On January 19, Facebook merged the account level attribution window and the ad set level conversion window into a new ad set level attribution setting that can be accessed during campaign creation Optimization & Delivery.
You will have Attribution Setting at the ad set level.
The new default will be 7 days after clicks.
The view window will not be available anymore.
The newly supported windows are:
- 1-day click
- 7-day click (default after iOS 14 prompt enforcement)
- 1-day click and 1-day view
- 7-day click and 1-day view (initial default, implemented on January 19)
Once iOS 14 changes are enforced, the view window will not be available. Only conversions result after clicks will be reported. The new default will be 7 days after a click.
The old Attribution Window
Attribution Window is the time Facebook looks for conversions starting when the ad is delivered. This affects how ad results are reported.
In the past, default windows were 28 days for clicks and 7 days for views.
It means that if someone clicked on an ad and performed the desired action in the next 28 days, this was considered a conversion.
If someone just saw the ad without clicking and performed the desired action in the next 7 days, this was considered a conversion.
Various other Attribution Windows were supported.
The old Conversion Window
Conversion Window is used for ad delivery optimization. In the past, this was different from Attribution Window and it was available at ad set level.
Impact
It’s possible to see decreased results for your ads. Since the time to measure conversion is shorter, the reported numbers can be lower. This will not necessarily result in fewer real conversions.
