Since January 19th, and due to privacy rules enforced by Apple, Facebook has made changes to the attribution window settings in every account.
Changes in Facebook
The new default attribution window settings in your Facebook account should now be 7-day click and 1-day view, instead of 28-day click and 7-day view.
All your active campaigns will benefit from the new attribution setting automatically in your Facebook account. Inactive campaign will stay untouched.
On top of that, due to limitations around view-through signal, the attribution window settings for newly created campaigns will default to 7-day click only.
Finally, Facebook is deprecating three attribution window settings previously used: 28-day click, 28-day view, and 7-day view.
As Facebook stated it, "these changes won't impact ad delivery, but the new default attribution setting may result in a decrease in the number of reported conversions."
Changes in DashThis
When looking at your DashThis reports, all your conversion widgets will be impacted by the new changes.
The default attribution window for new Facebook Ads widgets will be aligned with the new settings: 7-day click and 1-day view, instead of 28-day click and 7-day view.
As for your existing Facebook Ads widgets, the attribution window will be changed only for the current period, and the previous 30 days.
If you wish to bring all your historical data back to the same default settings, you can manually refresh your widget.
As for the newly created campaigns defaulting to 7-day click attribution settings, these changes won't be reflected in DashThis as your widgets have no information on the creation date of your campaigns.
We will transition to the 7-day click attribution settings in the upcoming months.
Please note that this only affects widgets with conversion metrics.
