How to fix attribution setting discrepancies in Facebook Ads data

Facebook made a broad set of changes to attribution settings following Apple's iOS 14 update in early 2021. Some of the changes have the potential to cause discrepancies when reporting Facebook Ads data in Supermetrics. 


These errors occur at the query level in Supermetrics. To remove the discrepancies, every affected query should be individually updated. Use the instructions below to find the specific steps for your impacted query.


Queries using attribution setting

If your Supermetrics query has a conversion window that doesn’t match the attribution setting you see in Facebook Ad Manager, your conversion results won't align.


Solution 1: Check that your attribution settings align

If the attribution setting in your query doesn’t match the one you see in Facebook Ad Manager, a discrepancy can result. 


To fix this:

  • Check which attribution setting you’re using in the impacted query and in Facebook Ads Manager. If they’re different, adjust them so they match.
  • If your Ad sets/Campaigns have multiple attribution settings, reset your attribution setting to Default.



Solution 2: Check your default attribution setting

If your Ad set has the same attribution setting as your query and the discrepancy is still there, reset the attribution setting in your query to Default.


If you don’t see Default as an option, your instance of the Facebook Ads data source might be out of date. To fix this, add a new Facebook Ads data source. Remember to rename the old one before you do this, so you don’t have two Facebook Ads data sources with the same name.


Queries using “On impression date”

Following Facebook’s iOS 14 updates, the “On impression date” option for the Report time of action stats setting will only work for data older than April 26, 2021. 


When pulling data newer than that date, use “On conversion date” instead.


For data ranges covering this date — beginning before it and ending after it — no working settings can typically be selected. Create queries in parts instead, showing the division.


Queries using custom conversions

Discrepancies can come from using incorrect conversion windows, or from custom conversion window settings. Learn more about this feature and how to troubleshoot it.


Queries using inline attribution metrics, including Outbound clicks and Video watch %

If you’re finding discrepancies between your reported Facebook Ads "Outbound click" or "Video watch %" data and the data that you see in Supermetrics, making an adjustment to your attribution settings can help resolve the issue.


This problem, and its solution, continue to evolve as Facebook adjusts to changes it made following the iOS 14 update in early 2021. 


Solution: Set the conversion window to “default”

A conversion window defines the period of time during which a logged conversion occurs. Often, resetting this field to “default” can help to remove discrepancies.

SKAdNetwork campaigns

SKAdNetwork campaigns use an attribution setting that Apple provides. They can't be adjusted, so for this campaign type it’s important to have the conversion window setting be "Default (7 d click)". If this setting isn’t chosen, the conversion data will come back as zero.


If you have mixed campaigns — SKAdNetwork and non-SKAdNetwork in the same account — consider filtering for those to ensure the settings align: 


Is Campaign using SKAdNetwork EQUALS true
