Data Studio returning different results vs Facebook Ad Manager

I'm using Supermetrics to connect Data Studio to Facebook Ad Manager.


When I compare the "website registrations completed" returned by Data Studio, with the same metric shown in Facebook Ad Manager, they are significantly different. I'm assuming the metrics shown in Ad Manager are correct, and the ones in Google Data Studio are incorrect. 


Any ideas why this may be?

  • Hi Nick,

    Thanks for reaching out.

    Discrepancies in Facebook data are often caused by a difference in the attribution window used on Facebook side vs the one on Supermetrics report side. Please see Facebook Ads Discrepancies Due to Conversion Windows. Also, filters could cause issues Discrepancies in Data Studio When Using a Filter.
    Please let us know if you continue to experience the issue.  

    Best regards,
    Heidi / Supermetrics
  • Hi,


    I cannot see the numbers of my website registrations completed. It is 0 in all my campaigns and that is not what I see on my Fb Ads. Any idea why this could be?
