Discrepancies between Facebook Ads reporting and third party reporting
can be usually be attributed to one of the following:
Differing statistics or methodologies
Facebook Ads reports clicks. Many third party reporting packages report
visits or page views, which may not correspond directly to clicks.
Additionally, some third party reporting packages require that the
user's browser have cookies, Javascript, and/or images enabled in order
to record statistics, which may result in undercounting relative to the
clicks reported by Facebook Ads. Statistics measured at daily intervals
may be based on different time zones. For more information, please also
consult the documentation for your third party reporting package.

Incorrectly implemented third-party reporting Please ensure that you
have implemented your third-party tracking correctly. We strongly
recommend installing multiple statistics packages and comparing them to
each other (as well as Facebook Ads reporting) to get a more complete
picture of site traffic. Two free, commonly available packages are
Slimstat (
SlimStat — A simple web stats analyser based on ShortStat - Wettone.com) and Google Analytics
(
www.google.com/analytics).
Facebook Ads click quality measures
We have measures in place to reduce click fraud and may filter out some
clicks and impressions. This may result in third party packages
overcounting relative to the clicks reported by Facebook Ads.
We take reporting accuracy seriously and have several measures in place
to ensure that you are billed accurately, including regular tests of the
system from an advertiser's perspective.
If you still feel there is an issue, feel free to follow up with us.
Please note that Facebook does not endorse or otherwise support any of
the third-party products or pages linked to in this email.
