Maybe you had not heard about Facebook having found bugs in its reporting tool, but surely as a Facebook page Admin, you had noticed some weird evolution in your insights lately… Well Facebook now reports that these bugs have been fixed, and they recommend you monitor your insights over a few weeks to see how it goes:
Here is the official article posted by Facebook:
Facebook Page Insights Reporting Update
As soon as we found the bugs, our engineering team began work to resolve them as quickly as possible. We’re rolling out fixes beginning this morning and over the weekend.
The actual impact of the bugs will vary from Page to Page and day to day based on a number of factors such as when and how frequently you post. To see the overall impact, if any, on your individual Pages, we recommend looking at your organic, paid and viral reach and impressions for your Page and for your posts over the next few weeks, starting on Monday, February 25. Because these bugs impacted our logging systems we won’t be able to backfill Page Insights with historical data.
Overall, we expect most Pages to see:
Total reach to stay the same or increase for most Pages
An increase in paid reach if you ran News Feed ads
An increase or decrease in organic reach, depending on many factors such as the composition of your fan base, when and how often you post and your spending patterns
A change in metrics computed from reach and impressions, such as engagement rate and virality
We appreciate your patience and we are committed to constantly improving and investing in the quality of Page Insights.
