Facebook page insights will now more accurately count the number of impressions gained through fans sharing posts, according to a post on the Facebook Studio Blog.

Previously, impressions gained from initial shares were included in page’s total and viral impressions, but impressions from subsequent “shares of shares” were not.

Insights will now also include total impressions for all time. Previously, Facebook stopped collecting impressions data on posts after 28 days. These changes will give page owners a better sense of how their posts perform and what type of reach their messages receive.

Getting fans to share content is important for pages to gain a wider audience, but page owners couldn’t see just how many additional impressions they gained from those actions until now. Some page owners might not have even realized they were missing this data, but they will likely soon see greater numbers for total and viral impressions when they export page post insights.

According to the blog post, updated data will be available for page owners in the next few days. Last week Facebook changed the way check-ins were tallied on pages associated with a physical location, and at the end of February, the company announced a switch to real-time page insights.
