Migration name: Deprecate PTAT (People Talking About This)
Facebook will be removing the People Talking About This metric (PTAT) from Page Insights.
To better see how people interact with a pages content, the PTAT metrics have been split into separate elements: Page Likes, People Engaged (the number of unique people who have clicked on, liked, commented on, or shared your posts), Page tags and mentions, Page checkins and other interactions on a Page.
We recommend that you use these metrics moving forward to evaluate your Page posting strategy and engagement.
