Differences between page views, reach, and impressions

When tracking the performance of social media pages, three metrics related to the number of people who have seen content are provided. We have defined the differences between the three metrics below: 

Page Views represent the total count of times a Page’s profile has been viewed, including views from both logged-in Facebook users and those who aren’t logged in. 

Reach refers to the estimated number of individuals who have seen any content related to your Page. 

Impressions indicate the total number of times any content associated with your Page has appeared on someone’s screen.
