shows how much people interact with the content. Factors that influence engagement include users’ comments, shares, likes, and more. This is an important metric to keep an eye on because higher engagement is a sign of great content.
Engagement = Shares + Likes + CommentsEngagement Rate
is a metric that is used heavily in analyzing social media. Because the engagement rate is calculated relative to the number of followers a company has on social media (or number of views), the rate for both small and large companies can be compared equally.
Engagement Rate = (Shares + Likes + Comments) / ReachReach
is the number of people who received impressions of a Page post. Reach might be less than impressions since one person can see multiple impressions. For example, if a person sees a Page update in News Feed and then sees that same update when a friend shares it that would represent a reach count of one.
