Facebook Engagements are a sum of reactions, comments, and shares attributed to an article.
Here's a quick example of how these engagements can be counted and attributed.
When a Facebook user shares a link to your article on their timeline, that counts as one (1) engagement.
If that post generates ten (10) likes, six (6) comments, and then gets shared eight (8) more times, the original link will have received 25 total engagements (1 + 10 + 6 + 8 = 25).
To see the full reaction breakdown, simply hover over the Facebook Engagements number.
