Have a functioning Facebook page, and I plan to start running paid ads on it in the coming days.

But before I proceed I will like to have a clear knowledge of the difference between engagement and clicks cos in the common sense I feel engagement should lead to click, but sometimes I get many times higher clicks than engagement in a post and this has left me totally confused.

Someone should please enlighten me.

Your post engagements will equal the total of your post Likes, post comments, and post shares

The key here is "posts." Your campaign results aren't only reporting on the Likes happening on your post directly, but also Likes that happen on other posts as a result of seeing your ad. This is meant to give you a bigger picture idea of what kinds of actions people are taking after they see your ad
