The engagement rate formula
Engagement rate by impressions = (reactions + comments + reposts + clicks) ÷ impressions × 100. That’s the one LinkedIn’s own analytics is closest to, and the fairest way to compare posts.
Engagement rate by followers swaps impressions for your follower count. It’s handy when you don’t have impressions, or to compare yourself with someone else’s public numbers.
Tip: Comments are worth more than reactions. A comment takes effort and starts a conversation that keeps the post alive. The calculator shows them on their own for that reason.
