Engagement rate
Engagement rate is the share of people who saw a post and then did something with it, such as like, comment, share or save it, written as a percentage.
Why it matters when you post for yourself
The formula: add up a post's engagements, divide by how many saw it, and multiply by 100. What counts as "saw it" changes the answer. Divide by reach and you get the share of people who engaged. Divide by impressions or views and you get engagements per showing. Divide by followers when you can't see reach, but that counts people who never saw the post.
Networks count engagements differently too. Instagram's Help Centre counts likes, comments, saves and shares as interactions. LinkedIn Help counts reactions, comments, saves, sends and reposts as engagements. Pick one formula and use it every time, so you're comparing your posts with each other.
Example
A post gets 40 likes, 6 comments and 4 shares: 50 engagements. It was shown 2,000 times. 50 divided by 2,000, times 100, is an engagement rate of 2.5% by impressions.
Where it shows up in Postmosis
Analytics in Postmosis works out each post's engagement rate as reactions, comments and shares divided by impressions, from the numbers you type in, and shows which formats and hooks do best for you. See the account audit

Common questions
Start my weekWhat is a good engagement rate?
It depends on the network, the formula and the size of the account, so one number would mislead you. Compare each post with your own last ten instead.
Should I use reach or followers?
Reach, when you can see it, because it only counts people who saw the post. Use followers when reach isn't shown, and note which one you used.
Do saves and shares count?
Yes, on most networks. Instagram counts saves and shares as interactions, and LinkedIn counts saves, sends and reposts as engagements.
