Enter 0 for any action you do not want to count. To average several posts, work out each one and take the mean, so that one big post does not hide the rest.
Frequently Asked Questions
How do I calculate engagement rate?
Add up the interactions and divide by followers or reach. 500 interactions is 5.00% of 10,000 followers and 12.50% of a reach of 4,000.
Should I use followers or reach?
Reach is usually fairer between posts, because a post few people saw is not marked down. By followers is easier to get for other people’s accounts, since reach is usually private.
Can engagement rate go above 100%?
Yes. One person can act several times, and people who do not follow you can engage. 120 interactions on a reach of 100 is 120%. It is rare, so check the figures if you see it.
