Engagement Rate (ER)
Engagement Rate measures what share of impressions produced any engagement at all.
Divide engagements by impressions. That is Engagement Rate: when content was served, did anyone respond? It matters as your quickest comparison across posts and channels. Just know it weighs a drive-by like and a deliberate save the same.

Engagement Rate is the Engage phase entry read: quick, comparable, everywhere. Use it to open the analysis, never to close it. EQS says what the engagement meant. Engaged Reach says how many people were behind it.

Frequently Asked Questions
What is Engagement Rate?
Engagement Rate measures what share of impressions produced any engagement at all. It is the quick first read, built to start the analysis rather than finish it.
How do you calculate Engagement Rate?
Use the formula: Engagement Rate = (Total Engagements ÷ Total Impressions) × 100. Keep both inputs in the same reporting period and avoid mixing users, sessions, events, or customers unless the formula calls for it.
What data do you need for ER?
You need served impressions and engagements, pulled from the relevant connected sources and computed for the same period.
What mistakes should you avoid with ER?
The trap is treating all engagements as equal, which lets clickbait outscore substance. Also avoid comparing rates computed on impressions with rates computed on reach: same name, different maths.
When should marketers use ER?
Use Engagement Rate for fast comparisons across posts and channels, then decide nothing final on it. It flags what got a response. EQS and Engaged Reach tell you whether the response mattered.
What is a good ER?
Norms differ sharply by platform and format, so benchmark within each. Your own trailing average is the honest baseline, and beating it with quality intact is the goal.
