What Is Engagement Rate on LinkedIn?
Engagement rate is a social media metric that expresses interactions with a post, such as reactions, comments, shares and clicks, as a percentage of the people who saw it, usually measured by impressions. It lets you compare posts that reached audiences of different sizes on a like-for-like basis.

Engagement rate, explained
Engagement rate answers a narrow question: of the people who saw this post, how many did something with it? The usual calculation divides total interactions by impressions and multiplies by 100, though tools differ on which interactions they count and whether they use impressions or followers as the base, so compare numbers only within one tool. It is useful for spotting which topics, formats and hooks hold attention with your audience, and for noticing when a change in your writing or the feed is affecting how people respond. Its limits are just as important. A post can have a high engagement rate from people who will never buy, and a quiet post can start the one conversation that becomes a customer. For founder-led content, treat engagement rate as a diagnostic and pair it with business measures: qualified conversations started, meetings booked and pipeline created per post.
Example
A post seen 4,000 times with 120 reactions, comments and shares has an engagement rate of 3%. A post seen 1,000 times with 50 interactions has 5%, even though it reached fewer people.
In practice
Comments usually say more than reactions, because they cost the reader more effort and open a conversation. The LinkedIn ROI guide lays out a scorecard that starts from conversations rather than engagement rate.
