The engagement rate is a key metric in influencer marketing that measures how actively an audience interacts with content.

It is calculated based on interactions such as likes, comments, shares, or saves in relation to reach or follower count. This makes it a strong indicator of how engaged and interested the audience truly is – beyond just the number of followers.

A high engagement rate suggests that content resonates well and that there is a strong connection with the audience, which is why it is often considered more important than follower size alone.

For influencers, the engagement rate is a key indicator of content quality. For brands, it helps identify suitable partners and evaluate campaign performance more effectively.
