Engagement Rate is a fundamental social media and content marketing metric used to measure the level of interaction your audience has with your content. It tracks actions such as likes, comments, shares, saves, and clicks, comparing those actions against your total follower count or the total reach of the post.
A high engagement rate indicates that your content resonates strongly with your audience, which prompts social media algorithms to show your content to even more people. In modern marketing, engagement rate is considered a far more valuable metric than sheer follower count, as it proves you have an active, attentive audience rather than passive 'ghost' followers.
