Engagement rate measures how actively an audience interacts with content, expressed as a percentage of total followers or reach. It combines actions like likes, comments, shares, saves, and clicks, then divides by follower count or impressions depending on the formula used.
It’s one of the most useful metrics for evaluating content quality and audience connection - a small account with a high engagement rate often delivers more value than a large account with passive followers. Benchmarks vary by platform and niche, but anything above 3–5% is generally considered strong on most channels.
