Engagement rate
The share of an audience that interacts with content — engagements divided by reach, followers, or impressions. The core measure of organic and influencer performance.
Engagement rate is the proportion of an audience that interacts with content — likes, comments, shares, saves — divided by a chosen base such as reach, followers, or impressions. It is the core health metric for organic social and influencer content.
Why it matters for agencies
The denominator changes the story: engagement-on-reach rewards content that travels, while engagement-on-followers measures audience quality. State the basis before you benchmark. When vetting creators, engagement rate is a sharper signal of real influence than follower count, which is easily inflated.
