Which to report

Engagement rate = engagements ÷ audience × 100. By-followers uses your follower count; by-reach uses accounts reached (more accurate, since not all followers see a post). "Good" varies by platform and follower count — smaller accounts usually see higher rates. General information only.

Two ways to measure engagement

Engagement rate is interactions divided by audience. Measured against followers, it's the common headline number; measured against reach (the accounts that actually saw the post), it's more honest, since organic reach is usually a fraction of your following. Report reach-based when you have the data.

Engagement rate = (likes + comments + shares + saves) ÷ audience × 100

Quick FAQ

What's a good engagement rate?

By followers, roughly: over 3% is strong, 1–3% is average, under 1% is low — but smaller accounts naturally run higher, and it varies a lot by platform.

Followers or reach?

Reach-based is more accurate because it reflects who saw the post. Followers-based is the common public benchmark since reach isn't always visible.
