Engagement rate, explained: the formula and what's actually good
Engagement rate is the most quoted metric in creator marketing — and the most inconsistently calculated. Here's the standard formula, realistic benchmarks, and the traps to avoid.
The formula (and its variants)
The common formula: (likes + comments) ÷ followers × 100, averaged over the last 10–20 posts. Some tools add saves and shares when the data is available; some divide by reach or views instead of followers — which always produces a bigger-looking number.
When comparing creators, make sure you're comparing the same formula. An ER 'by reach' and an ER 'by followers' are different numbers wearing the same name.
What's a good rate?
Rough benchmarks by follower size on Instagram: nano accounts often see 3–7%, micro 2–4%, and rates decay naturally as audiences grow — a mega account at 1% can still be excellent. TikTok runs higher across the board; YouTube engagement is usually measured differently.
More useful than any benchmark: compare a creator to accounts of similar size in the same niche, not to the internet average.
When a high rate is a bad sign
Suspiciously high engagement can be bought. Watch for engagement pods (same accounts commenting on every post), emoji-only comment walls, and like counts that don't match comment quality. A fake-follower or quality check catches most of it.
The reverse trap: a low rate on a new account isn't automatically bad — check posting frequency and whether the niche simply engages quietly (B2B LinkedIn, for example).
Use it as a filter, not a verdict
Engagement rate belongs in your search filters as a floor — but the final call should weigh audience fit, content quality and past brand work. It screens out bad candidates; it doesn't pick winners.
