Engagement rate (ER) is interactions divided by audience size — likes, comments, and sometimes shares relative to followers or views. There's no universal formula; the number only means something once you know which one produced it. ## What the term actually covers ER = (interactions ÷ denominator) × 100. Interactions are usually likes + comments, sometimes + shares or saves. Denominator is followers (follower-based ER) or views (view-based ER) — different questions, not interchangeable. Social Fetch has no single ER endpoint. Profile and post lookups return raw counts; you compute the ratio client-side with the formula that fits your comparison. ## A worked example 500 likes, 40 comments, 10 shares, 10,000 followers → (550 ÷ 10,000) × 100 = 5.5% follower-based ER. Same post, 50,000 views → (550 ÷ 50,000) × 100 = 1.1% view-based ER. Quote the formula or the number is meaningless across comparisons. ## How it's used in practice Most uses are relative: trend over last N posts, vs a niche peer, vs account baseline. Keep formula and platform fixed. From Social Fetch: profile lookup for followers, recent posts/videos for interaction counts, apply your formula and average across a window. ## Engagement rate vs raw reach and impressions ER is a ratio; reach and impressions are counts. High reach + low ER is common (wide distribution, weak response). Follower count alone doesn't show engagement quality. ## Common mistakes Comparing ER across platforms as one metric — different interaction types and norms. Using one post's ER as the account average — average over recent posts instead. Quoting ER without stating formula, denominator, and window. ## What it is not Not a pre-computed Social Fetch field — derived from raw metrics the API returns. Not content quality, reach, or growth by itself — one ratio at one point in time. ## FAQ ### How is engagement rate calculated? Interactions ÷ denominator × 100. Denominator is followers or views/impressions — not comparable across formulas. ### What's a good engagement rate on TikTok? No universal benchmark — depends on formula, niche, and follower size. Compare within platform and formula. ### Does Social Fetch have an engagement rate endpoint? No dedicated ER endpoint. Raw likes, comments, shares, views, and followers — compute client-side. ### Why do engagement rate numbers differ between tools? Different formulas: followers vs views, which interactions count. Both can be correct for their definition. ### Is follower-based or view-based engagement rate better? Different questions — audience fraction vs viewers who engaged. Pick one and stay consistent. ### Can I compute engagement rate from the Social Fetch API? Yes — profile + recent posts/videos, formula client-side. Ask can pull the underlying counts. ### Why does engagement rate drop as follower count grows? Larger denominator plus audience dilution and algorithmic reach — common pattern, not always a problem. ### What counts as an 'engagement' — do views or saves count? Views are usually the denominator, not numerator. Saves sometimes in numerator where exposed; likes, comments, shares most common. ## Related - [Average TikTok engagement rate](https://www.socialfetch.dev/data/average-tiktok-engagement-rate) - [Average Instagram engagement rate](https://www.socialfetch.dev/data/average-instagram-engagement-rate) - [TikTok engagement rate tool](https://www.socialfetch.dev/tools/tiktok-engagement-rate) - [Instagram engagement rate tool](https://www.socialfetch.dev/tools/instagram-engagement-rate) - [TikTok platform](https://www.socialfetch.dev/platforms/tiktok) - [Instagram platform](https://www.socialfetch.dev/platforms/instagram) - [Ask](https://www.socialfetch.dev/ask) - [Unified schema](https://www.socialfetch.dev/glossary/unified-schema)
