What counts as engagement

Definitions differ between tools, so this one is explicit.

10K to 100K — mid-tier1.5–3%Follower growth outpaces reach, so the percentage falls even as engagement rises.
100K to 1M — macro1–2%A large share of followers are inactive or never served the post.
Over 1M — mega0.7–1.5%At this size a 1% rate represents an enormous absolute audience.

This rate counts likes, comments, saves, shares against followers. Definitions differ between tools and platforms, so a rate is only comparable to another measured the same way — saves and shares in particular are often excluded, which lowers the figure.

Frequently asked questions

Practical notes about the inputs, assumptions, and result.

It depends almost entirely on your follower count, which is why a single threshold is misleading. Accounts under 1,000 followers typically see 3.5–6%; by 100,000 the usual range is 1–2%; above a million, 0.7–1.5% is normal. A 2% rate is unremarkable for a small account and excellent for a large one, and any tool that rates both against the same number is giving one of them the wrong answer.

Because reach does not keep pace with followers. Feed delivery is ranked, and a growing audience is a less uniformly interested one, so a shrinking share of followers ever sees a given post. Absolute engagement usually keeps rising while the percentage falls — which is why measuring against reach is often the more useful comparison over time.

For your own tracking, yes — saves in particular are a strong signal and are weighted heavily in feed ranking. But most published benchmarks were compiled from likes and comments only, so including saves lifts your figure above numbers it will be compared to. Both switches are here so you can measure it consistently, and the result states which definition it used.

Followers for comparing yourself to benchmarks and to other accounts, since that is what published figures use. Reach for judging whether a specific post landed, since it measures the people actually served it rather than the people who might have been. They answer different questions and are not interchangeable — a rate by reach is typically several times higher.

Because engagement is heavily skewed. One post that gets picked up by the algorithm can be ten times your typical post and drag the mean well above anything you normally see. The median tells you what a normal post does, which is the number to plan around. Where the two are far apart, the result says so.

Enough to cover a normal posting cycle — usually the last nine to twelve, excluding anything unusual like a giveaway or a collaboration. Fewer than five and one outlier dominates; more than a few months back and you are averaging across a different audience size.
