Why use reach instead of follower count?

Follower count includes inactive, ghost, or non-relevant followers who never see your posts. Reach only counts people who actually viewed the content, so the engagement rate is more meaningful as a content quality signal.

What counts as an interaction?

Likes, comments, shares, and saves all count as interactions. Some definitions also include link clicks or video views, but the core set is likes + comments + shares + saves. This tool lets you enter each separately so you can adjust based on the platform.

What is a good engagement rate by reach?

Above 3% is generally strong. Rates of 1–3% are average for most platforms. Below 1% suggests the content did not resonate with the audience that saw it. Instagram and TikTok typically see higher rates than LinkedIn or Twitter/X.

How is this different from engagement rate by followers?

Follower-based rate divides interactions by follower count. Reach-based rate divides by the number of people who actually saw the post. The reach-based rate is always equal to or higher than the follower-based rate, because reach is always less than or equal to follower count. It is a stricter and more accurate quality signal.

Where do I find post reach data?

On Instagram, go to the post insights and look for "Accounts Reached." On TikTok, check the video analytics for "Total Play Count" or "Reach." On Facebook, use the post-level insights. On LinkedIn, the metric is labeled "Impressions" (unique reach is not always available).

Can I use this for paid posts?

Yes. Reach-based engagement rate is especially relevant for paid content because you know exactly how many people the ad was served to. It is the standard metric used by media buyers to evaluate creative performance.
