Reach is especially useful when paired with engagement rate, impressions, click-through rate, and conversion rate.

Reach formula

Frequently asked questions

What is social media reach?

Reach is the number of unique people who saw your social media content. If one person sees the same post multiple times, they usually count as one reached user.

How do you calculate reach rate?

Divide people reached by total audience size, then multiply by 100. For example, 5,000 people reached from 20,000 followers equals a 25% reach rate.

What is the difference between reach and impressions?

Reach measures unique people. Impressions measure total times content was displayed. Impressions are usually equal to or higher than reach.

What is a good reach rate?

A good reach rate depends on the platform, account size, content type, niche, and whether the content is organic or paid. As a general estimate, 25% to 50% is strong, while 50% or more is very high.
