How to Calculate Engagement Rate per Impression

Engagement rate per impression is a vital social media metric that measures the level of interaction your content receives relative to the number of times it was displayed on a screen. Unlike "reach" (which counts unique users), "impressions" count every single time the content is viewed, making this metric a strict test of content quality and "scroll-stopping" ability.

The Formula

(Total Engagements ÷ Total Impressions) × 100 = Engagement Rate (%)

Example Calculation

Imagine you posted an infographic on LinkedIn. Over the course of a week, the platform reports the following data:

• Total Engagements: 250 (Likes: 180, Comments: 40, Shares: 30)
• Total Impressions: 10,000

Using the formula:

(250 / 10,000) = 0.025

0.025 × 100 = 2.5%

In this scenario, your engagement rate per impression is 2.5%.

Why Measure Impressions Instead of Reach?

While reach measures how many unique people saw your post, impressions measure frequency. If one person sees your post three times and likes it once, your Engagement Rate per Reach would be 100%, but your Engagement Rate per Impression would be 33.3%. Calculating by impressions provides a more conservative and realistic view of how effectively your content captures attention every single time it appears in a feed.

What is a Good Engagement Rate per Impression?

Benchmarks vary significantly by industry and platform, but generally:

Rate Range	Performance Level
Below 1%	Low – Needs improvement in hook or creative.
1% to 3.5%	Average – Standard performance for most brands.
Above 3.5%	High – Content is resonating deeply with the audience.
