What is Social Post Engagement Rate?

Social post engagement rate is a key metric for measuring social content performance, calculating the proportion of post interactions (likes, comments, shares, etc.) to a specific base (reach, followers, or impressions). Different platforms and analysis tools may use different denominators. This calculator supports three common calculation methods, allowing comprehensive evaluation of post engagement performance.

Engagement Rate Calculation Formulas

Formula 1: By Reach

When you know post reach, calculate interaction proportion per reached person:

Engagement Rate = Total Engagements ÷ Reach × 100%
Example: 150 engagements ÷ 5,000 reach × 100% = 3.00%

Formula 2: By Followers

When evaluating follower participation level, use follower count as denominator:

Engagement Rate = Total Engagements ÷ Followers × 100%
Example: 150 engagements ÷ 10,000 followers × 100% = 1.50%

Formula 3: By Impressions (Optional)

When emphasizing impressions, calculate interaction proportion per impression:

Engagement Rate = Total Engagements ÷ Impressions × 100%
Example: 150 engagements ÷ 8,000 impressions × 100% = 1.88%

Frequently Asked Questions

What is a good engagement rate?

Good engagement rate depends on platform, industry, and follower scale. Generally, Facebook page average engagement rate ~0.5-2%, Instagram ~1-5%, LinkedIn ~2-5%. More followers typically means lower engagement rate. Key is tracking your own historical data and continuously optimizing.

What's the difference between reach, followers, and impressions for calculating engagement rate?

Recommend selecting appropriate denominator based on analysis purpose, or reference multiple calculation methods simultaneously.

How to increase social post engagement rate?

Can increase engagement rate through: (1) Publishing high-quality, valuable content; (2) Using attractive visual materials or videos; (3) Asking questions or prompting comments in posts; (4) Posting during follower active times; (5) Responding to follower comments, building interaction relationships; (6) Using stories, polls and other interactive features.

Why do I have many followers but low engagement rate?

High follower count but low engagement may be due to: (1) Poor follower source quality (like bought followers, lottery-attracted imprecise audience); (2) Content doesn't match follower expectations; (3) Posting frequency too high or too low; (4) Algorithm restrictions reducing reach rate; (5) Follower interest shifted or account inactive. Recommend reviewing content strategy and follower quality.
