Understanding Your Social Media Engagement Rate
Engagement rate is the ultimate metric for measuring how well your content resonates with your audience. Unlike "vanity metrics" like total follower count, engagement rate tells you if people are actually paying attention to what you post.
How is Engagement Rate Calculated?
The standard formula for social media engagement rate (ER) is the sum of all interactions divided by your total audience size, then multiplied by 100 to get a percentage.
ER = ((Likes + Comments + Shares + Saves) / Total Followers) x 100
While some marketers prefer using Reach (the number of unique people who saw the post) instead of Followers, the follower-based calculation remains the most common benchmark for public profile comparisons.
What is a Good Engagement Rate?
Benchmarks vary significantly across different platforms and industries. Here is a general guide for 2024:
Instagram: 1% to 3% is considered average. Anything above 5% is exceptional.
TikTok: High engagement is standard, often ranging from 4% to 10%.
LinkedIn: 2% is a solid benchmark for professional content.
Facebook: 0.1% to 0.5% is typical due to algorithmic restrictions on business pages.
