Frequently Asked Questions
What is considered a good engagement rate on Instagram?↓
For accounts with 10k to 100k followers, an engagement rate between 2.0% and 3.5% is good, while rates above 4.0% are exceptional. Micro-influencers (under 10k followers) frequently achieve 5% to 8% engagement.
Why do engagement rates decrease as follower counts grow?↓
As accounts scale beyond 500,000 followers, content reaches wider, more passive audiences through algorithm suggestions, diluting the concentrated enthusiast engagement typical of smaller accounts.
Why are saves and shares heavily weighted by the Instagram algorithm?↓
Saves and shares indicate high evergreen value. The algorithm treats saves and shares as high-intent signals that the content is worth promoting across the Explore page.
How do brands use engagement rate to detect fake followers?↓
Accounts with hundreds of thousands of followers but engagement rates below 0.5% (with few genuine comments) are frequently bloated with purchased bot followers and offer poor return on sponsor ad spend.
