Frequently asked questions
What is organic reach?
Organic reach is the number of unique accounts that see your post without paid promotion — driven by your engagement rate and the algorithm.
How is the estimate calculated?
We apply your engagement rate to your follower count for organic reach, then add an estimated 15% hashtag bonus on top.
Is this an exact number?
No. It is an estimate based on typical patterns. Your actual reach varies with content quality, posting time, and current algorithm behavior.
