What is unfollow?
An unfollow is when someone stops following an account on a social network, so that account's posts no longer appear in their feed.
Unfollows are a normal part of social media, but a sudden spike can signal a problem. It might mean you are posting too often, changing your topic or sharing content your audience does not want. Watching unfollow patterns helps you stay in tune with your followers.
On most networks, people can unfollow with a tap, and the account is not notified directly. Some networks also offer mute options, which hide posts without unfollowing. Analytics often show net follower growth, combining new follows and unfollows, so you may need to look closely to spot changes.
Do not take every unfollow personally; people's interests change. Look for patterns after specific posts or changes in schedule. Focus on serving the followers who stay. Avoid follow-for-follow schemes, which bring in people who will likely unfollow later.
Example
A fashion boutique noticed more unfollows after posting several sales posts a day, so it went back to a calmer schedule.
