Check your follower list manually and compare it with an earlier saved list
Use the platform’s built-in follower analytics if available
Review recent notifications for unfollow activity if the app provides them
Use a trusted third-party follower-tracking app only if it is safe and allowed by the platform
Export or screenshot your follower list regularly to compare changes over time
Look for sudden drops in follower count after posting or profile changes
Ask mutual followers if they still see the account in their following list
Check whether the person blocked you or deactivated their account instead of unfollowing you
