Finding Twitter unfollowers can be a really hard task since Twitter doesn’t provide any data or notifications regarding unfollowers.
So where can you find who unfollowed you on Twitter?
FollowerAudit is a Twitter followers tracker tool which also lets you track your unfollowers.
It provides real-time updates whenever someone will unfollow you and a list of all the unfollowers. This will help you identify your unfollowers and track your followers growth rate.
