Hi fellas! I'm currently trying to optimize my Instagram accounts performance by getting rid of these followers who don't interact with my content (ghost followers). So far, I've found two (free!) tools to do so : Likemeter and Non-abonnés. Likemeter doesn't seem to work well, so I've decided to use Non-abooné. This is an android app but I don't know its English-speaking markets name, sorry about that). It took around two minutes to analyze a 3K followers account in order to get basic informations about my followers such as who is following me back or who I ain't following back. Then, it took around one more minute to analyze my last 20 publications in order to know who these ghost followers are. Once the useless followers found, the tool provides you very cool informations in order to choose what actions to complete and which accounts to target. For example, Non-abonnés shows me how many interactions theses ghost followers have completed on my content (likes and comments). It also lets me know if I'm already following these ghost followers or not. This tool seems to work well but there's no automation feature, so I have to unfollow manually a couple of hundreds of followers... Yeah, I know, that kinda sucks... Feel free to give this tool a try or share your feedback about a different platform!
