Twitter is a great tool to help you provide value for a targeted niche and build a following.
The problem is that Twitter has a limit on your Follower to Followers ratio.
Have you ever logged-in to your Twitter account and tried to follow someone to only see that dreaded message that says you can't follow anymore people at this time?
Well, I have found a great free tool to help you clean out your Twitter of old followers that aren't following you and also ones that are not really active.
It's simple and it works well

Click on the Sign-in with Twitter button and away you go!
Once you are finished you will now be able to follow more people in your niche that will potentially follow you back.
