In this video, I am showing you how to solve the problem of adding and removing followers through the Twitter Follow and Unfollow functionality in Tweet Adder.
One thing that Tweet Adder does exceptionally well is give you the ability to do a Twitter Follow and Unfollow process that is either manual or automated.  One problem that people have when they use Twitter is that they can add people, but they don't know how to remove people in a time effective way.  This solves that problem.
The ability to add and remove followers is beneficial as it gives you the ability to automatically add and remove people from your Twitter account without spending any time doing it.  Tweet Adder allows you to build a super targeted list of potential Twitter followers and then automatically follow them.  On the flip side, it allows you the ability to remove anyone who is not following you so that your Following to Follower list doesn't get to large.
The automated Twitter Follow and Unfollow function in Tweet Adder saves me easily hours each week.
