One of the most effective ways I would recommend to grow Twitter Followers is to check out The TPTwitterStrategy, created by IBO member Terri Pattio. I use the Strategy and it worked for me even though I wasn't consistent. I was able to grow my Followers from 656 to over 2,000 in a matter of six weeks. And these are not just any followers but people who are likeminded and even Influencers. Here is a link to Terri's IBO Social Profile.
