I have never done twitter before and I read a lot of threads on how to get followers. My goal is to build 1 legit twitter account that would drive traffic to my site. I know I need to follow the followers of popular accounts in my niche. I have an old account (over a year old) but I don't know if I can change it's name. I can also create a new account. My question is: how many people can I follow with new account and with an old account/day. And even more important: how many and when do I unfollow people? I have read that if you unfollow only people not following back then your account will get banned. But if I follow people following me back then they might unfollow me also. How can I keep a ratio of more people following me than I am following? I hope somebody can answer these questions (mostly about unfollowing).
