1. Follow everyone who follows you. It might seem counter-intuitive to do this when you're focused ongaining followers, but it's a good practice because:
• People who notice that you didn't follow them back might unfollow you. • When you follow back, some people might respond to you publicly, which will give you some added exposure to their followers.[3] If you're worried that you won't be able to keep up with that many people, you're right. Once you're following over 100 people, it'll be pretty much impossible to read all their updates. You'll become more selective in who/what you read.
2. Follow more people yourself.
Here's why:
• The fastest way to get more followers is to start following more people. A lot of the people you follow will follow you back. So if you follow more people, you'll get more followers. • You can also put links to your Twitter profile on your blog, website, Squidoo lenses, facebook page, and any other social networking sites where your fans and friends go. The services that can help you get more followers include:
• TweetAdder • SocialOomph
3. Regularly unfollow people who haven't followed you back.
This is especially important to avoid follow limits. The first limit you'll probably hit is when you've followed 2,000 people. You won't be able to follow any more until you have 2,000 followers. As you follow and get followed, it'll become time-consuming to "clean up" your list (unfollow people who aren't following you back). There are services that can help you with that:
