If you want more followers on Twitter, you need to follow people too
If you want followers on Twitter, you need to follow people first. And you need to make sure they are the right people. If your tweets are interesting, some of these people will follow you back.
For example, if you’re a Dermatologist, think about who will be interested in what you have to say. You may want to follow health & beauty bloggers, Eczema charities, beauty bloggers, and Psoriasis support groups.
