How to get popular on twitter?

[Spidey-Man]

I made a twitter today and I already got 4 followers (I don't know any of the. Though). I want to be an author and I recently started writing my first novel, so it would be great if I got a lot of followers so that the book would sell well. I'm not really sure what I should tweet about or how to get more followers. How do I get famous on twitter?

To get famous on twitter u tweet current stuff. U follow people with the same interests and tweet. Basically im a mcfly fan (and band) and if they tweeted like "Im so excited for the tour ect" then youd tweet about the time. Im proberly not making a lot of sense but i made twitter 3 years ago and i only have 483 followers. U tweet about cool stuff. Search through other people and see what they tweet about. Follow people with yoir interest oh and if your profile picture is an egg simble then people wont follow. Change your picture to one of yourself. Write a decent bio about yourself, hoped i helped

I would say, it is a good start that you already got 4 followers to your twitter account. Anyway you will need more followers in order to get popular on twitter. To get more followers to your account you must follow these instructions including -
Upload a decent profile picture.
Tweet frequently on your subject/novel.
Try to retain your followers by tweeting as per their interest.
