 Present your followers with unique and updates content about how you define yourself on your profile:

Twitter followers will always be interested in reading something new, related to the profile of the user that they are following. Based on the information you have disclosed on your Bio, such as hobbies, activities or interesting events, users are always interested in seeing relevant posts as they will assume that you are going to post about it sometime in future. You can also post in the summary that you are going to follow back in case someone starts following you. This will result in increase in the number of followers.

You would be in a good position if you stay away from controversial issues like sex, religion and politics. Having a wide range of audience also deserves respectful and gives you a sense of responsibilities when posting on such issues.

Don't have long conversations over Twitter with specific individuals. Every time you reply to any person, your tweet is sent to your subscribers and is visible to them. If you need to communicate then you can directly message them.

Do not radically change the content on Twitter after you've already established a remarkable presence. People like consistency and followed you for a specific reason.
