This post I recently found in my Twitter feed was helpful on the question of gaining followers on Twitter. https://www.socialquant.net/more-followers-on-twitter/
Some highlights include:
- Create a list of great content producers.
- Optimize your bio for keywords.
- Use images in your tweets.
To it, I would also add add
- Tweet during big events like Super Bowl. (As did Oreo cookies)
- Tweet using a trending hashtag (My class’ Star Trek video)
- Interact with popular and influential people (Austin Kleon)
- Regularly share great content (Show your work)
- Volunteer to share your expertise (Collin Mac – answers photography questions in online forums)
- Be funny
- Tap into memetics
