Do you want to see more posts about interesting topics in your Home timeline? And do you want your own posts to be noticed by others?

Here's how to do both these things:

1. Search for a hashtag you're interested in
2. On the results page, click the + or Follow button in the top right corner
3. Posts with that tag will start appearing in your Home timeline
4. Follow lots more tags
5. Include hashtags in your own posts, tag followers will then see your posts

@feditips I don't have a follow or + button when I search up hashtags it's just the hashtag at the top and all the results underneath

@gothiccgamer

Are you on the Android official Mastodon app? That doesn't have a follow button yet.

If so, I'd strongly recommend switching to the third party apps Tusky or Fedilab.
