Threads added hashtag support after launch, but the platform still leans more on topic tags you can follow directly than on a browsable tag feed the way Instagram once had. A tag here works less like a discovery net cast wide and more like a label that puts your post into a smaller, more specific stream someone already chose to follow.

How Threads actually uses tags
A hashtag on Threads links to a topic page and, in some cases, a followable topic stream, closer to how X’s tags work than how Instagram’s used to. Because Threads is built for reply-driven conversation, a tag matters less than whether your post actually gives people something to respond to. A generic post with a hashtag attached rarely outperforms a specific one with none.
How many to use
One or two is the sensible range here, more than that reads as an attempt to game a feed that rewards conversation, not tag density. A Threads hashtag generator can suggest a relevant one or two quickly, and a hashtag counter keeps the count in check.
What to do instead
Write a post that gives people something specific to reply to, that does more for reach on Threads than any tag will. Save a hashtag for when you’re genuinely tying a post to a topic or community stream people follow, not as a default habit carried over from another app.
