Threads doesn't do hashtag lists. Each post gets one topic tag, which shows as a link and puts your post in front of people searching that topic. Here's how to add one, how to choose the right tag, and a checker to test your tag before you post.

Meta's advice: "you can only tag one topic per post, so select the topic that best represents what you are saying."
| Threads topic tags | Hashtags elsewhere | |
|---|---|---|
| Per post | One | Usually several |
| How it looks | A link, no # symbol | #word inside the text |
| Spaces | Allowed - "slow cooker dinners" | Not allowed - #slowcookerdinners |
| Where it leads | Search results for that topic | A hashtag page or feed |
| Best use | The one topic your post is really about | A mix of broad and niche tags |
Paste your post and the tag you're thinking of. The checker flags common mistakes and shows how the tag will look.
Aim for the most specific tag people actually use. Broad tags are crowded; tiny ones have no audience.
Check it has recent, on-topic posts - that's your audience.
Note the tags on strong posts from accounts like yours.
Add it to a custom feed to see what does well there.
Try 2–3 tags over a few weeks and compare views in Insights.
Reuse a small set of tags that match your content pillars.
Local businesses: try your town or city in the tag.
Starting points to search and check. Pick tags with recent, relevant posts - activity changes all the time.
