X (Twitter) Hashtags
Most popular #twitter hashtags for Instagram, TikTok and YouTube Shorts. Select any tags and copy them.
Quick answer: X, formerly Twitter, allows as many hashtags as you like but its help center recommends no more than two per post. Hashtags on X work best for live events, chats and ongoing conversations where people actively search the tag. For everyday posts, clear wording usually matters more. On Instagram, the limit is 5.

About #twitter content
Hashtags started on Twitter, and X still treats them as clickable links to a search for that term. The platform's own guidance is short: use hashtags on relevant topics and keep it to no more than two per post. Posts with a string of tags tend to look like spam, and they take room from the actual message.
Where hashtags earn their place on X is real-time conversation: a sports match, a conference, a TV premiere, a breaking story, or a scheduled community chat. People follow those tags live, so the right one puts you in the middle of the discussion. Check the tag in search first to confirm it is the one people are using.
For evergreen posts, X search matches normal words too, so a precise sentence often does the same job. The Instagram sets below cover content commonly shared across both platforms.
Tips for tagging X (Twitter) posts
- Use one or two tags, in line with X's guidance. Put them where they read naturally, often at the end.
- Search the tag before using it. Confirm it is the one the conversation actually uses and that it has not been taken over by unrelated content.
- For events and chats, the official tag matters most. Organizers usually publish it on their profile or event page.
- Moving a thread to Instagram? Rebuild tags to five with the hashtag limit guide. For other text-first platforms, see Threads hashtags and LinkedIn hashtags.
Hashtags to avoid
| Hashtag | Why skip it |
|---|---|
#trendingnow | Generic on X; use the actual event tag people are searching instead. |
#followback | Follow-exchange tag that attracts spam accounts. |
#retweet | Asks for a repost rather than describing the post, and reads as engagement bait. |

#twitter hashtag FAQs
How many hashtags should I use on X?
X's help center recommends no more than two per post. You can technically add more, but long lists look spammy and crowd out your message.
Do hashtags still matter on X?
They matter most for live events, chats and ongoing conversations people follow in real time. For general posts, clear wording that matches what people search is often enough.
Should I use #twitter or #x on my posts?
No. Tagging the platform you are posting on tells nobody what the post is about. Use a topic or event tag instead.
