Does Bluesky Use Hashtags

Yes. Bluesky supports hashtags. A hashtag on Bluesky is a # prefixed word or phrase that functions as a clickable link, taking users to a feed of all posts using that tag. Hashtags are used for topic discovery, custom feed curation, and community participation on the platform.

Bluesky hashtags work differently from hashtags on Instagram or TikTok in one important way: Bluesky users can follow specific hashtags to include them in their personal feeds. When you follow a hashtag on Bluesky, posts containing that tag from accounts you do not follow appear in your Following feed. This makes hashtags a more active discovery mechanism on Bluesky than on most other platforms, where hashtags are primarily a search tool.

How Hashtags Work on Bluesky

Clickable topic links. Any # prefixed word in a Bluesky post becomes a clickable link. Tapping the hashtag opens a feed of posts using that tag across the platform.

Follow a hashtag. Bluesky users can follow hashtags directly. Go to the hashtag feed page (by tapping the tag or searching for it) and tap Follow. Posts containing that hashtag from any account then appear in the Following feed alongside posts from accounts you follow.

Custom feed integration. Many Bluesky custom feeds are built around specific hashtags. Creators who build topic-specific custom feeds use hashtag signals to determine which posts appear in those feeds. Using the right hashtag can get your post included in curated topic feeds followed by relevant audiences.

Hashtags count toward the 300-character limit. Bluesky posts are limited to 300 characters. Each hashtag character, including the # symbol and the tag text, counts toward this limit. Keeping hashtags short matters more on Bluesky than on platforms with longer post limits.

How to Follow Hashtags on Bluesky

Following a hashtag on Bluesky brings posts using that tag into your Following feed:

1. Search for the hashtag in Bluesky's search bar, or tap any clickable hashtag in a post.
2. The hashtag feed page opens, showing recent posts using that tag.
3. Tap Follow (the button appears on the hashtag feed page).
4. Posts containing that hashtag now appear in your Following feed alongside posts from accounts you follow.

To unfollow a hashtag, go back to the hashtag feed page and tap the same button to unfollow.

This feature makes hashtags on Bluesky function more like topic subscriptions than simple search filters, which is why choosing specific and relevant hashtags is more important on Bluesky than on platforms where hashtags primarily aid search.

Bluesky Trending Hashtags

Bluesky does not have a native trending hashtags page equivalent to Twitter's Trending Topics. There is no official public list of real-time trending hashtags published by the platform.

To find currently active hashtags on Bluesky:

Browse topic custom feeds. Bluesky's custom feeds (accessible through the Feeds tab) are often built around active communities. Browsing posts in relevant custom feeds reveals which hashtags are currently in use within that community.

Check active communities. Tech, journalism, science, and media communities on Bluesky have established hashtag conventions. For example: #Tech, #OpenSource, #SciComm, #ActuallyAutistic, #BlackSky, and #IndieWeb have consistent usage in their respective communities.

The generator produces hashtag suggestions based on your topic input. For the most current activity levels, check the suggestions against Bluesky's search results to verify active use before posting.

Best Bluesky Hashtags: How Many to Use

1 to 2 hashtags per post is the community norm. Bluesky's user base which skews toward tech, journalism, and media favors conversational, substantive posts. Heavy hashtag use reads as out of character for the platform's culture. Most well-performing posts on Bluesky use one specific hashtag or none, with occasional posts using two.

Specific hashtags outperform broad ones. #Tech has massive competition and low targeted reach. #IndieHackers or #OpenSource reaches a more defined audience where a relevant post has a genuine chance of being seen. The generator returns hashtags at different specificity levels prioritize the more specific suggestions for niche topics.

Place hashtags at the end. Inline hashtags interrupt sentence flow. Placing them at the end of the post after the main text keeps the post readable. Example: "Just shipped a new feature for our API. Two weeks of iteration to get the error handling right. [line] #OpenSource #IndieHackers"
