Viral Hashtags on Threads & Bluesky: What Works in 2025 (Without Spam)

This year, everyone wants to know one thing: how do you leverage viral hashtags on Threads and Bluesky without looking like spam? Hashtags are still around, but they have evolved. It's no longer about including a large number of them under every post. Instead, they are related to timing, context, and accuracy. Threads and Bluesky are now both essential for real-time interaction, and hashtags are no longer just for clutter; they are now used to connect people.

Statista reports that in 2024, more than 62% of social media users will utilize hashtags to discover new content. This indicates that hashtags remain crucial for achieving reach. Another HubSpot study found that posts with correctly chosen hashtags had 23% more interaction than posts without any hashtags.

This means that the formula hasn't disappeared; it has just changed. This essay will explain how viral hashtags function in 2025, why context is essential, and how to utilize them effectively with tools like scheduling and analytics to increase followers.

What Makes a Hashtag Viral in 2025?

The primary reason viral hashtags proliferate remains the same: a large number of people utilize them. The types of hashtags that go viral have changed. Hashtags will remain popular in 2025 not just because of the number of people who use them, but also because they are humorous, relate to current culture, or are breaking news. One funny hashtag can be better than 10 boring ones.

For example, look at humorous hashtags. A post with a clever twist usually gets more attention than a plain, overused tag. People online often post funny things. A 2024 survey found that 80% of users were more likely to share something that made them laugh. This is why hashtags like #NoFilterNeeded and #WorkFromCouch went viral: not because people had to, but because they felt right.

Threads and Bluesky: The New Hashtag Battlegrounds

Threads and Bluesky are becoming real threats to Twitter's old hashtag culture. Hashtags on Threads aren't just for show; they are part of conversations. Using popular hashtags here will get you involved in conversations, rather than just adding you to a sea of random messages.

Bluesky works similarly, but it has an extra layer: because it is decentralized, popular tags can start in smaller communities and then expand to the whole site. To expand on Bluesky, you typically need to get in on these micro-trends early. If you can find a hashtag that is growing in a small group and participate in a real way, you can ride the wave before it reaches its apex.

This is why scheduling Bluesky postings is becoming a popular approach. Creators plan their posts ahead of time so they can always join conversations at the right time. It's not only about the tag; it's also about being there at the appropriate time.

Avoiding the Spam Trap

Spam has always been a problem with hashtags. Posts that have too many of them seem desperate. Platforms notice too—algorithms in 2025 will deliberately lower the rank of content that looks crammed. So when we question what makes viral hashtags succeed today, the response is to hold back. It's much better to use one to three well-placed hashtags than ten that are scattered throughout.

When you post on Threads, make sure your hashtag is related to the main discussion you're joining. When you post on Bluesky, ensure your hashtag aligns with the community's tone. Using hilarious hashtags only works if the humor fits with your brand voice; otherwise, it seems forced.

Use hashtags like you would use spices. If you don't add enough, your content will be boring. If you add too much, the dish will be too much. The perfect pinch makes things taste good and keeps them in balance.

Planning for Reach with Scheduling Tools

To reach your goals, you need to be consistent. That's when scheduling comes in. Instead of rushing at the last minute, use a post threads scheduler to plan out your posts and match them with hashtags in an innovative way. Learn more about effective Threads scheduling strategies. Scheduling Bluesky posts is especially helpful because viral trends can emerge at any time, and having evergreen content ready to go allows you to respond to trends promptly.

With analytics, you'll not only know which viral hashtags worked, but also what times got the most people to participate. Hootsuite's 2024 study says that accounts that coupled scheduling with hashtag analysis had 32% more engagement than those that didn't. Planning doesn't kill authenticity; it makes it stronger.

How to Grow on Bluesky with Hashtags

Bluesky is still a relatively new network, and many people are learning how to increase their followers on it. For comprehensive strategies on Bluesky growth, see our guide on how to get followers on Bluesky with effective scheduling habits. Hashtags here aren't for getting a lot of people to see your posts; they're for finding the correct rooms. By publishing under smaller, more specific tags, you increase your visibility in active communities. These small interactions accumulate over time, leading to gradual growth in followers.

Using viral hashtags in this way creates a two-layered strategy: one for community engagement and one for visibility. You can reach both the interested insiders and the curious outsiders when you employ them together. That's how you grow and create trust without losing your realness.

Humor, Humanity, and the Power of Funny Hashtags

Not every viral hashtag has to be serious. Some of the most remembered ones are fun. Humor works because it evokes emotions that linger with people. People remember what made them laugh and share it without thinking twice.

Brands that use amusing hashtags get more interaction because humor cuts through formality. For instance, when a food brand posts "#DidntShareTheFries," it makes a bare mention of a product into something funny and sympathetic. The most important thing is to be real. Your hashtag should seem like something your audience would say, not like business jargon that tries too hard.

Conclusion

The question in 2025 isn't whether hashtags are essential; it's how you use them. Viral hashtags are still the best way to get attention, but they only succeed when they're connected to a real conversation, humor, or something culturally relevant. Threads and Bluesky reward people who are consistent.

You can plan and participate in real-time with tools to submit threads or schedule Bluesky postings. If you want to get more followers on Bluesky, you need to mix niche tags with more popular viral tags and do it without spamming. Hashtags aren't magic, but they can be instrumental when used correctly. Make sure they are intentional, human, and fun. That's how you stop looking like a bot and start looking like you're in the conversation.
