Trending Hashtag: Definition, Examples & Best Practices
A trending hashtag is a topic or phrase marked with the “#” symbol that’s quickly gaining attention on social media. It highlights what people are talking about in real time and helps your content reach a wider audience by tapping into popular conversations.
What Is a Trending Hashtag?
A trending hashtag is a word or phrase preceded by the “#” symbol that suddenly spikes in popularity on platforms like Twitter, Instagram, TikTok or LinkedIn. When you attach a trending hashtag to your post, you’re plugging into a live conversation—boosting your chances of being discovered by new followers.
How Do Trending Hashtags Work?
Social networks track hashtag usage in real time. When a topic gets a lot of mentions in a short time, it appears in the “Trending” or “Explore” section. The exact algorithms vary by platform, but factors often include:
- The volume of posts using the hashtag
- The velocity (how quickly it’s being used)
- The location or demographic of users
Once a hashtag trends, it stays visible until the conversation cools off or a new topic takes over.
Examples in Influencer Marketing
1. #ThrowbackThursday (#TBT): Influencers share nostalgic photos every Thursday. DTC brands often jump in with a “then vs. now” twist to humanize their story.
2. #TikTokMadeMeBuyIt: Creators showcase products they discovered on TikTok. This tag helps brands track viral sales boosts.
3. #BlackFriday and #CyberMonday: Seasonal trends that drive massive traffic. Brands use these tags to highlight flash sales or exclusive bundles.
4. Localized Trends: A coffee shop might use #SeattleEats when that tag trends locally, attracting hungry followers in the neighborhood.
Why Trending Hashtags Matter for Brands and Creators
Visibility: Trending tags put your content in front of users who aren’t already following you. Engagement: People browsing trends are primed to interact—likes, comments, shares. Relevance: Riding the wave of a current topic shows you’re in tune with your audience.
Common Misconceptions and Variations
- Misconception: More hashtags = more reach. Overloading your post with irrelevant tags can look spammy.
- Misconception: Trending equals guaranteed engagement. If your content isn’t a good fit, people will scroll past.
- Variations: “Trending Topics,” “Top Hashtags,” or even trending audio clips on TikTok work on the same principle—capitalizing on what’s hot right now.
Practical Tips for Using Trending Hashtags
1. Check Relevance: Make sure the hashtag aligns with your message or product.
2. Combine Tags: Mix 1–2 trending hashtags with niche tags specific to your industry.
3. Monitor Tools: Use Twitter’s Explore page, Instagram’s Search, or TikTok’s Discover tab daily.
4. Act Fast: Trend lifespans can be hours, not days. Post while the topic is still hot.
5. Track Performance: Use analytics to see which tags drive the most clicks or sales.
By understanding and using trending hashtags strategically, you can connect with broader audiences, boost engagement, and keep your brand conversation fresh and relevant.
