Byhello@wantseo.co.uk

It’s 2025, and the digital world never slows down. Social platforms rise and fall, algorithms evolve overnight, and trends shift in the blink of an eye. Amid all this change, one question keeps cropping up for business owners trying to build their brand on TikTok: Are hashtags still relevant?

TikTok’s explosive growth and uniquely tailored algorithm have made it a key player in the world of online visibility. But with its ultra-smart feed and viral nature, do hashtags still hold weight — or have they become digital wallpaper?

In this article, we’ll unpack the truth behind TikTok hashtags, whether they matter for reach and engagement, and how to use them effectively in 2025. If you’re serious about growing your brand through smart content and SEO-savvy thinking, you’ll want to read on.

Key Takeaways

  • Hashtags are still relevant on TikTok, but their role has shifted from discovery to context and categorisation
  • Strategic use of niche and trending hashtags can boost visibility and engagement
  • Overstuffing posts with irrelevant or generic hashtags can hurt more than help
  • TikTok’s algorithm prioritises content quality and watch time over hashtags, but they still influence searchability
  • Hashtags should support your content strategy, not replace it

The Role of Hashtags on TikTok Today

Let’s start with the basics. Hashtags on TikTok serve several purposes, but their primary functions have evolved.

  • Categorisation: Hashtags help TikTok understand the content of your video, making it easier to serve to the right audience
  • Search discovery: Users still search hashtags for topics or trends, especially for challenges, tutorials, or niche communities
  • Context signals: They tell the algorithm what your video is about and who might like it, especially in the absence of a full caption
  • Trend tapping: Jumping on trending hashtags can give your content a temporary lift, provided your content is relevant and engaging

So yes, hashtags are still a thing — but they’re only one part of the puzzle.

How to Use Hashtags Effectively on TikTok

If you want your content to work harder and smarter, hashtags need to be used with purpose. Here’s how to approach them in today’s landscape:

  • Mix popular and niche hashtags: Use 1–2 trending or broad hashtags (#fyp, #viral) with 3–5 niche or topic-specific ones to reach the right viewers
  • Prioritise relevance: A video about bookkeeping for freelancers shouldn’t use trending dance hashtags just for visibility — it sends the wrong signals
  • Research hashtags regularly: What worked last year might not work now. Use TikTok’s search bar and tools like TikTok Creative Centre or Trend Discovery to explore what’s current
  • Consider branded hashtags: If you run a campaign or challenge, creating a custom hashtag can encourage engagement and community growth
  • Keep your captions clear: Your text and hashtags should complement, not compete — clarity helps both viewers and algorithms

A recent case study from Search Engine Journal, showed that videos using 4–7 hashtags, including at least one niche hashtag, had better reach and engagement compared to those that only used generic ones like #fyp or #trending.

Challenges and Misconceptions About TikTok Hashtags

There’s no shortage of advice online, but not all of it’s helpful. Let’s clear up some common myths:

  • “Just use #fyp and you’ll go viral.”
    This used to help — now it’s mostly ignored. TikTok’s algorithm is far too advanced to be gamed by generic tags.
  • “More hashtags = more reach.”
    Not always. Overloading your caption with irrelevant or excessive tags can make your content look spammy and confuse the algorithm.
  • “Hashtags are pointless now.”
    Incorrect. They still play a key role in content discovery when used correctly. Especially for small creators or niche businesses, they’re still a powerful tool.
  • “You don’t need SEO on TikTok.”
    Actually, TikTok is becoming more search-led. People use it to find tips, tools, and reviews — and that’s where hashtags, keywords, and structured content come into play.

Want SEO works with businesses to align their social content with broader keyword strategies — meaning your TikTok videos don’t just entertain; they rank, too.

TikTok Hashtags and the Future of Social Search

Here’s the exciting bit. TikTok is no longer just a social platform — it’s becoming a search engine.

  • TikTok search is on the rise: Especially among Gen Z and younger millennials, TikTok is being used like Google for “how-to” queries, product discovery, and reviews
  • SEO and hashtags are merging: Using hashtags that match user search intent is becoming just as important as your visuals
  • Content-first wins: Hashtags support content — they don’t replace it. If your video doesn’t engage within the first few seconds, hashtags alone won’t save it
  • Voice search and AI: As TikTok enhances its algorithm with AI and voice detection, hashtags will likely continue to play a supplementary role, giving signals to support what’s being said or shown

The real win comes when your content is found, watched, and engaged with. Hashtags help with the first step, but it’s your creativity, clarity, and strategy that drive the rest.
