How Many Hashtags Can You Use On TikTok? (2025)

As of 2025, TikTok has no official limitation on the number of hashtags you can technically use on a post.

However, TikTok does impose certain character limits on the caption (description) field and the comment section, which indirectly influences the number of hashtags you can physically type in these text areas.

Specifically, you cannot exceed:

• TikTok description character limit: 4,000 characters.
• TikTok comment character limit: 150-200 characters on the web, 10,000 characters in the app.

How Many Hashtags Should I Use On TikTok?

Just because you can use many hashtags for TikTok doesn’t mean you should.

So, how many hashtags on TikTok should you use in 2025? 

Let’s see what industry experts recommend:

Social Insider, specializing in social media insights, suggests a sweet spot of 3-5 highly relevant hashtags per post. They warn that using an excessive number can make your post look cluttered or spammy, potentially hindering its reach..

According to Buffer, another trusted source for social media marketing, you should stick to around 4-6 well-chosen tags per video for optimal results.

So, what do the experts at GDT Agency say? I’ve spoken with our TikTok team and received the following advice.

Try a video with different quantities: none at all, just one hashtag, five hashtags, ten, or more.

Then, track which number or set of hashtags works best for your account and content.

Overall, there is no one-size-fits-all answer. Test to find your ideal hashtag quantity.

Best Expert Strategies For TikTok Hashtags

While the exact number isn’t set in stone, employing smart strategies for selecting the right hashtags for TikTok is vital. 

Here’s how to ensure you’re using them effectively to maximize video performance in 2025:

#1. Start with general hashtags

General hashtags connect you to the general community of people interested in that industry/topic.

Example: #seo, #seotips.

#2. Add niche-specific or branded hashtags

Add 1-2 hashtags that precisely define your field or the specific topic of your video. 

For example, if you’re demonstrating a new SEO keyword tool, add relevant tags like #seotools or #keywordresearch.

This is also the place to include your branded hashtags. These help build brand recall, increase your chances of kickstarting a trend, and encourage user-generated content, especially if you run challenges or marketing campaigns.

Example: #haideraliseo (the branded hashtag for SEO expert Haider Ali on TikTok).

#3. Capitalize on trending TikTok hashtags

Stay updated on the currently popular TikTok hashtags within your industry. You can use the TikTok Creative Center to discover trending hashtags for free.

Look for newly trending tags by selecting <New to top 100>. They might be less saturated than long-established popular ones, offering a better chance to stand out.

#4. Use problem-solving hashtags

Think about the pain points your video addresses or the solutions it offers. Add 1-2 hashtags reflecting these.

For instance, if your TikTok video demonstrates an SEO tool that helps boost blog traffic, use tags like #increasewebsitetraffic.

This aligns your content directly to the specific needs or solutions your audience is searching for.

#5. Include target audience hashtags

Lastly, consider who your ideal viewer is, and add hashtags that speak directly to your desired demographic. 

For instance, #contentwriter could be the target audience for a video promoting an SEO keyword research tool.

#6. Test and refine

Conduct A/B tests using similar videos with different sets or numbers of hashtags.

Leverage TikTok’s built-in analytics tools to monitor key metrics like views, likes, comments, shares, reach, and follower growth. 

These insights can help you understand which quantity or set of hashtags performs best.

If a hashtag strategy fails to drive the results you want, don’t hesitate to pivot.

Adjust the types of hashtags you use (trending, niche, audience-specific) and the quantity.

Remember, leveraging the right viral and relevant TikTok hashtags can significantly boost your content’s visibility and engagement.
