How Many Hashtags Should You Use on TikTok?

If you have searched for how many hashtags to use on TikTok, you have probably found a dozen different answers. Some guides say three, some say five, some say fifteen. Few of them tell you where the number comes from. The honest answer is that, as far as we could verify, TikTok has no official hashtag count limit, so the right number is the one that serves the video and fits your caption.

If your question is a little different, these guides cover it: How to Find Niche TikTok Hashtags Using Search Suggestions; The #fyp Myth: Do Popular TikTok Hashtags Really Help?.

This guide explains what we do and do not know, how to choose hashtags that describe your video, and how to test your own habits without guessing. Tagbloom is not affiliated with TikTok, and platform features change often, so check the TikTok Help Center and the app itself for current rules before you rely on anything here.

What TikTok has and has not said

As of this writing, we could not find an official TikTok statement that sets a maximum number of hashtags per video. That is different from Instagram, which has said it is limiting captions on posts and reels to 5 hashtags. Do not carry Instagram rules over to TikTok automatically.

What does exist is a caption character limit, and hashtags count towards it. That limit has changed over time, so we will not quote a number here. Open the caption box in the app and watch the counter instead. In practice the limit, not a hashtag rule, is what stops you from adding too many.

Also keep in mind that nobody outside TikTok can tell you exactly how its systems use hashtags. TikTok has described using captions, on-screen text, sounds and spoken words to understand videos, so tags are only one of several signals.

How many hashtags to use on TikTok in practice

Since there is no verified official number, think in terms of purpose. Each hashtag should earn its place by doing one of three jobs:

• Describe the topic. For example, a video about knitting a hat might use a tag for knitting and a tag for beginners.
• Describe the audience. A tag for a community or interest group can help the right viewers recognise the video.
• Describe the format or series. A tag you use consistently for a recurring series lets viewers find the set.

For most small accounts, a short list of three to five relevant tags is a sensible starting point. That is a practical habit, not a rule from TikTok, and you should feel free to use fewer or more. If you cannot say what job a tag does, leave it out.

A longer list is not automatically harmful, but it can crowd the caption, hide the plain-language sentence that explains the video and look like a pile of tags added without thought.

Prioritise readable captions

Viewers read your caption faster than you think. A caption that is mostly hashtags gives a person nothing to read and gives the platform little context. Write one clear sentence first, in the words a viewer might actually type into search, then add tags after it.

If you want to go deeper on this, our guide to TikTok SEO and keywords in captions covers how to write captions, voiceover and on-screen text so that they work together.

Capital letters in multi-word hashtags, such as #BeginnerKnitting, make them easier to read and are friendlier to people using screen readers. Spaces and most punctuation do not work inside a tag, so write each phrase as one word.

Mix broad and niche tags carefully

A broad tag describes a large topic, such as #cooking. A niche tag describes a specific one, such as #onepotvegetarianmeals. Broad tags attract many videos, so yours is one among a great many. Niche tags attract fewer videos and a more specific audience. Neither is automatically better.

A reasonable pattern is one broad tag for the general topic and two or three specific tags. You can find specific ideas by typing a topic into the TikTok search bar and noting the suggestions that appear. Those suggestions can show what people type. We cover this in how to find niche TikTok hashtags using search suggestions.

The Tagbloom tool labels phrases as Broad, Niche or Long-tail. That label is an estimate based on how specific a phrase is. It does not know live search volume, so treat it as a sorting aid rather than a measurement.

Avoid tags that do not describe the video

Using a tag that has nothing to do with your video can mislead viewers. If someone searches a topic and finds an unrelated clip, they scroll away, and you gain nothing. It can also look like spam.

Be especially careful with tags that are very generic, such as #fyp. TikTok has not said that these tags unlock the For You feed, and we know of no public evidence supporting a special boost. They are optional. We explore this in the #fyp myth.

Do not copy a long block of hashtags from another creator. Their video, audience and goals differ from yours, and you cannot know why they chose those tags.

Worked example: choosing tags for one video (hypothetical)

This is a made-up illustration, not a real account and not a prediction of results.

Imagine a creator who posts a thirty-second video showing how to repot a houseplant.

1. She writes a plain first sentence: "How to repot a houseplant without hurting the roots."
2. She asks what the video is about. Topic: repotting. Audience: new plant owners. Format: a quick how-to.
3. She types "repot" into the TikTok search bar and notes two suggested phrases that match her video.
4. She chooses four tags: one broad (houseplants), one topical (repotting), one for the audience (plantsforbeginners) and one for her recurring series (plantcarebasics).
5. She leaves out an unrelated trending tag, because it does not describe the video.

Summary of the hypothetical example: a plain sentence, four tags that each have a job, and one tag rejected because it did not fit. The method is the point, not any promised outcome.

Test your own tag habits

The best answer for your account comes from your own videos. Try a simple test over a few weeks:

1. Post videos with three to five tags for a set period and note the results.
2. Then change one thing, such as using only two tags, for a similar number of videos.
3. Compare views, watch time, shares and saves in TikTok's analytics. Menu names change, so look for the analytics section in the app.
4. Keep a note of what you changed so you can repeat what works.

Keep the topics and formats as similar as possible, otherwise you will be comparing videos for different reasons. Remember that a single video can do well or badly for reasons unrelated to tags, so look for patterns over several videos. Our guide to TikTok analytics explains what each number means.

Frequently asked questions

Is there a maximum number of hashtags on TikTok?

As far as we could verify, TikTok has not published an official hashtag count limit. Hashtags do count towards the caption's character limit, which has changed over time, so check the counter in the app. Confirm current details in the TikTok Help Center.

Should I use the same hashtags on every video?

Not for everything. A consistent tag for a series can be useful, but your topic tags should describe each video. Repeating the same block on every video, even when the content differs, makes your tags less accurate.

Do more hashtags mean more views?

We cannot promise that, and we know of no public evidence that adding more tags increases views. Relevant tags may help people and the platform understand what a video is about. Clear captions, good hooks and useful content matter at least as much.

Conclusion

There is no verified official number of hashtags for TikTok, so choose tags by purpose: describe the topic, the audience and the series. Start with a few relevant tags, write a readable caption and compare your own results over time. Your next step is to open the free tag generator, list ideas for your next video and keep only the ones that truly describe it.
