How to use it

How to Use the TikTok Keyword Generator

ContentStudio's free TikTok keyword generator suggests relevant keywords for your TikTok captions, bios and content plan based on your niche, topic or audience.

  1. Enter a niche, topic or audience

    Examples: "home organization", "fitness for beginners", "small business marketing", "marketers".

  2. Generate

    Click Generate TikTok keywords now to get a list of keyword ideas.

  3. Pick the closest matches

    Keep the phrases that describe the video you are about to make. Specific, longer phrases are easier to rank for than one-word terms.

  4. Check them in TikTok

    Type each phrase into TikTok search. If autocomplete suggests it and the results are active, it is worth using.

  5. Use them everywhere TikTok reads

    Say the keyword early in the video, show it as on-screen text, and put it in the caption and, for your main topic, in your bio.

What TikTok keywords are

What Are Keywords on TikTok

TikTok keywords are words and phrases that TikTok's search and recommendation systems use to understand what a video is about and who to show it to. Since TikTok made search a main way to find content, the text in captions, on-screen text, spoken audio and profiles has become part of how videos get found.

Many people now use TikTok like a search engine for recipes, products, travel tips and how-tos. If your video says and shows the phrase they type, it has a better chance of appearing in the results and in the "Others searched for" suggestions under videos.

Where to put keywords

Where to put TikTok keywords

Spoken in the first seconds

TikTok transcribes speech. Saying "easy meal prep for the week" early tells the app the topic.

On-screen text

Add the keyword as a text overlay or title card. It doubles as a hook for viewers.

Caption

Put the main phrase in the first line of the caption, written naturally. Write it with the TikTok caption generator.

Hashtags

Turn one keyword into a hashtag, such as #mealprep. Find more with the TikTok hashtag generator.

Name and bio

Your profile name and bio tell TikTok what your account is about. Add your niche keyword once.

Photo Mode titles

Photo carousels have a title field and descriptions. Put the keyword in the title.

Keyword research

TikTok Keyword Research: How to Find Keywords

TikTok keyword research differs from Google keyword research because TikTok does not publish search volumes the way Google Keyword Planner does. These are the research methods available:

TikTok search bar autocomplete: type a broad topic into TikTok's search bar without pressing Enter. The suggestions are terms TikTok sees people search for. Add a letter after your topic ("meal prep a", "meal prep b") to see more.

Creator Search Insights: inside the TikTok app (search "Creator Search Insights" or find it in Creator tools where available), TikTok shows what people in your categories are searching, including topics with few videos that answer them. It is the closest thing to a TikTok keyword volume tool.

TikTok Creative Center, Keyword Insights: the Creative Center (ads.tiktok.com/business/creativecenter) has a Keyword Insights tool. It shows the top keywords and phrases used in TikTok ads, with popularity and performance data. It is built for ad copy, so treat it as a guide to the words that resonate rather than organic search volume.

"Others searched for" and related searches: the suggestions shown under videos and at the top of results reveal how people phrase a topic.

ContentStudio's keyword generator: enter a niche to get a starting list in seconds, then check the best ones with the methods above.

General SEO keyword tools use Google data, so their volumes may not match what people search on TikTok. Always confirm a keyword in TikTok search before building a video around it. For the full process, read our TikTok SEO guide.

Keywords and the algorithm

Keywords for the TikTok Algorithm

The For You Page (FYP) algorithm shows videos to people who don't follow you yet. Keywords in the caption, on-screen text and speech help the algorithm decide which viewers to test a video with first.

Keywords get a video into the right test group. Watch time, rewatches, comments, shares and saves decide whether it keeps spreading. A keyword-packed caption on a weak video won't rank, and a strong video with no keywords may never reach the people searching for it.

Trending keywords

TikTok Trending Keywords

TikTok trending keywords are terms whose searches grow fast in a short window. They are different from evergreen keywords that perform steadily for months.

Posting early in a trend helps because fewer videos compete for the search. Once a topic is saturated, it is much harder for a new video to stand out.

How to find trending keywords on TikTok right now:

  1. Open TikTok Creative Center at ads.tiktok.com/business/creativecenter.
  2. Go to Trends.
  3. Filter by region, time period and industry.
  4. Check trending hashtags, songs and topics with their trend lines.

For real-time search trends, type the first word of your niche into TikTok search and look at the autocomplete suggestions. Suggestions that rank higher than you expect show active search momentum.

Keywords vs. hashtags

TikTok keywords vs. hashtags

Keywords

Plain words and phrases in your speech, on-screen text, caption and bio. They help your video show up when people search.

Hashtags

#-prefixed tags in the caption. They group videos into topic feeds and add a topic signal. Use 3–5 per post.

Use both. Your main keyword can also be one of your hashtags.

What is the difference between TikTok keywords and TikTok hashtags?

Keywords are words and phrases in your caption, on-screen text, spoken audio and profile that TikTok reads to match videos to searches. Hashtags are #-prefixed terms that create topic feeds and add a topic signal. Both help discovery in different ways, so use both in the same post.
Partly. The TikTok Creative Center has a free Keyword Insights tool that shows top keywords from TikTok ads with popularity and performance data. Inside the app, Creator Search Insights shows what people search for in your categories where it is available. ContentStudio's generator gives you a quick starting list for organic content.
Use the same core niche keyword across videos to build a clear topic for your account, which tends to help in TikTok search. Vary the secondary and long-tail phrases on each video so you cover more searches without diluting your account's topic.
Pick one main keyword per video. Say it in the first few seconds, show it as on-screen text, put it in the first line of the caption and turn it into one hashtag. Add your niche keyword to your bio. Then post consistently on that topic with a TikTok scheduler.
Find what people search with autocomplete, Creator Search Insights or a keyword tool. Make a video that answers that search, use the keyword in speech, on-screen text and caption, add 3 to 5 relevant hashtags, and post regularly on the same topic. Watch analytics and repeat what ranks.
Yes. ContentStudio's TikTok keyword tool is free with no sign-up. TikTok search autocomplete, Creator Search Insights and the Creative Center's Keyword Insights are free too. Google Trends helps for rising topics, but it uses Google data, not TikTok's.
TikTok creates automatic captions from speech and uses text on the screen and in captions to understand videos. Saying your keyword out loud and showing it on screen helps make the topic clear.
