With millions of videos being created on TikTok every day, it can be challenging for your content to trend and reach the right target audience without TikTok keywords. That’s why, since TikTok integrated SEO features, keywords have become an essential factor in making your videos go viral more easily. If you’re unsure about the benefits of TikTok SEO or how to use it effectively, save these four essential tips to research and optimize your keywords like a pro!

What is a TikTok Keyword?

A TikTok keyword is a word or phrase representing the topic of a video, helping content reach users when they search for relevant content. Simply put, TikTok keywords are the terms users type into TikTok’s search bar to find videos, products, or services.

For TikTok’s algorithm to understand your video’s topic, content creators, sellers, and brand owners must conduct keyword research and integrate primary and related keywords into their content. When done correctly, TikTok recognizes and prioritizes SEO-optimized videos, displaying them at the top of search results.

Why Should You Use Trending TikTok Keywords?

Trending TikTok keywords are popular search terms or topics that are widely used and searched for on TikTok. These keywords are often related to viral videos, challenges, and content that users engage with frequently.

Choosing the right trending TikTok keywords for your video will greatly benefit your content creation process and help your TikTok channel go viral for several reasons:

  • Greater Visibility & Virality: By incorporating trending TikTok keywords into your video, you align your content with current interests, increasing its visibility in TikTok search results and making it easier to reach a larger audience.
  • Increase in Followers: Creating engaging and viral content with trending topics attracts more attention from TikTok users. The more relevant your content is to trending topics, the higher the chances of gaining shares, likes, and new followers.
  • Boost in Sales: TikTok optimizes the shopping journey by showcasing products to potential buyers based on the keywords they search for. By leveraging trending keywords in your product listings and videos, you attract customers genuinely interested in your products, leading to higher conversion rates.

4 Steps to TikTok Keyword Research

Using the right TikTok keywords helps your content go viral and boosts sales. But how do you find the most relevant trending keywords for your channel? Follow these four steps to create your keyword list.

Step 1: Define Your Topic

The first step is to clearly define the topic of the product or service you want to promote on TikTok. Understanding your niche allows you to identify highly relevant keywords that align with your content, making research and keyword selection more effective.

For example:

If you want to build a TikTok channel about cooking skills and knowledge, having a broad topic like “cooking” is too general and difficult to develop targeted content.

Instead, choose a more specific niche—such as vegan cooking tips and recipes. With the topic “vegan dishes”, you can easily find related keywords like vegan nutrition tips, balanced vegan meals, healthy vegan recipes for kids, and more.

Step 2: Research TikTok Keywords

Once you have a defined topic, research relevant keywords with high search volume. You can use various techniques and tools, such as:

Using TikTok’s Search Bar

Type a relevant keyword into TikTok’s search bar, and the platform will suggest the most commonly searched terms related to your topic. Save these keywords for use in your videos to increase their reach and discoverability.

Learn from Top Videos/Top Accounts

Go to TikTok’s search bar, enter the keyword you’re interested in, and hit “Search.” Instantly, the screen will display the most popular videos, accounts, shops, LIVE sessions, and hashtags that users are engaging with the most. Analyze the high-engagement videos to understand why users like their content. You can also gain valuable customer insights from the comments they leave on these videos. Make use of this information and apply it to your own TikTok channel.

Hashtag

In a video, hashtags act as a “book cover,” helping users understand what your video is about. For instance, if you use the hashtag #contentmarketing, it means you want to share content related to content marketing.

When searching for keywords, pay attention to the search volume of hashtags. Hashtags with high search volume indicate trending keywords that many people are interested in.

Use TikTok Keyword Insights Tool

Keyword Insight is a tool provided by TikTok to support content creation. It helps marketers discover high-performing keywords for TikTok advertising. By analyzing keywords, you can identify trending terms and incorporate them into your strategy.

This tool is user-friendly. Simply enter any keyword into the search bar, and you’ll be able to collect relevant data and refine your search results based on location, industry, advertising objectives, keyword type, and time frame.

Use Google Keyword Tools

Besides TikTok’s built-in search features, you can also research keywords using Google tools. Some recommended keyword research tools include:

  • Google Search Box
  • Keyword Planner
  • Ahrefs

Step 3: Create a TikTok Keyword List

Once you’ve found relevant potential keywords, compile a list and use them strategically in your videos. The keyword list should include:

  • Keywords (categorized into primary and secondary keywords)
  • Competition level (Low – Medium – High)

Step 4: Select TikTok Keywords

After researching keywords and compiling a list related to your product or service, the next step is to select the best keywords and determine how frequently to use them for TikTok SEO optimization.

You can categorize keywords into three types:

  • Short keywords: These help increase brand awareness and reach. They usually have high search volume but also high competition and low conversion rates.

    • Example: Marketing, Content
  • Long-tail keywords: These provide more in-depth information, attract potential customers, and encourage actions like likes, comments, and messages.

    • Example: Digital Marketing, Content TikTok
  • Detailed keywords: These specify a unique feature of the product or are associated with a specific brand. While they have lower search volume, they yield higher conversion rates.

    • Example: Digital Marketing for Fashion Companies, Content TikTok for Beginners
