Most creators learn how to do YouTube keyword research by picking a high-volume phrase and reverse-engineering a video idea to fit it. The result is content nobody asked for.

This guide flips that order. You start with a topic you can cover well and use research to validate whether there’s demand, what angle the audience expects, and how to increase the video’s odds of showing on YouTube and Google.

Why YouTube keyword research is topic validation rather than idea generation

The YouTube algorithm rewards topical relevance, engagement, and quality over exact phrase matches.

That means your mindset shifts from "what should I make?" to "of the topics I can credibly own, which ones have validated demand worth pursuing?"

The algorithm matches for topics

If you search a specific term on YouTube, you’ll notice that sometimes none of the top results contain that exact phrase in their titles. For example, in the results for “best microphone for youtube”:

YouTube SERP for the term "best microphone for youtube" with the titles of the top three results highlighted.

These videos rank because the algorithm thinks they’re the best answers to the underlying question.

Topic validation checks three things beyond demand

Validation tests topic demand, channel fit, format fit, and business value.

Here’s how to think about those four elements:

Keyword data feeds the demand check directly. The other three depend on knowing your channel and your business. A tool cannot concretely know what you can credibly own.

Validation matters more for video than for blog content

Video is too expensive and time-intensive to produce on speculation, and once published, it can't be iterated on the way a blog post can.

Once a YouTube video is live, you can update the title, description, and thumbnail. But you can't redo the video itself.

Bad ideas either stay public, drag down your channel's average watch time, or get unpublished and re-shot from scratch. Validation is the key step that keeps you out of that situation.

What is YouTube keyword research?

YouTube keyword research is the process of finding video topics with real audience demand that your channel can credibly cover and compete for.

Unlike keyword research for SEO, YouTube rankings depend on engagement signals like watch time and click-through rate (CTR) more than exact phrase fit.

Effective YouTube keyword research enables you to:

YouTube keyword research shapes your entire YouTube strategy.

How to do keyword research for YouTube videos

Here’s how to do keyword research for YouTube videos:

  1. Start with topic ideas
  2. Use YouTube features to find ideas
  3. Evaluate seasonal and regional trends
  4. Analyze your competitors' videos
  5. Use YouTube keyword research tools
  6. Score and prioritize video opportunities
  7. Use AI to expand video angles for each topic

Start with topic ideas

Define the core topics your channel should cover, which are the broad subject areas your audience cares about.

For example, if you run a YouTube channel about content creation, your core topics might include phrases like “home studio setup,” “video editing,” and “on-camera confidence.” Each of those topics can generate dozens of specific video ideas once you start researching.

Write your topic list somewhere you can reference throughout this process. Like a spreadsheet.

We created a YouTube keyword scoring spreadsheet you can create a copy of to use for your research process. We’ll provide more information on how to use it later. For now, just add your keywords in the “Topic / keyword” column.

Use YouTube features to find ideas

Use the initial ideas you came up with alongside YouTube’s built-in features to find ideas grounded in real viewer behavior that you might otherwise miss.

Start with the search bar. Type one of your core topics and look at the autocomplete suggestions. These are real queries people search for, ranked by factors like popularity and similarity.

YouTube SERP with "home studio setup" entered as the term along with the list of autocomplete suggestions highlighted.

To expand your results, try the alphabet trick. This is when you type your topic followed by a space, then a single letter. For example, "Home studio setup a," "home studio setup b," etc. Each letter surfaces a different set of suggestions.

YouTube SERP with "home studio setup c" entered as the term along with the list of autocomplete suggestions highlighted.

Pro tip

You can also place modifiers before your topic — like "best home studio setup" or "cheap home studio setup" — to reveal other angles searchers care about.

Next, go to “Analytics” > “Trends” in YouTube Studio to spot rising YouTube search trends before they peak.

Using Google Trends with the YouTube filter applied shows you whether a video topic is growing, fading, or seasonal — and when to publish for maximum impact.

Go to Google Trends, enter one of your topic ideas, change the search type drop-down from "Web Search" to "YouTube Search,” and change the time to drop-down to “Past 5 years.” You'll see a trend line showing interest over time.

In this example, “home studio setup” seems to peak in December.

Compare multiple topics side by side to see which ones have stronger or more consistent demand.

For example, "home studio setup" spikes around the holidays when people are buying new gear, while “ai video editing” is more steady year-round and has much higher overall demand.

Under the graph, check the "Top queries" and "Rising queries" sections for terms labeled "Breakout," which signal rising demand for topics your competitors may not have covered yet.

If your audience is concentrated in a specific country, change the location drop-down from "Worldwide" to that country to see whether the trend holds locally.

Analyze your competitors' YouTube channels

Visit your competitors' YouTube channels directly to study what topics they cover, how they package each video, and which videos perform.

Pick three to five channels similar in size to yours that cover topics in your space. If you’re covering topics related to the topic “home studio setup,” you're looking for content-creation gear channels at your subscriber level.

For each channel, look at:

  1. What topics they cover. Scan their video grid sorted by most popular. The titles and view counts tell you which of your candidate topics they've already addressed and which they haven't.
  2. How they package each video. Look at titles, thumbnails, video formats (talking head, screen capture, walkthrough, etc.), and angles (beginner intro, mistake-fixer, comparison, etc). Note the patterns you see at the top of their popular list.
  3. Which videos significantly overperform. A video with five to 10 times the average view count of the channel's other videos is signaling something. Usually it means the topic, the angle, or the packaging tapped into something worth paying attention to.

You can also check competitors' tags to see which keywords they're targeting.Tags have minimal impact on search results, but they reveal how other creators think about a topic.

Finally, note what's missing across the channels you've reviewed:

These gaps are your highest-value opportunities.

Use YouTube keyword research tools

Use YouTube keyword research tools to validate the specific topics you’ve gathered so far.

The Keyword Analytics for YouTube app pulls real YouTube search data and tells you which of your keyword ideas have meaningful demand.

To use it, click "Get started" under "Keywords Research,” enter one of your topic ideas (e.g., "budget home studio setup"), and choose your country.

Keyword Analytics for YouTube with "budget home studio setup" entered and "United States" selected as the location.

Review the results and look at "Search Volume" and "Competitive rate." Choose to display the data for the last day, week, or month data depending on how time-sensitive your topic is.

For each keyword, record four things in your scoring spreadsheet:

Next, use the Keyword Magic Tool to confirm which of your candidates also trigger video SERP features (video carousels, featured videos, and video results) in Google. Because a topic that ranks on YouTube and in Google's video features compounds your reach.

To check whether a candidate topic triggers video features, enter a topic into the Keyword Magic Tool, click "Advanced filters" then "Any” under “SERP Features." Select the boxes next to "Video," "Featured video," and "Video carousel," then click "Apply."

Applying a filter on the Keyword Magic Tool to only show keywords triggering a video, featured video, or video carousel on the SERP.

If the topic appears in this filtered list, Google currently shows video results for it.

When a candidate shows strong demand in the Top Keywords tab in Keyword Analytics for YouTube and also triggers video SERP features in Google, that's strong support for putting it into production. Add “yes” or “no” in column D (Google video SERP) in your scoring sheet.

Score and prioritize video opportunities

Once you have a list of validated topics, prioritize them with our YouTube keyword scorer that considers each topic’s demand, competition, channel fit, format fit, business value, and urgency.

Here’s how to use the YouTube video keyword scoring spreadsheet:

Step 1: Complete the ‘Scorer’ tab

Complete the “Scorer” tab by entering the terms you want to focus on from your list of candidates and scoring them. For reference, here’s how to score each factor (factor weights are specified in parentheses):

“Demand” and “Business value” are weighted the heaviest because volume and payoff are the two things you cannot manufacture later.

“Channel fit,” “Format fit,” and “Urgency” are weighted less because they’re negotiable. You can stretch your channel a little, learn a new format, or wait out a seasonal cycle.

Step 2. Review the ‘Score’ and ‘Recommendation’ columns

The YouTube keyword scorer spreadsheet automatically calculates a score and recommendation for each topic:

The “Recommendation” cell is color-coded, so you can easily scan the list.

Use AI to expand video angles for each topic

Once you have a list of validated topics, use a large language model tool (LLM) to generate two or three specific video angles and format suggestions for each one.

Open Claude, ChatGPT, or another LLM. For each validated topic, paste this prompt:

I run a YouTube channel about [your channel’s topic]. I've validated the topic "[your topic]" with search volume [specific search volume] and competitive rate [specific competitive rate].

Suggest three distinct video angles for this topic that are designed to appeal to YouTube's algorithm (which is based on topical relevance, engagement, and quality) and viewer psychology (curiosity, specificity, value frames).

For each angle:

Run the prompt for each validated topic to get a few packaging-ready video ideas you can compare side by side.

A few practical notes:

Treat the AI output as a brainstorming partner. It expands your shortlist of validated topics into a fuller set of producible video ideas. You still need to ultimately pick which ones make it on the calendar.

How to use your YouTube keyword research

To use your YouTube keyword research, apply the insights as relevance signals across each element of the video to strengthen your ability to perform well both in YouTube SEO and in Google's video features.

Use keywords in video elements

Use keywords in specific elements to signal what your video covers and who it serves.

Titles

Your video title tells YouTube what the video is about and tells viewers whether to click.

Whether to use your primary keyword in the title depends on the topic. Search YouTube for the topic and study the top results.

If the top-ranking videos for a given keyword all include the exact phrase, do the same. If the leaders use hooks (tested counts, years, warnings, or contrasts) instead, match that pattern.

Here are a few suggestions:

Descriptions

Your video description does two jobs: It gives YouTube text to classify the video for related searches and previews the content for viewers deciding whether to click.

When writing your description:

Hashtags

Use two or three relevant hashtags to help your video appear in YouTube's topic-based searches and feeds.

Hashtags will show up like this when your video is published:

Tags

Tags have minimal impact on rankings, but they help YouTube categorize misspellings and edge variations of your keyword.

Here are some tips for YouTube tags:

Chapters

Chapters break the video into navigable sections that can be separately surfaced as results inside YouTube and Google.

Plus, adding chapters to your videos helps users find the information that’s most relevant to them. Here are some best practices:

Optimize your videos for Google and AI Overviews

You don’t have to do anything special to make your YouTube videos eligible for Google's video features and AI Overviews, but you can increase your chances of showing up if you focus on basic video SEO practices like including a clear title, a thorough description, chapters with timestamps, and a clean transcript.

Here’s what matters:

A video result on Google with the "10 key moments in this video" section highlighted.

Add keywords to your playlist titles and descriptions

Adding keywords to playlist titles and descriptions helps your playlists show in search results and as recommendations.

Here are some tips:

Optimize your channel with keywords

Optimizing your channel with keywords helps YouTube understand your channel as a whole, which influences your recommendations and search visibility.

Start with the channel description. Open YouTube Studio and go to “Customization” and select “Profile.”

Write a description that names your channel’s main topic and what viewers will get from subscribing. Include your primary topic keywords in the first one to two sentences. Those first few lines appear under your channel name in search results.

Then add five to 10 keywords in the channel keywords field by going to “Settings” > “Channel” > “Basic info.” Choose terms that best represent your main topics..

YouTube keyword research FAQs

Here are quick answers to the questions readers ask most about YouTube keyword research.

What are the best keywords for YouTube?

The best keywords for YouTube have meaningful search volume, manageable competition for your channel size, and point to a video you can produce well. High volume alone doesn't make a keyword good if your channel can't credibly own the topic.

How many keywords should you use for YouTube videos?

Use one primary keyword per video, plus some supporting keywords for YouTube videos spread across the title, description, hashtags, tags, and chapters.

The primary keyword represents the core topic. Supporting keywords cover phrase variations and adjacent topics, so YouTube can match the video to a wider set of queries.

How do I identify low-competition keywords on YouTube?

To identify low-competition keywords on YouTube, use the Keyword Analytics for YouTube app to look for terms with low “Competitive rate” scores that still have meaningful search volume.

Cross-check any candidate against the actual YouTube search results. If the top results are all from massive channels with millions of subscribers, the keyword is harder than the score suggests.
