Keyword research for YouTube isn’t about gaming an algorithm. It answers one question: how do the people I want to reach describe what they’re looking for? Get that right and your titles, descriptions and topics line up with real demand.
This method uses only free tools and data you can check yourself.
Start here: the YouTube keyword brainstormer expands a topic into search phrases grouped by intent, with one-click checks on YouTube and Google Trends. It doesn’t show search volumes, because we don’t have YouTube’s data and won’t invent numbers.
Step 1: Brainstorm broadly
Enter your topic and, if they matter, your audience, location and the tools or products involved. The brainstormer returns phrases in groups:
- Learn: “video editing for beginners”, “video editing step by step”
- Questions: “how long does video editing take”, “what do you need for video editing”
- Compare and choose: “best video editing”, “capcut vs premiere pro”
- Problems and mistakes: “video editing mistakes beginners make”
- Ideas and inspiration: “video editing ideas”
- Audience, place and time: “video editing for youtubers”, “video editing in south africa”
Untick anything that doesn’t fit your topic, since some combinations won’t make sense. Download the rest as a CSV to work through.
Step 2: Check each phrase on YouTube
For each promising phrase, click YouTube ↗ (or type it into YouTube search yourself) and look at three things:
- Does it auto-complete? Type the first few words slowly. YouTube’s suggestions reflect what people search for, so a phrase that appears there is a good sign.
- What’s already there? Are the top results exactly on this topic, or only loosely related? Loose matches suggest a gap you could fill.
- How old and how good are they? Old, outdated or thin videos are an opportunity. A wall of excellent recent videos from big channels means you need a sharper angle.
Step 3: Compare interest in Google Trends
Select up to five phrases in the brainstormer and click Compare selected on Google Trends. It opens with the YouTube Search filter applied. You’ll see:
- which phrasing is more common, e.g. “meal prep” vs “batch cooking”
- whether interest is seasonal (braai content in summer, tax content near deadlines)
- where interest comes from, if you set a region
Trends shows relative interest, not absolute numbers. Use it to compare, not to forecast views.
Step 4: Use YouTube Studio’s Research tab
If you have a channel, open YouTube Studio → Analytics → Research. It shows what your viewers search for on YouTube and what people search for across YouTube on a topic. For an existing channel, this is the most relevant data you’ll find, because it’s about your audience.
Step 5: Choose with relevance first
Pick a primary phrase for each video using these questions, in this order:
- Does my video genuinely answer it? If not, it’s the wrong keyword.
- Can I make something better or different from what’s already ranking?
- Is there evidence people search for it? Auto-complete, Trends or the Research tab.
Small channels usually do better with specific phrases that match their video exactly than with broad, crowded ones.
Step 6: Use the keyword naturally
- Title: put the phrase near the start. Click “Write titles for the first selected” in the brainstormer to open the title generator with it as the keyword.
- Description: use it in the first sentence or two, and naturally after that. The description generator structures the rest.
- In the video: say it early. YouTube can generate captions from speech, so what you say matters too.
Don’t stuff the same phrase everywhere. Write for the viewer first.
What this won’t do
Keyword research improves your odds of being found by the right people. It doesn’t guarantee views or rankings, and nobody outside YouTube knows exactly how its recommendations work. The most reliable signal is your own analytics over time: what gets clicked, watched and shared.
