Keyword research on YouTube is really demand research: finding topics that people are already looking for so your video meets an existing audience instead of hoping one appears. You can do most of it for free using YouTube itself.
Mine YouTube autocomplete
Type a seed phrase into the YouTube search bar and watch the suggestions. Those are real queries, ordered by popularity. Add a letter or a question word like how, why, or best to expand the list. This is the fastest free source of validated topics.
Study who already ranks
Search your topic and read the top results. High view counts on recent videos signal live demand. Note the angle each successful video takes, then find the gap: the question they did not answer, the audience they ignored, or the better explanation you can give.
Match intent to format
| Query type | What the viewer wants | Best format |
|---|---|---|
| how to ... | A clear method | Step-by-step tutorial |
| best ... / vs ... | A decision | Comparison or review |
| why ... / what is ... | Understanding | Explainer |

Check your own analytics
Your channel already tells you what works. In analytics, look at which search terms bring people to your videos and which existing videos pull search traffic. Make more on those proven themes. See YouTube analytics explained.
Turn keywords into a video
Once you have a validated phrase, turn it into angles with the video idea generator, write a title that includes the phrase naturally with the title generator, and build the rest of the page with the description generator.
