Keyword Research for YouTube
YouTube keyword research is the process of finding the search terms viewers use on YouTube so you can choose video topics and optimize titles, descriptions, and tags around real demand.
What I’d do first
- Start with YouTube autocomplete and the alphabet trick to surface real search terms.
- Validate both demand and ranking potential before committing to a topic.
- Pick one primary keyword per video and optimize title, description, and tags around it.
- Match your video content to the search intent behind the keyword.
- Don't stuff unrelated keywords—focus on relevance over quantity.
The path I'd take
- Expand your list – Use YouTube autocomplete, Google Trends (set to YouTube Search), and competitor video titles to gather 10–20 potential keywords.
- Validate demand – Check if each keyword has search volume. For free, look at YouTube search suggestions and related videos. For more data, use a tool like VidIQ or TubeBuddy.
- Check ranking potential – Search the keyword on YouTube. Look at the top results: are they from channels your size? If all top videos have 100K+ views, the keyword may be too competitive.
- Pick one primary keyword – Choose the keyword that balances decent search demand with a realistic chance to rank. Keep 2–3 closely related terms as secondary keywords.
- Optimize your metadata – Put the primary keyword in your video title (ideally at the start), in the first 2 sentences of the description, and in the tags. Use secondary keywords naturally in the description.
- Match content to intent – Ensure your video actually answers the search query. If someone searches "how to edit video in Premiere Pro," don't make a review of Premiere Pro—make a tutorial.
Watch-outs
- Chasing high-volume keywords without checking competition – A keyword with 10K monthly searches is useless if you can't break into the top 10.
- Using many loosely related keywords – Stick to one primary term and a few tightly related phrases. Stuffing unrelated keywords confuses YouTube's algorithm.
- Optimizing metadata without matching the video – If your title says "How to bake a cake" but your video is a cake review, viewers will bounce and YouTube will stop recommending it.
- Treating tags as the main ranking signal – Tags are a minor signal. Focus on title, description, and content relevance first.
What I got wrong
I used to think more keywords = better. I'd cram 15 unrelated tags into every video and write descriptions stuffed with random phrases. It didn't help. YouTube's algorithm is smarter than that—it looks at whether the video actually satisfies the search. Now I pick one primary keyword, build the video around it, and only add a handful of closely related terms. My click-through rates and watch time both improved.
