YouTube keyword research: how to find what people search for

YouTube is the second biggest search engine in the world, and it works differently from Google. People search for tutorials, reviews, comparisons and "watch me do it" content. If your video titles match those searches, YouTube can surface them for years. If they don't, even great videos get buried.

How YouTube search differs from Google

• Different phrasing. On Google someone types "best running shoes 2026". On YouTube they type "running shoes review" or "nike vs adidas running shoes".
• Visual and practical topics win. How-tos, unboxings, tutorials, comparisons and "day in the life" content.
• Click-through and watch time matter a lot. A good keyword gets you shown; your title and thumbnail get you clicked.

So your research should use YouTube's own data, not just Google's.

Step 1: collect YouTube's autocomplete suggestions

YouTube's search box suggests what people search on YouTube specifically. That's your best free source of video ideas.

1. Open the keyword ideas tool and switch the source to YouTube.
2. Enter your topic, like "home workout" or "excel".
3. Browse the Questions group for tutorial ideas ("how to…") and the Comparisons group for versus videos.
4. Sort by most popular and export the best ideas as a CSV.

Step 2: check what already ranks

Search each idea on YouTube and look at the top results:

• Are the top videos old? Outdated videos on a popular search are an opening.
• Are they from small channels? Then a newcomer can compete.
• What's the format? Short and punchy, or long and detailed? Match what's working, then make it better.

Step 3: use YouTube Studio's research tools

If you have a channel, YouTube Studio's analytics include a Research section showing what your audience and viewers in general are searching for, including searches where there aren't many good videos yet. These "content gap" searches are pure gold for small channels.

Step 4: put the keyword in the right places

• Title: include the main phrase naturally, ideally near the start. Keep it under about 60 characters so it isn't cut off.
• Description: use the keyword and related phrases in the first two lines, then add a fuller summary and chapters.
• Chapters: timestamps with descriptive titles help viewers and can appear in search.
• Spoken words: YouTube transcribes your video, so say the topic out loud in the first minute.

Tags matter much less than they used to. Focus on title, description and the video itself.

Step 5: write a title people want to click

Ranking only gets you shown. The title and thumbnail decide whether anyone clicks. Strong YouTube titles are specific and promise an outcome: "I tried 5 cold email templates for 30 days" beats "cold email tips".

Run your title through the headline analyzer before publishing. It flags vague, overlong or clickbait-sounding titles. Then check that your thumbnail works at YouTube's 1280 × 720 size with the image resizer.

Frequently asked questions

How do I find keywords for YouTube for free?

Use YouTube's own autocomplete suggestions, which the mktbox keyword ideas tool collects when you switch the source to YouTube, plus the Research section in YouTube Studio.

Do tags still matter on YouTube?

Very little. YouTube relies mostly on your title, description, spoken words and how viewers respond. Use a few tags for common misspellings and leave it there.

How long should a YouTube title be?

Aim for under about 60 characters so it isn't cut off in search results and on phones, with the main keyword near the start.
