YouTube Comments Market Research: Find What Buyers Want
YouTube comments market research means reading the comments under videos your buyers watch to learn their problems in their own words. Pick videos about the problem, not about your product idea, sort comments by Top, and copy every comment that names a pain, a failed fix, a price or a wish. Then count which pains repeat across different videos and channels. A pain that shows up under many videos, in strong words, is worth testing. One loud comment is not.
Why use YouTube comments for market research?
Because people write them unprompted. Nobody asked them a survey question, so they describe the problem the way they live it. That gives you three things a survey rarely does:
- The buyer’s own words. The phrases you later put in a headline, an ad or a waitlist page.
- Failed fixes. “I tried X and it still…” tells you what the market already sells and where it falls short.
- Intensity. Long, specific, angry or grateful comments show how much the problem costs the person.
YouTube also adds something Reddit doesn’t: view counts. A video with many views on a problem tells you how many people went looking for help with it. Reddit threads show the pain in depth; YouTube shows the reach. Use both. How to find pain points on Reddit covers the Reddit half.
Which YouTube videos should you read comments on?
Pick videos where your buyer is the viewer, and where the problem is the topic:
| Video type | What its comments tell you | Example search |
|---|---|---|
| How-to and tutorials | Where people get stuck, what’s still unclear | “how to [do the task]” |
| Reviews of competitors | What buyers like, what they’d change, prices they paid | “[competitor] review” |
| “I tried” and “after 1 year” videos | Failed fixes and real results over time | “[product type] after 1 year” |
| Rants and “stop doing this” videos | The strongest pains, in the strongest words | “[task] is so frustrating” |
| Comparisons | The criteria buyers actually use to choose | “[option A] vs [option B]” |
Start with 5 to 10 videos from different channels. One channel’s comment section reflects that creator’s audience, not the market. Recent videos matter too: a pain from comments five years ago may already be solved.
The YouTube search box helps you find the right videos. Type the start of the problem and read the suggestions: they come from what people search, so they show how buyers phrase it.
What should you copy from the comments?
Copy comments, not your summary of them. Keep the exact words, because the exact words are what you’ll test later. For each one, note:
- The pain. What goes wrong, in their words.
- The context. Who they are, when it happens, what they were trying to do.
- The failed fix. Any product, method or service they tried.
- Money. Any price, budget or “I’d pay for…” line.
- Likes and replies. A comment with many likes speaks for more people than its author.
A spreadsheet with one row per comment works well. Add a column for the video and the channel so you can count across sources.
How do you rank the pains you find?
Group the comments by pain, then score each group. A simple way:
| Signal | Strong | Weak |
|---|---|---|
| Frequency | Shows up across many videos and channels | Only under one video |
| Intensity | Specific, emotional, describes real cost | Vague (“this is annoying”) |
| Failed fixes | People tried paid products and still complain | Nobody tried anything |
| Money | Prices, budgets, “take my money” | No talk of paying |
| Agreement | Many likes, replies saying “same” | No reaction |
The pains that score high on frequency, intensity and money are the ones to build around. Customer pain points explains the ranking in more depth.
What are the common mistakes with YouTube comment research?
- Reading only one channel. Its audience may not be your buyer.
- Reading only the newest comments. Sort by Top for the comments viewers agreed with.
- Counting creator fans as buyers. “Great video!” tells you about the creator, not the problem.
- Summarizing too early. Paraphrase loses the words that sell.
- Treating comments as proof of payment. Comments show pain and reach. They don’t show that people pay. Check that with competitors, prices and live ads, as in market research for a product.
Where does YouTube fit in idea validation?
YouTube is one source among several. It answers “is the pain real, and do many people look for help?” It doesn’t answer “do people already pay to fix it?” For that, look at competitors, active ads in the Facebook Ad Library and what buyers pay. Put it all together and you have the evidence behind a business idea validation.
How does Vettoz use YouTube?
Vettoz is an idea researcher that works inside Claude, ChatGPT or Cursor. When you check an idea, he searches YouTube for your keywords and collects the videos and Shorts with their views, channels and dates, plus the YouTube search box suggestions. He reads Reddit, X, TikTok, active Meta ads, Google, and TikTok Shop or the App Store alongside it. Then he scores the idea on pain, demand, pay, room and reach, with a GO, TEST or RETHINK verdict and the evidence behind each number.
He doesn’t read YouTube comments. Use the videos he finds as your shortlist and read their top comments yourself with the method above.

FAQ
Is YouTube comment research free?
Yes. Reading comments costs only time. Tools that export comments save time on big videos, but a manual read of 5 to 10 videos is enough to start.
How many comments should I read?
Read until new comments stop adding new pains. Then read one more video to make sure.
Are YouTube comments better than Reddit for market research?
Neither is better. Reddit gives depth: long posts and discussions. YouTube gives reach: view counts show how many people looked for help. Use both and trust the pains that show up in each.
Can I use AI to analyze YouTube comments?
Yes. Paste the comments into ChatGPT or Claude and ask it to group them by pain and quote the exact words. Check the groups against the comments yourself, because a model can merge pains that buyers see as different.
What should I do after the research?
Write the strongest pain as a promise, put it on a page with a price and test it. See product validation and the fake door test.
