YouTube Comments Lead Generation: How to Find Buyers Under Tutorials and Reviews

Most people think of YouTube as a place to publish videos. But some of the most useful buying conversations on the platform happen below the video, in the comments.

When someone watches a review of three project management tools and then writes "which one would you pick for a team of four?", they are telling you exactly where they are in their decision. That is a buying signal, sitting in public. Here is where to look and how to reply without annoying the creator.

Why YouTube comments carry buying intent

People rarely watch a 15-minute comparison video for fun. They watch it because they are trying to decide something.

That makes certain types of videos especially useful to monitor:

Tutorials: "How to set up X" videos attract people who are stuck or just getting started.
Reviews and comparisons: "X vs Y" or "best tools for Z" videos attract people who are actively shopping.
Problem videos: "Why your lawn keeps dying" or "Fixing slow WordPress sites" attract people with a problem they want gone.
"Is it worth it?" videos: These pull in people close to a purchase who want reassurance.

The video gives you context for free: you know what the commenter was researching.

What buying signals look like in comments

YouTube comments are short and casual. Intent often shows up as a quick question rather than a detailed post.

Look for comments like:

"Which one should I buy if I mostly do..."
"Does this work for small businesses or just big teams?"
"I tried this and it didn't work for me. Any alternatives?"
"Is there something cheaper that does the same thing?"
"I'm in the same situation, what did you end up going with?"
"Can anyone recommend someone who does this in [city]?"

Skip praise for the creator, jokes, timestamps and off-topic arguments.

Replying under a comment versus posting a top-level comment

This is the most important choice on YouTube, and it changes how your reply is received.

Reply under a specific comment

When someone asks a direct question, reply to that comment. Your answer shows up in their notifications and sits right next to the question, so it reads as a response, not an announcement.

Use this when:

A specific person asked a question you can answer.
Someone described a problem you know how to solve.
Another commenter asked "what did you end up choosing?" and you have a real answer.

Example:

If you mostly edit short clips on a laptop, the second one in the video is usually lighter on older machines. The first one is better if you need multi-cam. What kind of videos are you making?

Post a top-level comment

A top-level comment speaks to everyone watching the video. It is visible to more people, but it is also more likely to look like advertising.

Use this sparingly, and only when:

You have something genuinely useful to add to the video itself, like a missing step or a correction.
The creator invites viewers to share their own experience.
Your comment would still be helpful if your business name were removed.

Example:

One thing worth adding for anyone doing this on an older house: check whether your panel has room for a new breaker before buying the charger. That was the part that surprised me.

A good rule of thumb: reply to people, and only comment to the video when you are adding to the video.

Channel etiquette

You are a guest in someone else's comment section. The creator built that audience, and they can delete your comment or block you in seconds.

Keep these habits:

Don't drop links in the first reply. Many channels hold link comments for review or hide them. Answer the question in plain text first.
Don't undercut the creator. If the video recommends a competitor, don't attack it. Add context about when another option might fit better.
Say who you are when it matters. If you are recommending your own product or service, say so. "I run a small cleaning company, so I'm biased, but..." builds more trust than pretending to be a neutral viewer.
Don't paste the same reply across videos. Creators and viewers notice, and it looks automated even when it isn't.
Be useful to the creator, too. A thoughtful answer improves their comment section.

How Reach Your Customer helps

Reach Your Customer monitors public YouTube comments, along with Reddit, X, Facebook groups, Instagram and LinkedIn, for buying intent. It scores each lead's fit and drafts a reply with AI that you review and approve. Nothing is posted without your approval.

If you use the optional browser extension (currently in alpha), approved replies can be posted from your own logged-in YouTube account, either as a comment on the video or as a reply under a specific comment. The extension caps replies at 5 per platform per day, waits at least 90 seconds between sends, and stops if it hits a login page, CAPTCHA or verification check. You can also run it in dry-run mode to see the reply typed out without posting.

FAQ

Is YouTube good for finding leads?

It can be, especially if your niche has tutorial, review, or comparison videos. Those comment sections are full of people actively researching a decision.

Should I include a link in my YouTube reply?

Usually not in the first reply. Answer the question in plain text. If the person asks for more detail, you can share a link then, or point them to your channel or profile.

How often should I comment on a single channel?

Keep it light. If your name shows up under every video on one channel, it looks like you are using their audience.
