How to get video ideas from YouTube comments
Why your comment section is better than any keyword tool
Most creators struggle with content ideation because they rely on generic SEO keyword scrapers. These tools tell you search volume from 6 months ago, but they miss real-time human curiosity and emerging pain points.
Your YouTube comment section represents viewers who have already watched your content, identified what was missing, and typed out exactly what they want to see next.
A regular comment-mining pass turns that into a queue of ideas that arrived with demand already attached.
The 4 types of comments that signal viral video potential
Not every comment makes a good video. Look specifically for these 4 high-signal comment archetypes:
| Comment Archetype | Example Comment | Video Idea Translation |
|---|---|---|
| 1. The "What About..." Objection | "Great breakdown, but how does this work if you have $0 budget?" | Title: "How to [Goal] with ZERO Budget (Step-by-step for Beginners)" |
| 2. The Missing Step Confusion | "I got stuck at minute 4:20 trying to connect the API." | Title: "How to Connect [Tool] (Fix the Most Common Setup Error)" |
| 3. The Tool Comparison Request | "How does this compare to [Competitor Tool]?" | Title: "[Tool A] vs [Tool B]: An Honest Comparison (Which is Better?)" |
| 4. The "Can You Do a Video On..." Demand | "Please make a full tutorial on how you organized that dashboard!" | Title: "My Complete [System] Setup Walkthrough (Free Template Inside)" |
The 3-Step comment-mining workflow
Follow this weekly process to organize comment ideas into an actionable production queue:
[ Step 1: Filter YouTube Studio Comments for "Contains Questions" ]

[ Step 2: Log Recurring Questions into a Notion/Airtable Idea Board ]

[ Step 3: Group Ideas by Theme & Select the Top 3 for Next Month's Shoot ]Step 1: filter for questions weekly
Fifteen minutes in YouTube Studio, Comments. Stack the contains questions filter with I haven't responded and you have the raw list. Some of it needs a reply rather than a video, and sorting between those is worth doing deliberately.
Step 2: sort by likes
This is the only real demand signal in the room. One person asking is one person. A question with fifteen likes is fifteen people who did not want to type it themselves, and there are always more who did not click either.
Step 3: draft titles using viewer vocabulary
Write your video titles using the exact words your commenters used rather than complex industry jargon. This dramatically increases Click-Through Rate (CTR) because searchers see their exact thoughts reflected in your title.
Competitor comment mining: finding gaps in other channels
You don't have to limit comment mining to your own channel. One of the best tactics is analyzing comments on top competitor videos in your niche:
Your own comments are limited by your own audience size. The comments under the biggest videos on your topic are not.
- Find the three most-viewed videos published on your subject in the last year.
- Read their comment sections for complaints rather than praise. "He skipped the hardest part at 6:10." "This is out of date." "Doesn't work on Mac." Each one is a video a proven audience has already asked for and not received.
- Searching the thread for
skipped,outdatedanddoesn't workgets you there faster than scrolling, and it reads the whole comment section rather than the part your browser has loaded. - Make the version that covers the step they skipped.
This is the most reliable source of ideas in the whole method, because the demand has been demonstrated on someone else's traffic before you spend a day filming.
How to validate demand and capture leads with ReplyTide
Once you produce a video based on a viewer's comment idea, close the loop to capture high-intent leads:
- Credit the Commenter: In your video intro, show a screenshot of the comment and say: "John asked how to set up this workflow, so in today's video, I built the entire template for you."
- Offer the Solution as a Lead Magnet: Tell viewers: "Comment 'TEMPLATE' below and I'll send you the exact file I built for John."
- Automate the handout with ReplyTide: comment-driven videos almost always come with an artefact people will ask for, and the reply goes out on its own to everyone who types the word. Put the same link in the description so nobody has to comment for it. Otherwise the reward for a well-targeted video is four hundred people asking you for the file one at a time.
Once a quarter, do it properly
The weekly pass only sees recent comments. Every few months, export the comments from your ten most-watched videos, sort by like count and read the top hundred rows. Patterns show up across videos that are invisible within one: the same confusion under four different tutorials is a gap in how you explain the topic, not a flaw in one video.
If the export is large, hand it to an AI assistant and ask for recurring questions with counts and quotes, then verify a few of the quotes actually exist.
Common questions
How many comments do I need before this works?
Twenty or thirty per video is enough to spot repetition. Below that, mine the comment sections of larger channels covering your topic. The questions there are the same questions, and nothing stops you reading them.
Should I reply to the original commenter when the video goes live?
Yes, and reply on their original comment rather than starting fresh. They get a notification, they are already interested, and the video gets an engaged viewer in its first hour. It costs a sentence.
What is the best tool to organize video ideas?
Notion, Trello, and Airtable are the most popular free platforms to organize comment screenshots and categorize them into Pre-Production, Filming, and Editing stages.
