Most underperforming videos weren't poorly made: they were unwanted. Demand research is the habit of checking appetite before committing production time, and it takes about 30 minutes once you know the moves. Here's the complete check.
Signal 1: Outliers in adjacent topics
Find channels near your niche and look for videos outperforming their channel average by 3x or more: outliers prove viewers pulled that topic beyond the channel's normal reach. Three outliers around adjacent topics is strong evidence of appetite; zero outliers anywhere nearby is a warning.
Signal 2: What viewers ask for
Read the comments on the closest-performing videos and collect explicit requests: questions asked repeatedly, follow-ups begged for, complaints about what's missing. Viewers literally write your content briefs if you read systematically instead of scrolling.
- Repeated questions across multiple videos
- Requests for follow-ups, comparisons, or beginner versions
- Complaints that reveal an underserved angle
Signal 3: The freshness test
Demand alone isn't enough: you need an opening. Ask: can I cover this with a meaningfully different angle, better packaging, or deeper usefulness than what exists? If the top videos are years old and weak, that's opportunity. If they're recent and excellent, that's a wall.
Running the 30-minute check
Minutes 0–10: find and note three outliers. Minutes 10–20: harvest comments into a request list. Minutes 20–30: assess freshness and score the idea. Ideas that pass get filmed; ideas that fail get one sentence in a backlog explaining why: so future you doesn't re-research the same dead end.
