Tutorial and review comment sections are full of "how do I…", "this broke for me", and "what tool does this" - high-intent questions hiding under view counts. Needle searches YouTube comments alongside Reddit, Hacker News, and Stack Overflow and ranks by buying intent so you find motivated viewers, not just popular videos.
Search your category plus how-to and comparison terms - that is where buyers ask for tools.
View count ≠ demand. Intent scoring prioritizes problems and "what do you use" over "great video!".
Add genuine value in-thread. Needle finds the comments; you keep the relationship.
