A simple way to start is to check where people are already asking questions, like theyve been doing for a while. Try Google Autocomplete, the “People Also Ask” section, plus places such as Reddit, Quora, and niche forums. After that, confirm the idea with tools such as Ahrefs, SEMrush, or Google Keyword Planner. Aim for long tail keywords that show clear search intent. Then look at the top 10 results, and if they look thin or outdated then you probably stumbled into a real opportunity.
