Google Trends

Google Free Beginner

Before you spend a weekend guessing, Google Trends gives you a real, free read on whether interest in your idea is rising, flat, or fading, and where in the country it's strongest. For a founder building outside the big startup hubs, the geography and city-level view is genuinely useful: you can see if demand clusters somewhere you can actually reach. Treat it as a demand signal to start from, not proof on its own.

• Search interest is shown 0 to 100 relative to its own peak, so it tells you direction and seasonality, not absolute customer counts.
• Filter by region and city, and by Web, YouTube, News, or Shopping, to see where and how people are actually looking.
• Compare a few terms side by side (yours plus close alternatives) to sanity-check which framing people search for.
