I have a paid competitor monitoring tool for SaaS founders. One of its features shows what keywords any website ranks for on Google. I pulled it out and made a free version anyone can use. Paste any URL and in seconds you get their top 10 ranking keywords with position, volume, and difficulty score. Real data, no guesses. No account, no credit card.
