SpyFu
Your competitors test keywords, run ads, and build search strategies with real budgets every day. That's free market research — if you know where to look. SpyFu makes all of it visible. Every keyword they rank for. Every ad they've ever run. Every dollar they spend. 15+ years of history, updated daily. Twenty years ago, SpyFu's founder Mike Roberts needed competitive search data that didn't exist yet. So he built it. First to market, and two decades later, SpyFu has the deepest competitive search dataset available: on average, 2x more organic keywords and 20x more paid data than alternatives, with the most complete PPC intelligence anywhere. SpyFu GPT is the first SEO platform natively inside ChatGPT. Ask competitive questions in plain English and get answers grounded in real search data — not hallucinated numbers. Full access starts at $39/mo. No feature walls. We also built RivalFlow — powered by SpyFu's data. Ranking today isn't just about page one. It's about having the content that AI and LLMs trust enough to cite, recommend, and surface to their users. RivalFlow finds the exact content gaps between your pages and the ones outranking you, then gives you the copy to close them — so your content becomes the answer, wherever the question gets asked. Follow SpyFu for competitive intelligence and the data-backed strategies that help you decide what to do next.
