Pros and Cons
Advantages

Summary
SpyFu specializes in competitive intelligence, particularly for PPC advertising. The platform lets you see every keyword a competitor has bid on, every ad they have run, and their estimated monthly spend. The keyword history tool goes back over 18 years, showing how domains have evolved their organic and paid strategies. While it covers organic SEO, the real strength is in paid search competitive analysis.
Data Accuracy
SpyFu PPC data is highly accurate for US markets with detailed ad spend estimates and keyword bids. The organic keyword data is adequate but thinner than dedicated SEO tools like Ahrefs. Historical data going back 18+ years is unique and accurate for tracking competitive trends. International data coverage is improving but still lags behind the US dataset.
Features
The PPC competitor analysis tools are the standout features. Kombat compares keyword overlap between domains. Ad history shows every ad variation a competitor has tested. The SEO toolkit covers keyword research, backlink analysis, and rank tracking at a functional level. Custom reports aggregate data for client presentations.
Pricing
The Basic plan at $39 per month includes unlimited searches and data exports with all features accessible. The Professional plan at $79 adds API access, custom branded reporting, and additional data access. All plans include unlimited search results with no daily caps, which is unique in the category.
Ease of Use
The interface is straightforward with domain lookup as the primary entry point. Typing in any domain immediately surfaces organic keywords, paid keywords, and ad history. The layout is functional and data-focused rather than visually polished. Navigation is simple with clear tool separation.
Final Verdict
SpyFu is the best tool for PPC marketers and agencies who want deep competitive intelligence on paid search strategies. The 18-year keyword and ad history is unique and invaluable for understanding competitor evolution. For pure organic SEO work, dedicated tools like Ahrefs or Semrush are stronger. In 2026, SpyFu remains the go-to for competitive PPC research.
