SpyFu

SpyFu is a competitive research tool for search marketing that reveals the keywords businesses buy on Google Ads and the terms they rank for organically. It archives years of historical data on domains, ad copy, and keyword positions.

Aimed at PPC managers, SEO specialists, and agencies, it helps users study rivals in detail. People can download a competitor's most profitable keywords, track ranking history, review past ad variations, and estimate advertising budgets to shape their own campaigns.

Founded in Scottsdale and bootstrapped without outside funding, SpyFu is known for a flat-rate approach that grants generous data access on simple monthly plans rather than charging per query. This one-price model sets it apart from tools that meter usage through credits.
