SpyFu is a competitive intelligence and keyword research tool that specialises in revealing your competitors' most profitable SEO and PPC strategies. Type in any competitor's domain and SpyFu shows you every keyword they've ever ranked for in Google, every ad they've run on Google Ads and how much they spend on paid search — giving you a complete picture of their digital marketing strategy going back years.
SpyFu's historical data is one of its biggest differentiators — while tools like Semrush and Ahrefs show current data, SpyFu lets you see 15+ years of keyword ranking history. This is invaluable for identifying evergreen keywords that consistently drive traffic, spotting seasonal patterns and understanding how a competitor's SEO strategy has evolved over time.
The tool is particularly popular with PPC advertisers who want to see exactly which ad copy and keywords their competitors are bidding on, and with SEO agencies who want to identify quick-win keyword opportunities by finding terms competitors rank for that their clients don't.
Who is SpyFu for?
PPC advertisers wanting to analyse competitor ad strategies, SEO professionals looking for keyword gap opportunities and digital marketing agencies conducting competitive audits. SpyFu is more affordable than Semrush or Ahrefs, making it a popular choice for freelancers and small agencies that need competitive intelligence without enterprise pricing.
