SpyFu (spyfu.com) is a competitive SEO and PPC intelligence platform that specialises in revealing what keywords competitors are ranking for organically and bidding on in Google Ads — including historical data going back over a decade. Founded in 2006 and based in Phoenix, Arizona, SpyFu has built one of the largest databases of search marketing intelligence, covering millions of domains and billions of keywords across Google search results and advertising auctions.
SpyFu's core value proposition is competitor transparency: by entering any competitor's domain, marketers can see every organic keyword that domain has ever ranked for, every Google Ads keyword they have ever bid on, their estimated ad spend, their most successful ad copy, and their SEO backlink profile. This intelligence helps marketers identify keyword gaps — terms competitors rank for that they do not — prioritise SEO content topics with proven demand, and reverse-engineer PPC campaigns to understand what messaging and bidding strategies have worked for competitors over time.
How SpyFu Works
Users enter a competitor's domain into SpyFu's search bar to see a comprehensive overview of that domain's search marketing profile — organic keyword rankings, estimated organic traffic, paid keyword history, estimated Google Ads spend, top-performing ad copy, and backlink data. SpyFu's Kombat tool allows side-by-side keyword comparison between multiple domains, showing which keywords are shared across competitors and which represent exclusive opportunities. The keyword research tool surfaces related keyword suggestions with difficulty scores, monthly search volume, and cost-per-click estimates. Rank tracking monitors positions for a custom list of keywords over time with daily updates and SERP feature tracking.

Who Should Use SpyFu?
SpyFu is well suited to SEO professionals, PPC managers, digital marketing agencies, and content strategists who rely heavily on competitive intelligence to inform their keyword targeting and campaign strategy. Its historical data depth — tracking competitor keyword activity over many years — is a significant advantage over tools that only show current rankings. The Basic plan at $29/month (annual) is one of the most affordable entry points for unlimited competitor domain research in the SEO tool market. SpyFu is less suited to users who need enterprise-grade technical SEO auditing, large-scale crawl data, or comprehensive content gap analysis — tools like Semrush or Ahrefs offer broader coverage for those use cases, albeit at higher price points.
Frequently Asked Questions
What is SpyFu used for?
SpyFu is a competitive SEO and PPC intelligence tool used by digital marketers to research what keywords competitors rank for organically and bid on in Google Ads. It provides historical keyword data, ad copy intelligence, estimated competitor spend, backlink analysis, and rank tracking. Marketers use it to find keyword gaps, reverse-engineer competitor PPC campaigns, identify content opportunities, and monitor their own rankings against competitors over time.
How much does SpyFu cost?
SpyFu's Basic plan costs $39/month ($29/month billed annually), the Professional plan costs $59/month ($89/month annually — note the annual rate is higher for this tier, so monthly billing may be better value), and the Team plan costs $249/month ($187/month annually). The Basic annual plan at $29/month is particularly competitive for the amount of competitor research data it provides.
How does SpyFu compare to Semrush and Ahrefs?
SpyFu, Semrush, and Ahrefs all provide competitor keyword research and rank tracking, but differ in scope and price. SpyFu's strength is its historical PPC and organic keyword data depth and its affordability — the Basic plan at $29/month covers unlimited domain research that would cost significantly more on Semrush or Ahrefs. Semrush and Ahrefs offer broader toolsets including technical SEO auditing, content gap analysis, and larger backlink databases. SpyFu is the strongest choice when competitive PPC intelligence and keyword history are the primary needs; Semrush or Ahrefs are better for teams that also need deep technical SEO and content analytics.
Does SpyFu show Google Ads data?
Yes. SpyFu provides detailed Google Ads intelligence for any domain — including every keyword a domain has ever bid on, their estimated monthly ad spend, their top-performing ad copy, the landing pages those ads pointed to, and a history of how their PPC keyword coverage has changed over time. The AdWords Advisor feature uses this competitive data to recommend specific keywords to add or exclude from your own campaigns based on what has historically worked for competitors in your space.
How far back does SpyFu's historical data go?
SpyFu has been collecting search marketing data since 2006 and maintains one of the deepest historical keyword databases available for a tool at its price point. For many domains, users can see organic ranking history and paid keyword activity going back more than a decade. This long historical view is particularly useful for identifying which competitor keywords have driven sustained organic traffic over time versus short-term spikes, and for understanding how a competitor's PPC strategy has evolved across different market conditions.
