SpyFu is a competitive search-intelligence platform that lets marketers, SEO consultants, and PPC managers reverse-engineer competitors' Google organic and paid search strategies.
Vertical: competitive SEO / PPC intelligence (horizontal marketing tooling, not industry-specific). In-house marketers and agency PPC managers pull a competitor domain to see every keyword that competitor has bought on Google, every ad headline and description variant, estimated monthly ad spend, and which keywords have been profitable enough to keep bidding on for years.
SpyFu is well-known inside the SEO/PPC community and has been around since 2005, but its install base is materially smaller than Semrush (~117k paying customers) or Ahrefs.
No. SpyFu's value is in surfacing scraped public-web competitive intelligence (other people's Google Ads keywords, ad copy, organic rankings, backlinks) rather than storing the customer's own system-of-record data.
Founded 2005 in Scottsdale, Arizona (originally as 'GoogSpy', renamed to SpyFu in 2007) by Mike Roberts. Bootstrapped and privately held, no significant venture funding disclosed.
Per-row pricing on premium endpoints (Ad History, Ranking History, Top Pages) burns through the $40-$100 included credits quickly on any non-trivial competitor research workload. API access is gated to Pro+AI and Team/Agency tiers, the entry-level $39 Basic plan does not include any API access. Full sourced list under Sources below.
Common alternatives include Semrush, Ahrefs, Similarweb, Moz Pro, SE Ranking, Serpstat. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
