SpyFu
Competitive IntelligenceTestedCompetitor keywords, ad history, ranking gaps, domain strength, and PPC intelligence from SpyFu's 18+ years of search data.
SpyFu is the competitive intelligence backbone of Agentcy. It draws on 18+ years of search data to reveal exactly what your competitors are doing in organic search and paid advertising — which keywords they rank for, what Google Ads they run, how their rankings have changed, and where the gaps are between your domain and theirs.
Ask questions the way you think about competitive strategy — "Who are my top SEO competitors?" or "What Google Ads is this domain running?" — and Agentcy decomposes your question into the right API calls across 14 operations covering domain stats, keyword research, ad history, competitor analysis, and ranking trends. Results are synthesized into actionable intelligence, not raw data tables.
SpyFu is a BYOK (Bring Your Own Key) service. You provide your SpyFu API credentials, and Agentcy handles the rest — intelligent request decomposition, cost-aware pagination, rate limit management, and cross-source correlation with your other marketing data.
