Cortex is AI-powered, expert-managed search marketing intelligence: an optimization engine trained on a 1.5M-passage corpus of platform-published best practices, refined by 50,000+ decisions and their attributed outcomes. It runs a continuous retrieve, analyze, decide, act, and measure loop across SEO, GEO, CRO, and PPC, covering Google Ads, Meta, Amazon, Microsoft, TikTok, and the AI channels (ChatGPT, Gemini, Perplexity, Claude), and every recommendation traces back to a documented source.
