How is this different from SEO tools? GEO vs SEO
Traditional SEO optimizes for Google crawlers. AgentCheck focuses on GEO (Generative Engine Optimization) and AEO (AI Engine Optimization) — optimizing for AI agents like ChatGPT, Claude, Gemini, and Perplexity which read structured data, llms.txt, ai.txt, and machine-readable formats that traditional search crawlers ignore. LLM SEO is the future of website visibility.
Which AI agents does this cover?
ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Perplexity, and any AI agent following standard web protocols.
