# Agentic SEO

> Agentic SEO across three problems: getting cited in AI answers (AI Overviews, ChatGPT search, Perplexity, Copilot), being legible to fetching agents (crawler user-agents, robots.txt, Content Signals, llms.txt, markdown negotiation), and being operable by acting agents (WebMCP, Web Bot Auth, x402, ACP/UCP).
> Covers: Agentic SEO as of 2026-11: how AI answer engines retrieve and cite (query fan-out, Google AI Overviews/AI Mode, ChatGPT search, Perplexity, Copilot, Claude), official controls and reporting, GEO research and vendor citation studies with methods, AI visibility measurement and tools, adversarial GEO and prompt injection; AI crawler and user-triggered fetcher user-agents, robots.txt for AI, Content Signals and IETF aipref, llms.txt evidence, markdown content negotiation, JS rendering by AI crawlers, structured data, bot-traffic reports; agent perception and site UX, WebMCP, discovery files (MCP server cards, ai-catalog, RFC 9727 api-catalog), Web Bot Auth, x402 and pay per crawl, agentic-commerce protocols (ACP, UCP, AP2, Visa TAP). Snapshot 2026-11-04.
> Not covered: The MCP protocol itself (see the mcp wiki); Shopify developer APIs (shopify wiki); paid search ads (google-ads / meta-ads); classic SEO beyond what official AI-search guidance says applies; primary HUMAN/DataDome/Akamai reports, the OpenAI help center and x402.org (not gathered); live rankings or citation tracking for a specific site — use a visibility tool or the web.
