aeo.js

Answer engine optimization packaged as an npm library, meant to make your pages discoverable by ChatGPT, Claude, Perplexity and other AI search engines. It generates llms.txt, robots.txt, a sitemap, JSON-LD and more, with setup guides for Astro, Next.js, Vite, Nuxt, Remix, SvelteKit, TanStack Start, Docusaurus, Eleventy, VitePress and Angular. One command prefills the config from package.json and generates everything. A check for any deployed address needs no install or config and returns a 0 to 100 GEO readiness score, an access matrix for 23 AI crawlers, average content citability and the top fixes, and it also runs in the browser. An MCP server lets Claude Code, Cursor or any MCP client audit and fix pages conversationally, with tools such as audit_url. Open source and free to use under its license.
