 Zero-dependency SEO toolkit for Astro and static sites. Generate `llms.txt`, `sitemap.xml` and `robots.txt`, build JSON-LD schema, and push URL updates via IndexNow — with plain Node 18+, no installs. Built for 2026 search: AI answers (ChatGPT, Perplexity, AI Overviews) cite sites that are machine-readable and quotable, and classic search (Google, Bing) still runs on sitemaps and schema.
