What problem does it solve? Astro sites need correct meta tags, Open Graph previews, JSON-LD structured data, sitemaps, and canonical URLs to rank in search engines, but wiring all of this consistently across pages is repetitive and error-prone. ## Core Features & Use Cases - Reusable SEO Head Component: Centralizes title, description, Open Graph, Twitter Cards, favicons, and canonical URLs built with Astro.site. - JSON-LD Structured Data: Injects BlogPosting, WebSite, Organization, FAQ, and BreadcrumbList schemas via set:html to prevent XSS. - Sitemap, RSS & robots.txt: Configures @astrojs/sitemap and @astrojs/rss for indexing and content feeds. - International SEO & Performance: Adds hreflang with x-default for multilingual sites and optimizes Core Web Vitals (LCP, CLS, INP) using Astro's zero-JS output. - Use Case: When launching an Astro blog, generate a complete SEO setup — head component, BlogPosting schema, sitemap, RSS feed, and hreflang tags — in one pass. ## Quick Start Ask the agent to add complete SEO to your Astro site, including a reusable SEO head component, JSON-LD structured data, sitemap, RSS feed, and canonical URLs.
