Astro SEO

Audits and improves the SEO setup of an Astro site against the full stack described in Astro SEO: the definitive guide. The skill covers nine areas — technical foundation, structured data, content, site structure, performance, sitemaps and indexing, agent discovery, redirects, and analytics — and produces drop-in code for anything missing or weak.

The opinionated spine of this skill is @jdevalk/astro-seo-graph. Most of the fixes route through it. If the project doesn't use it yet, installing it is the first recommendation.

Code recipes live in AGENTS.md — read it when you need to implement a specific fix. This file has the workflow and audit checklist.

Workflow

1. Detect the project — confirm this is an Astro site and understand its shape.
2. Audit — score nine categories and produce actionable findings.
3. Improve — generate or modify files to close the gaps. Recipes are in AGENTS.md.
4. Metadata pass — invoke metadata-check on every short string the skill generated (titles, descriptions, schema description fields, FAQ answers, frontmatter excerpts).
5. Verify — run the build, check validations pass, remind the user about non-file tasks (Search Console, Bing Webmaster Tools, IndexNow key verification).
