Check the installed version against the latest on npm with npm view @jdevalk/astro-seo-graph version.

# Astro SEO
Audits and improves the SEO setup of an Astro site against the full stack described in [Astro SEO: the definitive guide](https://joost.blog/astro-seo-complete-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`](https://github.com/jdevalk/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).
---
## Phase 0: Detect the project
Confirm the basics before auditing:
- `astro.config.mjs` / `astro.config.ts` exists.
- `package.json` has `astro` as a dependency.
- **`site:` is set in `astro.config`** — canonicals, sitemaps, and OG image URLs all derive from this. If it's missing, empty, or `http://localhost`, flag it as a blocking issue before anything else. This is the single most common misconfiguration.
- Content collections in `src/content/` (or legacy `src/pages/` markdown).
- **Deployment target** — read `package.json`, `vercel.json`, `netlify.toml`, `wrangler.toml`, or `public/_headers` to determine the host. This drives redirect and header syntax in Phase 2.
- **Is `@jdevalk/astro-seo-graph` already installed?** If yes, record the version and which features are wired (grep for `<Seo`, `seoGraph(`, `createSchemaEndpoint`, `createSchemaMap`, `FuzzyRedirect`, `createIndexNowKeyRoute`, `createMarkdownEndpoint`, `createApiCatalog`, `gitLastmod`). **Check the installed version against the latest on npm** with `npm view @jdevalk/astro-seo-graph version`. If the project is behind, recommend an upgrade in Phase 2 before auditing feature gaps — the package ships new defaults and fixes regularly, and an outdated version is a plausible cause for any audit finding. Phase 2 branches on this.
- **Is the site multilingual?** Check for `i18n` in `astro.config` or multiple locale directories under `src/content/`. If yes, hreflang matters; if no, skip it.
Ask only what you can't detect. Don't ask the user what the site is about — read `astro.config.mjs` and the homepage content.
---
## Phase 1: Audit
Score each category out of 10. For each, give 2–4 specific findings that quote the actual code or config. Within each category, checks are tiered:
- **Must** — ship blockers. A failure here causes visible SEO regression.
- **Should** — standard practice. Skipping costs reach.
- **Nice** — forward-looking or situational. Useful but not baseline for every site.
Skip **Nice** checks for small personal blogs unless the user asks for the full treatment.
### 1. `<Seo>` component and head metadata (/10)
- **Must** — single component for all head metadata (not scattered across layouts).
- **Must** — `site:` in `astro.config` is set to the production origin.
- **Must** — canonical URLs derived from `site` config with tracking params stripped.
- **Must** — canonical omitted when `noindex` is true (per Google's recommendation).
- **Must** — fallback chain for missing SEO fields: `seo.title → title → siteName`; `seo.description → excerpt → first paragraph`. Pages with blank titles or descriptions are the most common symptom of a broken fallback.
- **Should** — `robots` meta includes `max-snippet:-1`, `max-image-preview:large`, `max-video-preview:-1`.
- **Should** — Twitter tags suppressed when they duplicate Open Graph (Twitter falls back automatically).
- **Should** — `hreflang` alternates present on multilingual sites. Skip if monolingual.
- **Nice** — uses `@jdevalk/astro-seo-graph`'s `<Seo>` component rather than hand-rolled. (Hand-rolled that covers everything above is fine; this skill nudges toward the package because it handles the fallback chain and robots rules by default.)
### 2. Structured data / JSON-LD graph (/10)
- Single flat `Article` object, or a linked `@graph` with multiple entities?
- Entities wired with `@id` references?
- `WebSite`, `Blog`/`WebPage`, `Person`/`Organization`, `BlogPosting`/`Article`, `BreadcrumbList`, `ImageObject` all present where relevant?
- Trust signals: `publishingPrinciples`, `copyrightHolder`, `copyrightYear`, `knowsAbout`, `SearchAction`?
- Validates in [Rich Results Test](https://search.google.com/test/rich-results) and [ClassySchema](https://classyschema.org/Visualisation)?
### 3. Content collections and SEO schema (/10)
- Content collections defined with Zod schemas?
- `seoSchema` from `@jdevalk/astro-seo-graph` enforcing title (5–120) and description (15–160) lengths?
- Required fields (`publishDate`, `title`, `excerpt`) enforced at build time?
- Markdown-stripped `articleBody` exposed in schema endpoints (up to 10K chars)?
### 4. Open Graph images (/10)
- Every page has an OG image, or many missing?
- 1200×675 (Google Discover minimum 1200px wide, 16:9 ratio)?
- Generated at build time via satori + sharp, or manual?
- JPEG (social platforms don't reliably support WebP/AVIF)?
- Route derives OG URL from the slug automatically?
- Every `<img>` in rendered HTML has an `alt` attribute (or `alt=""` / `role="presentation"` for decorative images)? `validateImageAlt` on `seoGraph()` catches this at build time in ≥ 1.1.0.
### 5. Sitemaps and indexing (/10)
- **Must** — `@astrojs/sitemap` installed, sitemap index reachable.
- **Must** — `robots.txt` references the sitemap index.
- **Must** — RSS feed exists (`@astrojs/rss`), advertised via `<link rel="alternate" type="application/rss+xml">`, contains full post content (not truncated excerpts).
- **Should** — split per-collection via `chunks` option (`sitemap-posts-0.xml`, etc.) — much easier to debug indexing in GSC.
- **Should** — `lastmod` populated from git commit timestamps, not frontmatter dates or CI file timestamps. `@jdevalk/astro-seo-graph` ≥ 1.4.0 exports `gitLastmod(filePath, { excludeCommits, depth })` for this — it returns the committer date of the most recent non-excluded commit that touched the file, or `null` if git is unavailable. Wire it into the sitemap `serialize` callback. If the codebase has a hand-rolled `execSync('git log ...')` helper, replace it with the package export — the export handles bulk-commit exclusion (imports, reformats) which a naïve `-1` lookup can't.
- **Should** — IndexNow integrated and submitting on each build, with key verification route at `/[key].txt`. ≥ 1.0.1 excludes `/404` from submissions by default. **Gate submission on the production host** (e.g. `process.env.CF_PAGES === '1' && CF_PAGES_BRANCH === 'main'`, `VERCEL_ENV === 'production'`, `CONTEXT === 'production'`). Unconditional submission pings the endpoint on every local `npm run build` and preview deploy with URLs the production host hasn't served yet, which gets the key marked invalid (403) and forces rotation.
### 6. Agent discovery (/10)
- **Should** — schema endpoints (`/schema/*.json`) exposing corpus-wide JSON-LD.
- **Should** — schema map (`/schemamap.xml`) listing all endpoints, with `Schemamap:` directive in `robots.txt`.
- **Should** — [`llms.txt`](https://llmstxt.org) at the site root listing pages (title + description) for LLM consumers. `@jdevalk/astro-seo-graph` ≥ 0.9.0 generates this via the `llmsTxt` integration option.
- **Should** — markdown-alternate URLs (`/blog/post.md` next to `/blog/post/`) serving clean markdown with YAML frontmatter for AI agents to consume without HTML parsing. `@jdevalk/astro-seo-graph` ≥ 1.2.0 ships `createMarkdownEndpoint` for the route and a `markdownAlternate: true` integration option that emits `<link rel="alternate" type="text/markdown">` on every page. ≥ 1.3.0 adds post-build verification: the integration walks the build output and strips any link whose `.md` target isn't on disk (with a `warn` per occurrence) — so a misconfigured endpoint surfaces as a build warning instead of a shipped 404. Pair with a Cloudflare Transform Rule (URL rewrite via `wildcard_replace`, no `Vary: Accept` header — CF strips custom Vary values) for content negotiation on `Accept: text/markdown` without needing SSR.
- **Should** — API catalog at `/.well-known/api-catalog` per [RFC 9727](https://www.rfc-editor.org/rfc/rfc9727). `@jdevalk/astro-seo-graph` ≥ 1.4.0 ships `createApiCatalog`, which auto-types schema endpoints to their `https://schema.org/<Type>` URLs and absolutizes paths against `siteUrl`. List the schema endpoints, schemamap, and any site-specific APIs (`/ask`, `/feed.xml`, etc.). The RFC is finalized so the format is stable; adoption is early but the cost is one route file.
- **Should** — Content Signals directive in `robots.txt` (e.g. `Content-Signal: ai-train=yes, search=yes, ai-input=yes`). Declares preferences for AI training, search grounding, and AI input use independently of crawl access. The spec is an [IETF draft](https://datatracker.ietf.org/doc/draft-romm-aipref-contentsignals/) and adoption is early, but it's one line in a file every site already has.
- **Should** — `Link` header on `/*` pointing to discovery files (sitemap, llms.txt, api-catalog, schemamap, and any MCP / A2A cards the site publishes). Agents reading response headers find them without parsing HTML. On Cloudflare Pages / Netlify this is `public/_headers`; on Vercel it's `vercel.json`.
- **Nice** — MCP server card at `/.well-known/mcp/server-card.json` ([SEP-1649](https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2127)) and / or A2A agent card at `/.well-known/agent-card.json` ([A2A protocol](https://a2a-protocol.org/)). Only relevant when the site actually exposes an MCP server or A2A agent. Both are static JSON files declaring the endpoint, capabilities, and skills. Skip otherwise.
- **Nice** — `<link rel="nlweb">` pointing to a conversational endpoint. NLWeb is early; the tag is one line and worth having, but it's not a scoring blocker in 2026.
- **Nice** — ARD ([Agentic Resource Discovery](https://agenticresourcediscovery.org/)) catalog at `/.well-known/ai-catalog.json`, listing what the domain offers (MCP server, A2A agent, OKF bundle, site-specific APIs). v0.9 draft, so optional — but it's the discovery layer the MCP / A2A cards and OKF bundle pay off through. Two gotchas: the base spec ([`Agent-Card/ai-catalog`](https://github.com/Agent-Card/ai-catalog)) names the media-type field `mediaType` while the ARD layer ([`ards-project/ard-spec`](https://github.com/ards-project/ard-spec)) names it `type` — emit **both keys with the same value** so the entry validates under either reading (both specs require consumers to ignore unknown keys). ARD also adds an optional `representativeQueries` array of sample prompts per entry.
- **Nice** — OKF ([Open Knowledge Format](https://github.com/GoogleCloudPlatform/knowledge-catalog)) bundle: a tree of typed Skill source recorded

Only relevant when the site actually exposes an MCP server or A2A agent. Both are static JSON files declaring the endpoint, capabilities, and skills. Skip otherwise.<link rel="nlweb"> pointing to a conversational endpoint. NLWeb is early; the tag is one line and worth having, but it's not a scoring blocker in 2026./.well-known/ai-catalog.json, listing what the domain offers (MCP server, A2A agent, OKF bundle, site-specific APIs). v0.9 draft, so optional — but it's the discovery layer the MCP / A2A cards and OKF bundle pay off through. Two gotchas: the base spec (Agent-Card/ai-catalog) names the media-type field mediaType while the ARD layer (ards-project/ard-spec) names it type — emit both keys with the same value so the entry validates under either reading (both specs require consumers to ignore unknown keys). ARD also adds an optional representativeQueries array of sample prompts per entry.Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
