SEO health check for any URL — analyzes meta tags, OG, JSON-LD, sitemap, robots.txt, SERP positions, and scores 0-100. Use when user says "check SEO", "audit this page", "SEO score", "check meta tags", or "SERP position". Do NOT use for generating landing content (use /landing-gen) or social media posts (use /content-gen).

/seo-audit
SEO health check for any URL or project landing page. Fetches the page, analyzes meta tags, OG, JSON-LD, sitemap, robots.txt, checks SERP positions for target keywords, and outputs a scored report.
MCP Tools (use if available)
web_search(query, engines, include_raw_content)— SERP position check, competitor analysisproject_info(name)— get project URL if auditing by project name
If MCP tools are not available, use Claude WebSearch/WebFetch as fallback.
Steps
Parse target from
$ARGUMENTS.- If URL (starts with
http): use directly. - If project name: look up URL from project README, CLAUDE.md, or
docs/prd.md. - If empty: ask via AskUserQuestion — "Which URL or project to audit?"
- If URL (starts with
Fetch the page via WebFetch. Extract:
<title>tag (length check: 50-60 chars ideal)<meta name="description">(length check: 150-160 chars ideal)- Open Graph tags:
og:title,og:description,og:image,og:url,og:type - Twitter Card tags:
twitter:card,twitter:title,twitter:image - JSON-LD structured data (
<script type="application/ld+json">) <link rel="canonical">— canonical URL<html lang="...">— language tag<link rel="alternate" hreflang="...">— i18n tags- Heading structure: H1 count (should be exactly 1), H2-H3 hierarchy
Check infrastructure files:
- Fetch
{origin}/sitemap.xml— exists? Valid XML? Page count? - Fetch
{origin}/robots.txt— exists? Disallow rules? Sitemap reference? - Fetch
{origin}/favicon.ico— exists?
- Fetch
Forced reasoning — assess before scoring:
Write out before proceeding:- What's present: [list of found elements]
- What's missing: [list of absent elements]
- Critical issues: [anything that blocks indexing or sharing]
SERP position check — for 3-5 keywords:
- Extract keywords from page title + meta description + H1.
- For each keyword, search via MCP
web_search(query="{keyword}")or WebSearch. - Record: position of target URL in results (1-10, or "not found").
- Record: top 3 competitors for each keyword.

Notes
- Score is relative — 80+ is good for a landing page, 90+ is excellent
- SERP checks are approximations (not real-time ranking data)
- Run periodically after content changes or before launch
Common Issues
Page fetch fails
Cause: URL is behind authentication, CORS, or returns non-HTML.
Fix: Ensure the URL is publicly accessible. For SPAs, check if content is server-rendered.
SERP positions show "not found"
Cause: Site is new or not indexed by search engines.
Fix: This is expected for new sites. Submit sitemap to Google Search Console and re-audit in 2-4 weeks.
Low score despite good content
Cause: Missing infrastructure files (sitemap.xml, robots.txt, JSON-LD).
Fix: These are the highest-impact fixes. Generate sitemap, add robots.txt with sitemap reference, and add JSON-LD structured data.
