Solo SEO Audit

/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 analysis
• project_info(name) — get project URL if auditing by project name

If MCP tools are not available, use Claude WebSearch/WebFetch as fallback.

Steps

1. 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?"

2. 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

3. 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?

4. 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]

5. 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.

6. Score calculation (0-100):

   Check	Max Points	Criteria
   Title tag	10	Exists, 50-60 chars, contains primary keyword
   Meta description	10	Exists, 150-160 chars, compelling
   OG tags	10	og:title, og:description, og:image all present
   JSON-LD	10	Valid structured data present
   Canonical	5	Present and correct
   Sitemap	10	Exists, valid, referenced in robots.txt
   Robots.txt	5	Exists, no overly broad Disallow
   H1 structure	5	Exactly one H1, descriptive
   HTTPS	5	Site uses HTTPS
   Mobile meta	5	Viewport tag present
   Language	5	lang attribute on <html>
   Favicon	5	Exists
   SERP presence	15	Found in top 10 for target keywords

7. Write report to docs/seo-audit.md (in project context) or print to console:

   # SEO Audit: {URL}
   
   **Date:** {YYYY-MM-DD}
   **Score:** {N}/100
   
   ## Summary
   {2-3 sentence overview of SEO health}
   
   ## Checks
   
   | Check | Status | Score | Details |
   |-------|--------|-------|---------|
   | Title | pass/fail | X/10 | "{actual title}" (N chars) |
   | ... | ... | ... | ... |
   
   ## SERP Positions
   
   | Keyword | Position | Top Competitors |
   |---------|----------|----------------|
   | {kw} | #N or N/A | competitor1, competitor2, competitor3 |
   
   ## Critical Issues
   - {issue with fix recommendation}
   
   ## Recommendations (Top 3)
   1. {highest impact fix}
   2. {second priority}
   3. {third priority}
   

8. Output summary — print score and top 3 recommendations.

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.
