What Full Website SEO Audit does

The Full Website SEO Audit skill provides a robust solution for analyzing the SEO health of websites. By leveraging automated crawling capabilities, it can assess up to 500 pages, ensuring a thorough evaluation of a site's structure and content. The process begins with rendering the homepage to capture essential data such as raw HTML and accessibility metrics. Following this, the skill intelligently detects the business type based on the homepage signals, allowing for tailored recommendations throughout the audit process.

Once the business type is established, the skill crawls the website, adhering to the robots.txt directives and following internal links. It utilizes a delegation system to engage up to 15 specialized subagents, each focusing on different aspects of SEO, including technical SEO, content quality, schema validation, performance metrics, and more. This parallel processing not only speeds up the audit but also ensures that each component is examined by an expert subagent, resulting in a comprehensive health score and actionable insights.

The output of the audit is structured and detailed, with various reports generated to highlight findings and recommendations. Users receive a prioritized action plan, which categorizes issues by severity, alongside a full audit report that includes screenshots and detailed analyses of each SEO category. This skill is particularly beneficial for web developers, digital marketers, and SEO specialists looking to enhance their website's performance and visibility in search engines.

When to use it

Use this skill when you need a detailed SEO audit of a website to enhance its search engine visibility and overall health.

When not to use it

This skill may not be suitable for very small websites or those with fewer than 10 pages, as the crawling capabilities are optimized for larger sites.

Full Website SEO Audit

Process

  1. Render homepage: use claude-seo run render_page.py <url> --mode auto --json to capture raw HTML, rendered HTML, extracted text, SPA status, and accessibility data when needed
  2. Detect business type: analyze homepage signals per seo orchestrator
  3. Crawl site: follow internal links up to 500 pages, respect robots.txt
  4. Delegate to subagents (if available, otherwise run inline sequentially):
    • seo-technical -- robots.txt, sitemaps, canonicals, Core Web Vitals, security headers
    • seo-content -- E-E-A-T, readability, thin content, AI citation readiness
    • seo-schema -- detection, validation, generation recommendations
    • seo-sitemap -- structure analysis, quality gates, missing pages
    • seo-performance -- LCP, INP, CLS measurements
    • seo-visual -- screenshots, mobile testing, above-fold analysis
    • seo-geo -- AI crawler access, llms.txt, citability, brand mention signals
    • seo-local -- GBP signals, NAP consistency, reviews, local schema, industry-specific local factors (spawn when Local Service industry detected: brick-and-mortar, SAB, or hybrid business type)
    • seo-maps -- Geo-grid rank tracking, GBP audit, review intelligence, competitor radius mapping (spawn when Local Service detected AND DataForSEO MCP available)
    • seo-google -- CWV field data (CrUX), URL indexation (GSC), organic traffic (GA4) (spawn when Google API credentials detected via claude-seo run google_auth.py --check)
    • seo-backlinks -- Backlink profile data: DA/PA, referring domains, anchor text, toxic links (spawn when Moz or Bing API credentials detected via claude-seo run backlinks_auth.py --check, or always include Common Crawl domain-level metrics)
    • seo-cluster -- Semantic clustering analysis (spawn when content strategy signals detected: blog, pillar pages, topic clusters)
    • seo-sxo -- Search experience analysis: page-type mismatch, user stories, persona scoring (always include in full audits)
    • seo-drift -- Drift analysis: compare against stored baseline (spawn when drift baseline exists for the URL via claude-seo run drift_history.py <url>)
    • seo-ecommerce -- Product schema, marketplace intelligence (spawn when E-commerce industry detected)
  5. Score -- aggregate into SEO Health Score (0-100)
  6. Persist audit artifacts -- write all outputs under {domain}-audit/
  7. Report -- generate prioritized action plan and optional PDF/HTML report

Crawl Configuration

Max pages: 500
Respect robots.txt: Yes
Follow redirects: Yes (max 3 hops)
Timeout per page: 30 seconds
Concurrent requests: 5
Delay between requests: 1 second

Output Files

  • {domain}-audit/FULL-AUDIT-REPORT.md: Comprehensive findings
  • {domain}-audit/ACTION-PLAN.md: Prioritized recommendations (Critical > High > Medium > Low)
  • {domain}-audit/audit-data.json: Structured audit envelope for report generation
  • {domain}-audit/findings/*.md: Per-category specialist findings (technical.md, content.md, schema.md, performance.md, visual.md, etc.)
  • {domain}-audit/screenshots/: Desktop + mobile captures (if Playwright available)
  • PDF Report (recommended): Generate a professional A4 PDF using claude-seo run google_report.py --type full --data {domain}-audit/audit-data.json --domain <domain> --output-dir {domain}-audit/. This produces a white-cover enterprise report with TOC, executive summary, charts (Lighthouse gauges, query bars, index donut), metric cards, threshold tables, prioritized recommendations with effort estimates, and implementation roadmap. Always offer PDF generation after completing an audit.

Structured Audit Data Envelope

Write {domain}-audit/audit-data.json with this shape so claude-seo run google_report.py --type full --data {domain}-audit/audit-data.json --domain <domain> --output-dir {domain}-audit/ can generate a report even when Google API data is unavailable:

DataForSEO Integration (Optional)

If DataForSEO MCP tools are available, spawn the seo-dataforseo agent alongside existing subagents to enrich the audit with live data: real SERP positions, backlink profiles with spam scores, on-page analysis (Lighthouse), business listings, and AI visibility checks (ChatGPT scraper, LLM mentions).

Google API Integration (Optional)

If Google API credentials are configured (claude-seo run google_auth.py --check), spawn the seo-google agent to enrich the audit with real Google field data: CrUX Core Web Vitals (replaces lab-only estimates), GSC URL indexation status, search performance (clicks, impressions, CTR), and GA4 organic traffic trends. The Performance (CWV) category score benefits most from field data.

Error Handling

ScenarioAction
URL unreachable (DNS failure, connection refused)Report the error clearly. Do not guess site content. Suggest the user verify the URL and try again.
robots.txt blocks crawlingReport which paths are blocked. Analyze only accessible pages and note the limitation in the report.
Rate limiting (429 responses)Back off and reduce concurrent requests. Report partial results with a note on which sections could not be completed.
Timeout on large sites (500+ pages)Cap the crawl at the timeout limit. Report findings for pages crawled and estimate total site scope.
