Full Website SEO Audit

Process

  1. Load reference — read
    seo/references/google-seo-guide.md
    for category-aligned checks
  2. Fetch homepage — use
    scripts/fetch_page.py
    to retrieve HTML
  3. Detect business type — analyze homepage signals per seo orchestrator
  4. Crawl site — follow internal links up to 500 pages, respect robots.txt
  5. 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
  6. Score — aggregate into SEO Health Score (0-100)
  7. Report — generate prioritized action plan

Live Data Insights (MCP Overlay)

This section appears only when MCP data sources are available. The static analysis above is complete and unchanged regardless of MCP availability.

MCP Availability Check

Follow the self-contained check pattern from

seo/references/mcp-degradation.md
:

  1. Use ToolSearch with query "+ahrefs" — if tools returned, Ahrefs is available
  2. Use ToolSearch with query "+google-search-console" — if tools returned, GSC is available
  3. Proceed with whichever MCPs are available; skip sections for unavailable MCPs

Domain Authority Context (Ahrefs)

If Ahrefs available: after completing the static scoring step, fetch domain-level metrics via

site-explorer-metrics
for the target domain (bare domain, no https://). Display a
### Domain Authority Context
section:

### Domain Authority Context

| Metric | Value |
|--------|-------|
| Domain Rating (DR) | XX/100 |
| Ahrefs Rank | #XX,XXX |
| Total Backlinks | XX,XXX |
| Referring Domains | X,XXX |
| Organic Keywords | XX,XXX |
| Est. Monthly Organic Traffic | XX,XXX visits |

Annotate the SEO Health Score line with: (Data enriched with live Ahrefs metrics)

Note: All monetary values (

traffic_cost
,
cpc
) from Ahrefs are in cents — divide by 100 before displaying as USD.

Indexing Status (GSC)

If GSC available: fetch indexing coverage using

get_indexing_status
for up to 20 top pages. Add a
### Indexing Status
section:

### Indexing Status (Google Search Console)

- Indexed pages: XX
- Not indexed: XX
  - Top reasons: [reason 1], [reason 2]
  - Non-indexed pages: [url1], [url2], ...

> Note: GSC property format — use sc-domain: for domain properties or full https:// URL for URL-prefix properties.

Top Performing Pages (GSC)

If GSC available: fetch

get_search_analytics
for the site's top pages (last 28 days, sorted by clicks). Add a
### Top Performing Pages
section:

### Top Performing Pages (Google Search Console — Last 28 Days)

| Page | Clicks | Impressions | CTR | Avg Position |
|------|--------|-------------|-----|--------------|
| /page-1 | X,XXX | XX,XXX | X.X% | X.X |
| /page-2 | ... | ... | ... | ... |

> CTR displayed as percentage (API returns decimal — multiply by 100 for display).
