--- name: seo-audit-full description: >- Advanced full SEO audit skill. Runs its own full workflow from local scripts, including the basic SEO checks plus PageSpeed, social metadata, and advanced review modules when available. metadata: author: Jeff version: "2.1" --- # seo-audit-full — Advanced Full SEO Audit This skill runs a full single-page SEO audit from the `seo-audit-full` directory. It does not route to `seo-audit` when only a URL is provided. --- ## When to Use This Skill Use `seo-audit-full` when the user asks for: - "seo-audit-full" - "full SEO audit" - "advanced SEO audit" - "technical SEO audit" - "deep audit" - "comprehensive SEO review" - "audit everything" URL-only requests are valid. When external datasets are not supplied, run the full public-signal workflow and clearly note missing data sources in the report. --- ## Input Expected | Input | Required | Notes | |-------|----------|-------| | Page URL | Yes | The primary page to audit | | Primary keyword | Recommended | Improves content relevance scoring | | PageSpeed API key | Yes | Required for full audit PageSpeed checks. Ask at the start and do not run PageSpeed without it. | | Raw HTML or page content | Optional | Enables more accurate content checks when supplied | | GSC / crawl / analytics data | Optional | Include when supplied, otherwise mark unavailable | | Competitor benchmark data | Optional | Include when supplied | At the start of a full audit, ask the user for a PageSpeed Insights API key: ``` For PageSpeed checks, please provide a Google PageSpeed Insights API key. Get one here: https://developers.google.com/speed/docs/insights/v5/get-started Open "Acquiring and using an API key" → "Get a Key". If you do not provide one, I will stop before running the full audit because PageSpeed is a required full-audit module. ``` Do not run `seo-audit-full` PageSpeed checks without a PageSpeed API key supplied by `--api-key`, `PAGESPEED_API_KEY`, or `GOOGLE_PAGESPEED_API_KEY`. If the key is missing, stop and ask the user to configure it instead of rendering a full report with missing PageSpeed data. --- ## Architecture: Full = Core + Performance + Advanced ``` ┌─────────────────────────────────────────────────────────────┐ │ seo-audit-full Workflow │ │ │ │ Phase 1: Run core scripts (./scripts/) │ │ ┌──────────────────────────────────────────────────────┐ │ │ │ check-site.py → robots.txt, sitemap, 404, URL │ │ │ │ check-page.py → title, H1, meta desc, slug │ │ │ │ check-schema.py → JSON-LD validation │ │ │ │ fetch-page.py → raw HTML for analysis │ │ │ └──────────────────────────────────────────────────────┘ │ │ ↓ │ │ Phase 2: Run performance + full-only scripts (./scripts/) │ │ ┌──────────────────────────────────────────────────────┐ │ │ │ check-pagespeed.py → Lighthouse scores + metrics │ │ │ │ check-social.py → OG Tags + Twitter Card │ │ │ │ (more scripts added here as modules grow) │ │ │ └──────────────────────────────────────────────────────┘ │ │ ↓ │ │ Phase 3: LLM-only advanced checks │ │ ┌──────────────────────────────────────────────────────┐ │ │ │ E-E-A-T content quality scoring │ │ │ │ Duplicate content signals │ │ │ │ Anchor text quality assessment │ │ │ └──────────────────────────────────────────────────────┘ │ └─────────────────────────────────────────────────────────────┘ ``` --- ## Output Produce an **Advanced Full SEO Audit Report** by filling the template at [assets/report-template.html](assets/report-template.html), then **save it to a file — never print raw HTML to the terminal**. **File naming:** `reports/--full-audit.html` ``` https://example.com/blog/best-tools → reports/example-com-blog-best-tools-full-audit.html https://example.com/ → reports/example-com-full-audit.html ``` **After saving, tell the user:** ``` ✅ Full Report saved → reports/example-com-full-audit.html Open it now? (yes / no) ``` If yes → run: `open reports/example-com-full-audit.html` **Template placeholders** — fill each independently: | Placeholder | Content | |---|---| | `{{summary_verdict}}` | One sentence: total checks run, how many failed/warned/passed | | `{{summary_critical_html}}` | `
  • ` per critical item, or `
  • None
    • ` | | `{{summary_warnings_html}}` | `
  • ` per warning item, or `
  • None
    • ` | | `{{summary_passing_html}}` | `
  • ` per passing check, or `

All output is structured JSON — use it directly as evidence. **Dependencies:** `pip install requests` ### Phase 1: Core scripts ```bash # 1. site-level checks (robots.txt + sitemap.xml + 404 + URL canonicalization) python scripts/check-site.py https://example.com # 2. page-level checks (H1, title, meta description, canonical, URL slug) python scripts/check-page.py https://example.com --keyword "primary keyword" # 3. fetch raw HTML for downstream scripts python scripts/fetch-page.py https://example.com --output /tmp/page.html # 4. JSON-LD schema validation python scripts/check-schema.py --file /tmp/page.html ``` ### Phase 2: Full-only scripts ```bash # 5. PageSpeed / Lighthouse checks python scripts/check-pagespeed.py https://example.com --strategy mobile --timeout 180 --api-key "USER_PROVIDED_KEY" # If no key was provided, do not run this command. Ask the user to configure a PageSpeed API key first. # 6. Social tags: OG + Twitter Card validation python scripts/check-social.py --file /tmp/page.html # Or directly from URL: python scripts/check-social.py https://example.com ``` Each script exits with code `0` (all pass/warn) or `1` (any fail/error). PageSpeed can take 200 seconds. Use a 180-second timeout by default. If it still times out, mark the Page Speed module as `error` and state that the PageSpeed API timed out; do not treat that as confirmed page performance failure. If PageSpeed fails because Google returns a quota/API-key error after a key was provided, keep the audit running and render the PageSpeed module as `error` with this instruction: `Get a PageSpeed API key at https://developers.google.com/speed/docs/insights/v5/get-started → "Acquiring and using an API key" → "Get a Key".` --- ## Scope — Full Audit Check Whitelist Full runs its own core checks plus the full-only items marked ★ below. ### Site-Level Checks (in `{{site_checks_html}}`) Core checks: - Sitemap URL Inventory · Staging Subdomain Indexation · robots.txt · sitemap.xml · 404 Handling · URL Canonicalization · i18n / hreflang **Staging Subdomain Indexation rules:** - Check common staging/test hosts before robots.txt: `test.`, `staging.`, `dev.`, `preview.`, `beta.`, `uat.` - **Fail** when a staging/test subdomain is publicly accessible, closely mirrors the production site, and is not protected by authentication, `noindex`, or a blocking `robots.txt`. - **Warn** when a staging/test subdomain is publicly accessible but similarity or index protection cannot be confirmed. - **Pass** when no public staging/test subdomain is detected, or detected staging hosts are protected by authentication, non-200 access, `noindex`, or `Disallow: /`. - Explain the impact as duplicate indexable pages: Google may treat `test.example.com` and `www.example.com` as separate but near-identical URLs, splitting ranking signals and competing with the production site. - Recommended fixes: add Basic Auth/password protection first; also block crawlers on the staging host with `User-agent: *` + `Disallow: /`; add page-level `noindex` if pages can still be accessed. **Sitemap URL Inventory rules:** - Place this as the first module in `{{site_checks_html}}`, before the Crawlability table. - Render it as its own table with columns: Directory · URL Count · Page Type · Example Page. - Use `check-site.py` `sitemap_inventory` output to summarize first-level directories, URL counts, inferred page types, and one representative example URL. - Treat this as a site-level map, not a pass/fail single-page SEO audit. - Use status `info` unless sitemap URLs cannot be parsed; do not penalize a site for having many or few URLs in a directory without deeper evidence. - Always include a next-step note: the user can continue with deeper full audits by selecting representative sample URLs from major directories such as `/blog/`, `/tools/`, `/alternatives/`, `/templates/`, or `/use-cases/`. ### Page Speed Checks (in `{{pagespeed_checks_html}}`) Full-only: - Lighthouse category scores: Performance · Accessibility · Best Practices · SEO - Lab metrics: FCP · LCP · TBT · CLS · Speed Index - Final URL and screenshot availability ### E-E-A-T Checks (in `{{eeat_checks_html}}`) Core checks: - About Us · Contact · Privacy Policy · Terms of Service · Media/Partners (only if present) Contact logic (Contact row only): - A dedicated `/contact` page is **not required** - **Pass** if contact is reachable via any of: dedicated contact page (HTTP 200) · About page with contact details · footer/nav mailto, email, social links, or contact form - **Fail** only when no contact pathway exists anywhere on the site - Missing `/contact` alone is **not** a fail when About or footer/nav already expose contact info E-E-A-T infrastructure rules — two layers per trust page: - **Layer 1 — Exists:** HTTP 200 for the trust page URL (Contact uses Contact-specific rules above) - **Layer 2 — Reachable:** linked from footer or main nav | Page | Required | |---|---| | About Us | Yes | | Contact | Yes — dedicated page optional; About or footer/nav contact details satisfy this | | Privacy Policy | Yes | | Terms of Service | Yes | | Media / Partners | No — include only if present | Status rules (About, Privacy, Terms, Media/Partners): - Page missing (non-200) → **Fail** - Page exists but not linked in footer/nav → **Warn** - Page exists and linked in footer/nav → **Pass** - Optional page missing → skip, do not include row **Contact-specific rules:** 1. Try common paths (`/contact`, `/contact-us`) — HTTP 200 counts as Exists 2. If no contact page, check the About page body for email, social, or contact details 3. Also scan homepage footer and nav for `mailto:`, visible email, social links, or a contact form 4. **Exists Pass** if any contact pathway is found 5. **Exists Fail** only when no contact information is found anywhere 6. **Reachable Pass** if a contact page link or contact details appear in footer/nav 7. **Reachable Warn** if contact is only reachable inside About page content, not directly in footer/nav 8. Do not recommend creating `/contact` when About or footer already expose contact info ### Page-Level Checks (in `{{page_checks_html}}`), output in this exact order: Core checks: URL Slug · Title Tag · Meta Description · H1 Tag · Canonical Tag · Image Alt Text · Word Count · Keyword Placement · Heading Structure · Internal Links · Schema (JSON-LD) **Schema (JSON-LD) rules:** - Treat Schema as a quality check, not only a presence check. - Validate JSON-LD parseability, expected `@type`, required fields, recommended rich-result fields, nested fields, and primary-type conflicts. - **Fail** when JSON-LD is invalid, the expected schema type is missing, required fields are missing, or localized schema clearly points to the wrong language/URL. - **Warn** when recommended fields are missing, nested fields are incomplete, multilingual pages lack `inLanguage`, or localized schema cannot be fully confirmed. - **Pass** only when the expected schema type is present, required fields are present, no conflicts are found, and localized schema matches the current page language/URL when applicable. - For multilingual pages, each language version should have its own schema with matching `inLanguage`, language-specific headline/description where present, and `url` / `mainEntityOfPage` pointing to the current localized canonical URL. ★ Full-only additions: - **OG Tags** — og:title, og:description, og:image, og:type, og:url presence and validity - **Twitter Card** — twitter:card type, title/description/image (with OG fallback detection) --- ## How to Use Script JSON Output Same rules across full audit modules — map each field's `status` directly to the report check table: - `status` → `pass` / `warn` / `fail` / `error` → badge in report - `detail` → starting point for Evidence line - Do not contradict script output unless you have additional observable evidence **For `check-site.py` output:** - `staging_subdomains.status` → Staging Subdomain Indexation row status - `staging_subdomains.detail` → Staging Subdomain Indexation row detail - `staging_subdomains.public_hosts` → evidence for public staging/test hosts - `staging_subdomains.similar_hosts` → fail evidence for production-like staging duplicates - `robots.status` → robots.txt row status - `sitemap.status` → sitemap.xml row status - `sitemap_inventory.status` → Sitemap URL Inventory module status - `sitemap_inventory.directories[]` → table rows with `path`, `url_count`, `page_type`, and `example_url` - `sitemap_inventory.detail` → short explanatory note below the inventory table **For `check-schema.py` output:** - `status` → Schema (JSON-LD) row status - `detail` → Schema (JSON-LD) row detail - `parse_errors` → fail evidence for malformed JSON-LD - `schemas[].fields_missing` → fail evidence for missing required schema fields - `schemas[].recommended_missing` and `schemas[].nested_issues` → warning evidence - `localized_schema.status` → language/URL alignment status for multilingual schema - `localized_schema.issues` → evidence for schema language or URL mismatch **For `check-social.py` output:** - `og.status` → OG Tags row status - `twitter_card.status` → Twitter Card row status - `og.fields.*` → individual field details for the detail cell - `twitter_card.fields.*` → individual field details, note fallback fields **For `check-pagespeed.py` output:** - `status` → overall Page Speed status - `category_status` → Lighthouse Scores badge status - `metric_status` → Core Lab Metrics badge status - `final_url` → Final URL line - `categories.performance.score` → Performance score - `categories.accessibility.score` → Accessibility score - `categories["best-practices"].score` → Best Practices score - `categories.seo.score` → SEO score - `compact_metrics.fcp.display_value` → FCP - `compact_metrics.lcp.display_value` → LCP - `compact_metrics.tbt.display_value` → TBT - `compact_metrics.cls.display_value` → CLS - `compact_metrics.si.display_value` → Speed Index - `screenshot` truthy → Screenshot available Do not use overall `status` for the Lighthouse Scores badge. Category scores use Lighthouse thresholds: 90–100 pass, 50–89 warn, 0–49 fail. Example: Performance 60, Accessibility 84, Best Practices 100, SEO 100 means `category_status` is `warn`. If LCP or Speed Index fails, `metric_status` and overall `status` may be `fail` while the Lighthouse Scores panel remains `warn`. Inside `{{pagespeed_checks_html}}`, include a short `Priority Actions` list after the score/metric cards. Keep it to 2–4 concise items based on failing or warning PageSpeed fields: - LCP slow → optimize hero media, preload critical image, reduce render-blocking CSS - Speed Index slow → defer non-critical scripts and reduce above-the-fold JS/CSS - TBT high → split long tasks and delay third-party tags - Performance score warning/fail → prioritize the biggest Lighthouse opportunities Always include the official diagnostic link: `https://pagespeed.web.dev/` --- ## LLM Review Instructions ### Core LLM reviews Resolve every `llm_review_required: true` field before writing the report: H1 semantic judgment, Title keyword position, URL Slug evaluation, and Meta Description quality must all receive an explicit judgment. ### Full-only LLM checks **OG Tags quality (always review):** ``` og:title : Does it differ meaningfully from ? It should be optimized for social sharing. og:description : Is it compelling for social feeds? Different focus than meta description is OK. og:image : Is the URL an actual image path (not a page URL)? ``` **Twitter Card completeness:** ``` If twitter:card is "summary_large_image", twitter:image (or og:image fallback) must be at least 300x157px. Flag if the image URL looks like a small icon or favicon. ``` --- ## Recommended Workflow 1. **Acknowledge full scope** — confirm this is a full audit 2. **Infer primary keyword** — read the page H1, title, and first paragraph unless the user provided one 3. **Phase 1: Run core scripts** — check-site → check-page → fetch-page → check-schema 4. **Phase 2: Run full-only scripts** — verify PageSpeed API key exists, then run check-pagespeed → check-social 5. **Core checks** — 404 handling, URL canonicalization, E-E-A-T trust pages, i18n/hreflang 6. **PageSpeed checks** — summarize Lighthouse category scores and lab metrics 7. **LLM-only advanced checks** — E-E-A-T content quality, duplicate content signals, anchor text quality 8. **Summarize findings** — Evidence / Impact / Fix format 9. **Priority actions** — top 5 highest-impact fixes with effort/impact tags 10. **Render report** — save to `reports/<hostname>-<slug>-full-audit.html` --- ## Report Detail Writing Rules Use strict formatting: **Pass → one short phrase. No lists, no elaboration.** **Warn → one `<div class="detail-issue">` with ≤2 bullet points. One `<div class="detail-fix">`.** **Fail → same as Warn. Lead with the exact failure.** --- ## Mandatory Finding Format ``` **Finding: [Finding Title]** - **Evidence:** [Observable fact, data point, or marked assumption] - **Impact:** [SEO / UX consequence] - **Fix:** [Actionable recommendation with example] ``` For Priority Actions, add effort/impact tags: ``` 1. [High Impact / Low Effort] Fix og:image — social shares currently show no preview. ``` --- ## Reference Files - Detailed audit modules and field definitions: [references/REFERENCE.md](references/REFERENCE.md) - Final HTML report template: [assets/report-template.html](assets/report-template.html) - PageSpeed validation script: [scripts/check-pagespeed.py](scripts/check-pagespeed.py) - Social tags validation script: [scripts/check-social.py](scripts/check-social.py) - Core scripts: [scripts/](scripts/) (check-site, check-page, check-schema, fetch-page)
