Automated summary

Runs a full website SEO audit by crawling up to 500 pages, delegating analysis to specialised subagents, and producing a health score with a prioritised action plan.

Strengths

  • Parallel orchestration of up to 15 specialist subagents (technical, content, schema, sitemap, performance, GEO, SXO, drift)
  • Automatic business-type detection that conditionally spawns relevant agents (local, e-commerce, backlinks, Google APIs)
  • Concrete deliverables: FULL-AUDIT-REPORT.md, ACTION-PLAN.md, Playwright screenshots and an optional professional A4 PDF report
  • Disciplined crawling: honours robots.txt, caps at 500 pages, limits redirects to 3 hops and throttles requests

Limitations

  • Advanced modules (DataForSEO, Moz/Bing, CrUX/GSC/GA4) only run when external credentials are configured
  • Parallel delegation depends on subagent availability; otherwise execution falls back to slow sequential runs
  • Core Web Vitals metrics and screenshots rely on Playwright and third-party tooling
When to use it

Use it when you need a whole-site, scored SEO diagnosis with recommendations ranked by priority.

When not to use it

Avoid it for checking a single page, a one-off tag issue or a targeted content rewrite, where a full crawl is overkill.

Security analysis

Caution
Quality score82/100

The instructions themselves are benign: no destructive commands, no obfuscation, no secrets transmitted externally, and it explicitly respects robots.txt and handles errors gracefully. The caution rating stems from the reliance on unlisted local scripts and broad outbound crawling plus credential-detection steps — all consistent with a real SEO audit tool, but beyond pure-static, zero-execution risk.

Findings
  • •Executes bundled Python scripts (fetch_page.py, google_auth.py, backlinks_auth.py, drift_history.py, google_report.py) whose contents are not included in the SKILL.md, so actual behavior cannot be verified from the listing alone
  • •Performs network activity: crawls up to 500 pages of an arbitrary user-supplied URL and follows redirects/links
  • •Probes for stored third-party API credentials (Google/GSC/GA4, Moz, Bing, DataForSEO) via auth-check scripts, which is legitimate but touches sensitive credential state
  • •Spawns up to 15 subagents that inherit network access, expanding the attack/behavior surface

Full Website SEO Audit

Process

  1. Fetch homepage: use scripts/fetch_page.py to retrieve HTML
  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 python scripts/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 python scripts/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 python scripts/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. Report -- generate prioritized action plan

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

  • FULL-AUDIT-REPORT.md: Comprehensive findings
  • ACTION-PLAN.md: Prioritized recommendations (Critical > High > Medium > Low)
  • screenshots/: Desktop + mobile captures (if Playwright available)
  • PDF Report (recommended): Generate a professional A4 PDF using scripts/google_report.py --type full. 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.

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 (python scripts/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

| Scenario | Action | |----------|--------| | 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 crawling | Report 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. |

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/seo-audit-mrwakdl1/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/seo-audit-mrwakdl1' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/seo-audit-mrwakdl1/download' --output '.skill-downloads/seo-audit-mrwakdl1/SKILL.md.part' && mv '.skill-downloads/seo-audit-mrwakdl1/SKILL.md.part' '.skill-downloads/seo-audit-mrwakdl1/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/seo-audit-mrwakdl1/SKILL.md' && test -s '.skill-downloads/seo-audit-mrwakdl1/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/seo-audit' && cp -R '.skill-downloads/seo-audit-mrwakdl1' '.claude/skills/seo-audit'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/seo-audit-mrwakdl1'

openskills read 'seo-audit-mrwakdl1'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/seo-audit-mrwakdl1/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
