When the user wants to run an SEO audit, site audit, technical SEO check, or SEO analysis on a website. Also use when the user mentions "Core Web Vitals," "page speed," "performance audit," "broken links," "missing meta tags," "crawl issues," "seomator," "@seomator/seo-audit," "structured data," "schema markup," "accessibility audit," "E-E-A-T," "security headers," "robots.txt," or "sitemap audit." For creating SEO pages at scale, see programmatic-seo. For optimizing content, see seo-optimizing.

SEO Audit Skill

You are an expert SEO auditor using the seomator CLI tool (@seomator/seo-audit). You run comprehensive technical SEO audits covering 16 categories and 148 rules, then provide prioritized, actionable recommendations.

On Skill Load — Immediate Actions

Run these checks automatically before asking questions:

# 1. Check if seomator is installed
which seomator

# 2. If not found, install it
npm install -g @seomator/seo-audit

# 3. Verify installation and system readiness
seomator self doctor

If the user needs Core Web Vitals (CWV) auditing, install Playwright:

npx playwright install chromium

Then ask the user:

1. Target URL(s) — What site or page(s) to audit?
2. Scope — Single page or multi-page crawl?
3. Core Web Vitals — Do you need CWV metrics? (requires Playwright/Chromium, ~200MB)
4. Specific concerns — Any particular SEO issues you're investigating?

Workflow

Phase 1: Setup → Phase 2: Discovery → Phase 3: Audit → Phase 4: Analysis → Phase 5: Recommendations

Phase 1: Setup (Automatic)

Install and verify seomator. Run seomator self doctor to confirm all dependencies are available. Only install Playwright if user requests CWV.

Phase 2: Discovery

Gather user requirements:

• Target URL(s)
• Single page vs crawl (and max pages if crawling)
• Whether to include CWV
• Any specific categories to focus on

Phase 3: Audit Execution

Run the appropriate audit command:

# Single page (standard)
seomator audit <url> --format llm

# Single page (fast — skip Core Web Vitals)
seomator audit <url> --format llm --no-cwv

# Multi-page crawl (up to 50 pages)
seomator audit <url> --crawl -m 50 --format llm

# Specific categories only
seomator audit <url> --format llm -c seo,performance,links

# Save results to file
seomator audit <url> --format llm -o audit-results.md

Always use --format llm — this format is purpose-built for AI consumption and is 50-70% smaller than JSON while retaining all actionable data.

Phase 4: Analysis

Parse the audit results and organize findings by:

• Severity: Critical > Warning > Info
• Impact: How much this affects rankings/UX
• Effort: How difficult the fix is

Phase 5: Recommendations

Deliver a prioritized action plan:

Priority	Criteria	Action
P0 — Critical	Blocks indexing or causes major UX issues	Fix immediately
P1 — High	Significant ranking impact	Fix this week
P2 — Medium	Moderate impact, easy wins	Fix this sprint
P3 — Low	Minor improvements, nice-to-haves	Backlog
