Site Health Audit Skill

Crawl any website via its sitemap and produce a comprehensive technical SEO audit with an Ahrefs-style health score.

When to Use

• User asks for a "site audit", "health check", or "technical SEO audit"
• User wants to find broken links on their website
• User asks about duplicate titles, missing meta descriptions, or other on-page SEO issues
• After a major site launch, redesign, or migration
• As a scheduled monthly audit to track site health over time

How to Run

The script auto-discovers the sitemap and requires zero npm dependencies.

Quick sample (50 pages)

Options

What It Checks (16 categories)

1. HTTP Status — 4xx/5xx errors
2. Title — missing, too short (<10), too long (>60)
3. Meta Description — missing, too short (<50), too long (>160)
4. H1 — missing or multiple H1 tags
5. Canonical — missing or non-self-referencing

15. Duplicate Descriptions — multiple pages with same meta description
16. Duplicate H1 — multiple pages sharing the same H1

Health Score Formula

Uses the Ahrefs formula:

score = (total_pages - pages_with_errors) / total_pages * 100

Only errors affect the score — warnings and notices are informational.

Where to Save Reports

Write audit reports to the Space filesystem so they persist and can be compared over time:

docs/seo/site-audit-YYYY-MM-DD.md

When running a follow-up audit, compare with the previous report to highlight improvements and regressions.
