What it produces
  • Technical SEO audit report across 9 categories
  • Agent-UX score (0-100) plus itemized issues
  • Accessibility tree findings
What it needs
  • URL to audit

Limits and human review

The skill provides technical audit checks and guidance but cannot guarantee ranking success, nor can it verify the real-time effectiveness of implemented fixes. It also relies on specific commands like `claude-seo run agent_ux_check.py` to perform detailed audits [2].

# Agent-friendly pages — audit reference (June 2026)

The next wave of AI search is not summarization — it's **agents** acting on the
user's behalf (search, compare, buy, book). Google's AI optimization guide and
the linked web.dev article describe three channels through which agents
interpret your site:

1. **Screenshots + vision model** — interprets visual hierarchy, button
   prominence, layout. Slow and token-expensive.
2. **Raw HTML / DOM** — nesting, IDs, classes, data attributes.
3. **The accessibility tree** — the browser-native semantic distillation
   (roles, names, states). The cleanest signal of the three.

Modern agents combine all three. Optimizing for the **accessibility tree** is
the single highest-leverage move; if your accessibility tree is broken, no
amount of visual polish saves you.

  https://developers.google.com/search/docs/fundamentals/ai-optimization-guide
- web.dev (referenced from the guide above): article on building
  agent-friendly websites

# Technical SEO Audit

## Categories

### 1. Crawlability
- robots.txt: exists, valid, not blocking important resources
- XML sitemap: run `claude-seo run sitemap_discovery.py <url> --json`; require a
  valid entry in `found`, and report stale or unsafe robots.txt declarations
  separately from working fallback locations
- Noindex tags: intentional vs accidental
- Crawl depth: important pages within 3 clicks of homepage
- JavaScript rendering: check if critical content requires JS execution
- Crawl budget: for large sites (>10k pages), efficiency matters
- Googlebot **fetch limits**: Googlebot fetches the first **2MB of HTML** and first **64MB of a PDF** (uncompressed; 15MB is the broader crawler-infra default)

A skill is instructions your agent will follow and scripts it may run, so who checked it matters as much as how many people installed it.
