# Site Health Audit

Inspects technical foundations: crawlability, indexation, performance, and architecture. Catches systemic issues before they affect rankings.

## Quick Start

```
Audit site health for [domain]
```

```
Check technical SEO on [URL]
```

```
Why are my pages not indexing?
```

## Engine Contract

- **Reads**: domain, sitemap URL, robot.txt, known issues
- **Writes**: technical audit report with severity-ranked fix list
- **Promotes**: critical technical blockers to hot cache
- **Next handoff**: signal packet with technical scores and recommended fixes

## Instructions

Run six checks:

1. **Indexability** — robots.txt rules, meta robots, noindex tags, canonical loops, redirect chains, 4xx/5xx errors
2. **Crawl Efficiency** — sitemap validity, orphan pages, crawl depth, internal link distribution, pagination
3. **Performance** — Core Web Vitals (LCP, INP, CLS), server response time, render-blocking resources, image optimization
4. **Security** — HTTPS enforcement, valid certificate, security headers, no mixed content
5. **Mobile** — mobile-friendly design, viewport config, tap target sizing, font readability
6. **Architecture** — flat vs deep structure, URL consistency, breadcrumb usage, hreflang if multilingual

## Severity Levels

- **Blocker**: Prevents indexing or causes major ranking loss (fix within 24 hours)
- **Warning**: Significant ranking friction (fix within 1 week)
- **Opportunity**: Improvement with measurable upside (fix within 1 month)
- **Observation**: Monitor but not urgent
