# SEO Audit

Analyze application for search engine optimization and discoverability. Output to `.claude/audits/AUDIT_SEO.md`.

## Status Block (Required)

Every output MUST start with:
```yaml
---
agent: seo-auditor
status: COMPLETE | PARTIAL | SKIPPED | ERROR
timestamp: [ISO timestamp]
duration: [seconds]
findings: [count]
framework_detected: [next.js-app | next.js-pages | spa | static | unknown]
pages_scanned: [count]
errors: []
skipped_checks: []
---
```

## Framework Detection

First, detect the project structure:

```bash
# Next.js App Router
ls -d src/app 2>/dev/null && echo "FRAMEWORK: Next.js App Router"
ls -d app 2>/dev/null && echo "FRAMEWORK: Next.js App Router (root)"

# Next.js Pages Router
ls -d src/pages 2>/dev/null && echo "FRAMEWORK: Next.js Pages Router"
ls -d pages 2>/dev/null && echo "FRAMEWORK: Next.js Pages Router (root)"

# SPA / Static
ls index.html 2>/dev/null && echo "FRAMEWORK: Static/SPA"
ls public/index.html 2>/dev/null && echo "FRAMEWORK: CRA/SPA"

# Check for meta framework
grep -l "astro" package.json 2>/dev/null && echo "FRAMEWORK: Astro"
grep -l "gatsby" package.json 2>/dev/null && echo "FRAMEWORK: Gatsby"
grep -l "nuxt" package.json 2>/dev/null && echo "FRAMEWORK: Nuxt"
```

**Adjust patterns based on detection:**
- **Next.js App Router:** Look for `metadata` exports in `page.tsx`
- **Next.js Pages Router:** Look for `Head` component in pages
- **SPA/Static:** Look for `<meta>` tags in `index.html`
- **Unknown:** Use generic patterns, note "Framework not detected"

## Check

**Meta Tags**
- Title tag present and unique per page
- Meta description present (150-160 chars)
- Viewport meta tag set
- Canonical URL defined
- Robots meta (index, follow)

**OpenGraph & Social**
- og:title, og:description, og:image
- Twitter card tags
- Image dimensions correct (1200x630 for OG)
- Social preview works

**Technical SEO**
- Sitemap.xml exists and valid
- Robots.txt configured
- Clean URL structure
- No duplicate content
- Mobile friendly

**Structured Data**
- JSON-LD schema present
- Schema type appropriate (Article, Product, etc.)
- Required fields populated
- Valid when tested

**Performance & UX (SEO Impact)**
- Page speed acceptable
- No layout shift (CLS)
- Core Web Vitals passing
- Accessible (alt tags, headings)

**Content**
- H1 tag present (one per page)
- Heading hierarchy correct
- Alt text on images
- Internal linking

```

## Critical Issues

### SEO-001: Missing Meta Descriptions
**Pages affected:** 15/20
**Issue:** No meta description means Google creates one from page content
**Impact:** Lower CTR in search results
**Files:**
- `src/app/page.tsx`
- `src/app/about/page.tsx`
- `src/app/products/page.tsx`
**Fix (Next.js App Router):**
```typescript
export const metadata: Metadata = {
  title: 'Page Title | Brand',
  description: 'Compelling 150-160 character description...',
};
```
**Fix (Next.js Pages Router):**
```typescript
import Head from 'next/head';
<Head>
  <title>Page Title | Brand</title>
  <meta name="description" content="Compelling description..." />
</Head>
```
**Fix (SPA/Static):**
```html
<head>
  <title>Page Title | Brand</title>
  <meta name="description" content="Compellin
