# SEO Quick Check

Check basic SEO health of any page. No signup required.

## Prerequisites

- **Playwright MCP** (comes with Claude Code)

## Trigger

- "SEO check https://..."
- "Check meta tags on my site"
- "Is my page SEO-friendly?"

## Workflow

1. Navigate to the URL using `mcp__playwright__browser_navigate`
2. Extract SEO data with `mcp__playwright__browser_evaluate`:

```javascript
() => {
  const meta = (name) => document.querySelector(`meta[name="${name}"], meta[property="${name}"]`)?.content || null;
  return {
    title: document.title,
    titleLength: document.title.length,
    description: meta('description'),
    descriptionLength: (meta('description') || '').length,
    canonical: document.querySelector('link[rel="canonical"]')?.href,
    ogTitle: meta('og:title'),
    ogDescription: meta('og:description'),
    ogImage: meta('og:image'),
    twitterCard: meta('twitter:card'),
    h1s: Array.from(document.querySelectorAll('h1')).map(h => h.textContent.trim()),
    h2s: Array.from(document.querySelectorAll('h2')).map(h => h.textContent.trim()),
    imagesWithoutAlt: Array.from(document.querySelectorAll('img:not([alt])')).length,
    totalImages: document.querySelectorAll('img').length,
    lang: document.documentElement.lang,
    structuredData: Array.from(document.querySelectorAll('script[type="application/ld+json"]')).map(s => { try { return JSON.parse(s.textContent).['@type'] } catch { return 'invalid' } }),
    robotsMeta: meta('robots'),
    viewport: document.querySelector('meta[name="viewport"]')?.content,
  };
}
```

3. Check each category and flag issues:

**Title** — exists, 30-60 chars, contains keywords
**Description** — exists, 120-160 chars, compelling
**Headings** — exactly one h1, logical h2 structure
**Images** — all have alt text, descriptive not generic
**Open Graph** — og:title, og:description, og:image present
**Twitter Card** — twitter:card meta tag
**Canonical** — canonical URL set
**Structured Data** — valid JSON-LD present
**Language** — lang attribute on html
**Viewport** — meta viewport for mobile

4. Output:

```
## SEO Check: [URL]

**Score: 7/10**

### Issues
- Title too long (74 chars) — trim to under 60
- Missing meta description
- 4 of 12 images missing alt text
- No Twitter Card meta tags

- h1: "Welcome to MyApp" (1 h1, good)
- Open Graph: title, description, image all set
- Canonical URL: set correctly
- Structured Data: Organization schema found
- Language: en
- Viewport: configured for mobile
