---

## Quick Start (5 Minutes)

### 1. Install Complete SEO Bundle

Install all 8 modules at once:

```bash
# Using Bun (primary)
bunx nuxi module add @nuxtjs/seo

# Using npm (backup)
npx nuxi module add @nuxtjs/seo

# Using pnpm (backup)
pnpm dlx nuxi module add @nuxtjs/seo
```

**Why this matters:**
- Installs all 8 modules with a single command
- Ensures compatible versions across modules
- Provides best-practice defaults automatically

### 2. Configure Site Settings

Add to `nuxt.config.ts`:

```typescript
export default defineNuxtConfig({
  modules: ['@nuxtjs/seo'],

  site: {
    url: 'https://example.com',
    name: 'My Awesome Site',
    description: 'Building amazing web experiences',
    defaultLocale: 'en'
  }
})
```

**CRITICAL:**
- Set `site.url` to production URL (required for sitemaps and canonical URLs)
- Use environment variable for multi-environment setups
- Set `defaultLocale` if using i18n

### 3. Restart and Verify

```bash
bun run dev
# or
npm run dev
```

Visit these URLs to verify:
- `http://localhost:3000/robots.txt` - Robots file
- `http://localhost:3000/sitemap.xml` - Sitemap

---

## Installation Options

### Option 1: Complete Bundle (Recommended)

```bash
bunx nuxi module add @nuxtjs/seo
# or: npx nuxi module add @nuxtjs/seo
```

Configuration:

```typescript
export default defineNuxtConfig({
  modules: ['@nuxtjs/seo']
})
```

### Option 2: Individual Modules

Install only what's needed:

```bash
# Bun
bunx nuxi module add nuxt-robots
bunx nuxi module add nuxt-sitemap
bunx nuxi module add nuxt-og-image

# npm
npx nuxi module add nuxt-robots
npx nuxi module add nuxt-sitemap
npx nuxi module add nuxt-og-image

# pnpm (backup)
pnpm dlx nuxi module add nuxt-robots
pnpm dlx nuxi module add nuxt-sitemap
pnpm dlx nuxi module add nuxt-og-image
```

Configuration:

```typescript
export default defineNuxtConfig({
  modules: [
    'nuxt-robots',
    'nuxt-sitemap',
    'nuxt-og-image'
  ]
})
```

## Module Overview (Brief)

The Nuxt SEO ecosystem consists of **8 specialized modules** that work together seamlessly. Each module serves a specific purpose and can be installed individually or as a complete bundle.

### Module 1: @nuxtjs/seo
Primary SEO module that installs all 8 modules as a bundle. Provides unified configuration through the `site` object and integrates with Nuxt Content for automatic SEO.

### Module 2: nuxt-robots
Manages robots.txt and bot detection. Controls which pages search engines can crawl with site-wide and page-level rules. Includes server-side and client-side bot detection.

### Module 3: nuxt-sitemap
Generates XML sitemaps automatically from routes with support for dynamic URLs, multiple sitemaps, media, and advanced optimization. Perfect for large sites with thousands of pages.

### Module 4: nuxt-og-image
Creates Open Graph images dynamically using Vue templates. Zero runtime overhead with Satori renderer or full CSS support with Chromium renderer.

### Module 5: nuxt-schema-org
Builds Schema.org structured data for enhanced search results with rich snippets, knowledge panels, and better SEO.

### Module 6: nuxt-link-checker
Finds and fixes links that may negatively affect SEO. Detects broken links, redirects, and issues during development and build.

### Module 7: nuxt-seo-utils
SEO utilities for discoverability and shareability including canonical URLs, breadcrumbs, app icons, and Open Graph automation.

### Module 8: nuxt-site-config
Centralized site configuration management for all SEO modules. Single source of truth for site-wide settings like URL, name, and locale.

## Integration Patterns

### Basic Example

```typescript
// nuxt.config.ts - Complete SEO setup
export default defineNuxtConfig({
  modules: ['@nuxtjs/seo'],

  site: {
    url: 'https://example.com',
    name: 'My Awesome Site',
    defaultLocale: 'en'
  },

  robots: {
    disallow: ['/admin']
  },

  sitemap: {
    sitemaps: {
      blog: { sources: ['/api/__sitemap__/blog'] }
    }
  }
})
```

**For complete integration examples:**  
Load `references/common-patterns.md` when you need:
- Blog page SEO implementation
- E-commerce product page examples
- Multi-language SEO patterns
- Integration with Nuxt Content
## Critical Rules

### Always Do

✅ Set `site.url` in nuxt.config.ts (required for sitemaps and canonical URLs)
✅ Use environment variables for multi-environment setups
✅ Configure robots.txt to block admin/private pages
✅ Add Schema.org structured data to all important pages
✅ Generate OG images for social sharing
✅ Test all SEO features before deploying to production
✅ Submit sitemap to Google Search Console after deployment
✅ Enable link checker during development

### Never Do

❌ Forget to set `site.url` (breaks sitemaps and canonical URLs)
❌ Allow crawling of staging environments
❌ Skip Schema.org for key pages (products, articles, events)
❌ Deploy without testing OG images
❌ Use outdated module versions
❌ Ignore broken links found by link checker
❌ Forget to exclude admin/private routes from sitemap
❌ Use wrong rendering engine for OG images (Chromium vs Satori)

## Known Issues Prevention

This skill prevents **10** documented common SEO mistakes:

### Issue #1: Sitemap Not Generating

**Error**: `/sitemap.xml` returns 404
**Why It Happens**: Missing `site.url` configuration
**Prevention**: Always set `site.url` in nuxt.config.ts

### Issue #2: robots.txt Missing

**Error**: `/robots.txt` not accessible
**Why It Happens**: Module not installed or misconfigured
**Prevention**: Install `nuxt-robots` and set `site.url`

### Issue #3: OG Images Not Rendering

**Error**: `/__og-image__/og.png` returns error
**Why It Happens**: Incompatible CSS with Satori renderer
**Prevention**: Use Satori-compatible CSS or switch to Chromium renderer

### Issue #4: Schema Validation Errors

**Error**: Invalid JSON-LD in page source
**Why It Happens**: Incorrect Schema.org structure
**Prevention**: Follow official Schema.org types and validate with Google's Rich Results Test

### Issue #5: Broken Internal Links

**Error**: 404 errors on internal links
**Why It Happens**: Links not updated after route changes
**Prevention**: Enable `nuxt-link-checker` during development

### Issue #6: Duplicate Meta Tags

**Error**: Multiple meta tags with same property
**Why It Happens**: Conflicting manual meta tags and module automation
**Prevention**: Let modules handle meta tags automatically

### Issue #7: Canonical URL Issues

**Error**: Wrong canonical URL in meta tags
**Why It Happens**: Incorrect `site.url` or missing trailing slash config
**Prevention**: Configure `site.url` and `trailingSlash` correctly

### Issue #8: Sitemap Index Errors

**Error**: Sitemap index XML malformed
**Why It Happens**: Too many URLs in single sitemap
**Prevention**: Use `chunksSize` option to split large sitemaps

### Issue #9: Crawling Staging Environment

**Error**: Staging site indexed by Google
**Why It Happens**: No robots.txt blocking
**Prevention**: Configure robots to block staging: `disallow: process.env.NUXT_PUBLIC_ENV === 'staging' ? ['/'] : []`

### Issue #10: Missing Social Sharing Images

**Error**: No preview image when sharing on social media
**Why It Happens**: OG image not defined or not accessible
**Prevention**: Use `defineOgImage()` on all important pages

---

export default defineNuxtConfig({
