Quick Start (5 Minutes)

1. Install Complete SEO Bundle

Install all 8 modules at once:

# 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:

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

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)

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

Configuration:

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

Option 2: Individual Modules

Install only what's needed:

# 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:

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

// 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:

• 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
