Nuxt SEO v5

Status: Production Ready | Dependencies: Nuxt >=3.0.0

Use this skill when building SEO-optimized Nuxt applications with any combination of the 8 official Nuxt SEO modules plus standalone modules.

Quick Start (5 Minutes)

1. Install Complete SEO Bundle

# Recommended (v5)
npx nuxt module add @nuxtjs/seo

2. Configure Site Settings

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

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

CRITICAL (v5 Breaking Change):

• site.name is NO LONGER auto-inferred from package.json — set it explicitly
• Set site.url to production URL (required for sitemaps and canonical URLs)
• Set defaultLocale if using i18n

3. Restart and Verify

Visit these URLs to verify:

• /robots.txt - Robots file
• /sitemap.xml - Sitemap
• /__robots__/debug-production.json - Debug (v5)
• /__sitemap__/debug-production.json - Debug (v5)

Individual Module Install

npx nuxt module add @nuxtjs/robots
npx nuxt module add @nuxtjs/sitemap
npx nuxt module add nuxt-og-image

Critical Rules

Always Do

• Set site.url AND site.name explicitly in nuxt.config.ts (v5: name no longer auto-inferred)
• 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
• Use getSiteConfig(event) on server side (v5: useSiteConfig(event) removed)
• Use defineSitemapSchema() for Content v3 (v5: asSitemapCollection() deprecated)

Never Do

• Forget to set site.url and site.name (breaks sitemaps, canonical URLs, titles)
• Allow crawling of staging environments
• Use useSiteConfig(event) on server side (v5: use getSiteConfig(event))
• Use asSitemapCollection() (v5: use defineSitemapSchema())
• Use getSiteIndexable() (v5: use { indexable } = getSiteConfig(event))
