Quasar is a Vue.js framework providing a cohesive toolchain and component set to build cross-platform apps from a single codebase, including SSR and PWA targets.

SEO depends on enabling SSR for public pages. With Quasar SSR mode, the server renders HTML which improves crawlability. PWA enhancements and image optimizations can further improve performance metrics.

Quasar ships a large, well-documented component library and CLI, reducing the need for disparate third-party packages. This improves consistency and maintainability.

International SEO Fundamentals

When targeting multiple countries or languages, proper international SEO ensures search engines serve the right content to the right audience. This involves URL structure, hreflang tags, and language detection.

• URL Structure Options: Choose between subdirectories (/en/, /fr/), subdomains (en.site.com), or parameters (?lang=en). Subdirectories are typically recommended for most sites.
• Hreflang Tags: HTML attributes that tell search engines about language and regional variations of your pages. Format: <link rel="alternate" hreflang="en-US" href="..." />
• Language vs Locale: Use language codes (en) for language targeting, or locale codes (en-US, en-GB) for region-specific content.

Implementing International SEO in Quasar

Quasar provides built-in i18n support through Quasar Language Packs and integrates seamlessly with vue-i18n for application-level translations.

• Routing Strategy: Structure your routes with language prefixes using Vue Router. Quasar SSR mode ensures these routes are pre-rendered with full HTML for crawlers.
• Adding Hreflang: Use Quasar's meta configuration in quasar.conf.js or dynamically inject hreflang tags in your layout using the useMeta composable.
• Recommended Tools: Quasar Language Packs (for UI components), vue-i18n (for app translations), @quasar/app-vite or @quasar/app-webpack (with SSR mode enabled).
• Code Example:

  // quasar.conf.js - Configure for SSR
  module.exports = function (ctx) {
    return {
      ssr: {
        pwa: false
      }
    }
  }
  
  // In a Vue component with Quasar
  import { useMeta } from 'quasar';
  import { useI18n } from 'vue-i18n';
  
  export default {
    setup() {
      const { locale } = useI18n();
      
      useMeta(() => ({
        htmlAttr: { lang: locale.value },
        link: [
          { rel: 'alternate', hreflang: 'en', href: 'https://site.com/en/about' },
          { rel: 'alternate', hreflang: 'fr', href: 'https://site.com/fr/about' },
          { rel: 'alternate', hreflang: 'x-default', href: 'https://site.com/en/about' }
        ]
      }));
    }
  }
