📚 hreflang Complete Guide

🔹 What is hreflang?

hreflang is an HTML attribute that tells Google which language and region a page targets. It prevents duplicate content issues for multilingual sites and helps show the right page to the right user.

🔹 When to use hreflang?

Same content in multiple languages (English + French + Spanish)
Same language targeting different regions (en-US + en-GB + en-AU)
Pages with alternate regional currencies or formats

🔹 Common Language Codes

🔹 Implementation Methods

1. HTML <head> — Most common. Add link tags inside <head> on every page version.

2. XML Sitemap — Best for large sites. Add alternate entries in your sitemap.xml.

3. HTTP Headers — For non-HTML files (PDF, etc.). Set via server configuration.

🔹 Critical Rules

✅ hreflang must be bidirectional — page A must reference page B AND page B must reference page A
✅ Always include x-default as fallback for unmatched regions
✅ Each page must reference itself in the hreflang list
✅ Use correct ISO 639-1 language codes (en, fr, de, zh)
✅ Use correct ISO 3166-1 region codes (US, GB, CN, AU)
❌ Don't use hreflang for pagination or different content types
❌ Don't mix language and region codes incorrectly (e.g., en-FR = English content in France)

🔹 Common Mistakes

❌ Missing self-referencing — Every page in the set must include a tag pointing to itself.

❌ Missing x-default — Without x-default, Google may not know what to show to users in uncovered regions.

❌ Non-canonical URLs — Always use absolute, canonical URLs in hreflang tags.

❌ Wrong language codes — Use zh-Hans for Simplified Chinese, not zh-CN. Use pt-BR for Brazilian Portuguese.
