# Add hreflang tags for multilingual sites
Without hreflang, users searching in French might see your English page—proper implementation ensures the right language version appears in search results for each region.
## Quick Reference
- hreflang tells search engines which language version to show users
- Always include x-default for fallback/language selector pages
- Must be reciprocal—all pages must link to all variations
- Use ISO 639-1 language codes and ISO 3166-1 Alpha-2 regions
## Check
Check if this multilingual website properly implements hreflang tags for language and regional targeting.
