What is the x-default hreflang tag?

The x-default hreflang attribute tells search engines which page to serve when no specific language or regional version matches the user's browser settings (such as a global language selector page or international home page).

Must hreflang tags be bidirectional?

Yes! Google requires return links: if Page A links to Page B with a hreflang tag, Page B must reciprocate and link back to Page A. Failing to do so causes Googlebot to ignore the tags.

Should a page have a hreflang pointing to itself?

Yes. Every multi-language page must include a self-referential hreflang tag pointing to its own URL alongside tags pointing to the alternate language variations.

Frequently Asked Questions

Can I use country codes without a language code?

No. Google's specification requires a language code first. Specifying only a country code (like hreflang="us") is invalid; it must be en-us.

Should I put hreflang in HTML or the XML sitemap?

For smaller sites, putting tags directly in the HTML <head> is simple. For large multi-lingual stores with thousands of URLs, placing them in your XML sitemap avoids bloating page weight.

What happens if return links are missing?

If your English page points to your Spanish page, but the Spanish page does not point back to the English page, Google Search Console will flag a "no return tags" error and ignore the relationship.
