Quick answers

Frequently asked questions.

What are return links?

If page A lists page B as its French version, B must list A as well. Google ignores hreflang pairs that do not link back to each other.

Is en-UK a valid code?

No. The region code for the United Kingdom is GB, so use en-GB. Region codes follow ISO 3166-1 and languages follow ISO 639-1.

Does it read hreflang in sitemaps?

No. It reads the HTML head and the HTTP Link header of the page. Hreflang in an XML sitemap is not checked here.
