Frequently asked questions
What is x-default for?
The x-default hreflang value points search engines to the page to show when no other language matches the visitor's settings, such as a language selector.
What format should each line use?
Each line is a language or region code followed by its URL, for example 'en-us https://example.com/' separated by a space.
