I am not sure if I understand how to use hreflang="x-default"
I have a website with two languages. In the head of each page I have a link to each language. For instance:
<link rel="alternate" hreflang="en" href="http://example.com/about" /> <link rel="alternate" hreflang="fr" href="http://example.com/fr/about" />
I have the page "language" To help people choose the language. It has two buttons. One to go to the home page in English and the other button to go to the home page in French.
Do I need to include in each page a link to "language"?
<link rel="alternate" hreflang="x-default" href="http://example.com/language" />
