seo – Google is de-indexing our desktop site after launching a separate mobile site with fewer pages

For pages where you have desktop and mobile versions of the page:

  • In you page, put a canonical pointing to the page and a alternate pointing to the page.

  • In you page, put a canonical pointing to the page.

For pages where you only have a desktop version:

  • In you page, put a canonical aiming at page and do not use a alternate label (because there is no alternative representation).

  • Leave your Page non-existent.

This configuration ensures that Google will always index your pages as canonical pages and they will not be confused and will index any pages, because you will see them as an alternative resource representation.

When a visitor visits your page, detect if they are on a mobile device. If both are on a mobile device and you also have a mobile representation of the page you are viewing, redirect them to the Version of the page.
