Google indexes the page using the domain alias I have a Drupal 8 page which is indexed from Google without any error. The front page is a node configured as a front page in the Basic site settings (admin/config/system/site-information) using the path alias /front or de/heim.  

The point is that the path alias for the front page should be the root (e.g. example.com) which is it. So, everything is working fine if I navigate the page.

Why is the path alias shown in Google search results, and not the root domain?  It shows example.com/en/front or example.com/de/heim, not example.com.

I have never seen this problem before using Drupal 6 or Drupal 7.
It really depends on what page Google finds first, I guess. So, I do now know.

However in order to overcome this, you would have used the global redirect in Drupal 7, which has been merged with Redirect. I have not tried it, but if it an exact port it should still be able to. 


  Checks if the current URL is the same as the site_frontpage and
  redirects to the frontpage if there is a match.
