How do I use the Admin Toolbar Module for Drupal on-page SEO?

The Admin Toolbar Module https://www.drupal.org/project/admin_toolbar

The Admin Toolbar module gives you one-click access to Drupal 8 admin screens. It works like the drop-down and slide-out menu system that is so popular on the web. While I prefer the speed and ease-of-use of the Coffee module, there are times I need to see the hierarchy. The Admin Toolbar module provides that ability.

Install and Enable the Admin Toolbar Module for SEO

1. Install the Admin Toolbar module on your server.
2. Go to the Extend page: Click Manage > Extend (Coffee: “extend”) or visit http://yourDrupal8site.dev/admin/modules.
3. Select the checkbox next to “Admin Toolbar”.
4. Click the Install button at the bottom of the page. The Admin Toolbar module uses the Admin menu permissions. If you can access the Admin menu, then you have the permissions you need.
