 Install and Enable the Sitemap Module

  1. Install the Sitemap module on your server. (See Chapter 1 for more instructions on installing modules.)
  2. Go to the Extend page: Click Manage > Extend (Coffee: “extend”) or visit http://yourDrupal8site.dev/admin/modules in your browser. 3. Select the checkbox next to “Sitemap” and click the Install button at the bottom of the page.

Configure the Sitemap module

  1. Click Manage > Configuration > Search and metadata > Sitemap (Coffee: “sitemap”) or visit http://yourDrupal8site.dev/admin/config/search/sitemap in your browser.
  2. Set the Page title using some keywords or your site name.
  3. Select the appropriate checkboxes under Menus to include in the Sitemap. Likely your Main navigation or any other visitor-facing menus.
  4. Under Vocabularies to include in the sitemap, select your main categories and Tags if you have them.
  5. Under Sitemap Settings, select the “Show titles” checkbox. 6. Click the Save configuration button at the bottom of the page.

You can view the sitemap at http://yourDrupal8site.dev/sitemap. The little orange icons next to each section are links to RSS feeds. Visitors who want to subscribe to your site and return when you’ve published new content will use that link in their newsreader applications.
