Simple XML sitemap generates multilingual XML sitemaps which adhere to Google's new hreflang standard and provides a framework for developing other sitemap types.

Out of the box the sitemaps index most of Drupal's content entity types including:

• nodes
• taxonomy terms
• menu links
• users
• ...

Contributed entity types like commerce products or media entities can be indexed as well. On top of that custom links can be added to the sitemap.
