Having an XML sitemap can be beneficial for SEO, as Google can retrieve essential pages of a website very fast, even if the internal linking of a site isn’t flawless. The sitemap index and individual sitemaps are updated automatically as you add or remove content.
1) After logging in, you'll see the SEO option in your Dashboard. Click General.
2) Click on the Features Tab.
3) Scroll down to the 'XML Sitemaps' and switch to 'On'.
4) Save changes.
5) View the XML Sitemap by clicking on the question park next to the XML sitemaps toggle.
A sitemap can also be viewed by adding /page-sitemap.xml to the end of your domain.
