An XML sitemap supplies search engines with the canonical URLs a site wants to surface. It can aid discovery of new pages that are hard to find through links alone.
In the demo, a new URL joins the list and moves into a discovery queue. Inclusion does not guarantee crawling, indexing, or ranking. Remove deleted and noncanonical URLs from the file.
When to use
Use it to improve discovery when a site has many new or weakly linked pages.
