Hello, I want to know something, I have created an XML Sitemap when I made my blog about 7 days ago, the sitemap which I have created on Google, Bing and Yahoo is 'sitemap.xml'. I want to know if it is necessary to create one or WordPress automatically added it on the webmaster tool of these search engines websites? Because I have noticed another sitemap has been added not by me when I click on 'All' on Google webmaster tool's sitemap table and it has 0 URLs indexed on web whereas mine has 19 indexed. Thank you.
The blog I need help with is mysteryworlds.wordpress.com.
