Your sitemap is built using your store's primary domain. So, if your store's primary domain is busylittlebird.com, then your sitemap would be found at busylittlebird.com/sitemap.xml.
If you haven't already, you should take a look through our instructions on how to find and submit your sitemap. It should make things a lot clearer!
Hope this helps! :)
Thanks Sam, the app helped me to generate the sitemap page!

If you're looking for a Shopify app that will automatically generate a beautiful HTML sitemap for your store in seconds, you'll want to install Sitemap Builder. https://apps.shopify.com/sitemap-builder?ref=adolab
Sitemap Builder lists every product, collection, page, blog, and article on your entire site on one convenient page.

Sitemap Builder is better than other sitemap apps becuase it offers a free 1x design, 24/7 customer support, fully customizable layout & text, and there's no cap on the amount of products you want to list on there. It also has a 5 star rating, & is trusted by Shopify sellers who use it everyday to list hundreds of thousands of products.
