I tried setting up my sitemap and I got back an error. Does it supposed to do that? Is there an easier way to get a sitemap for my blogger blog?
If you have a atom RSS feed on your blogger's blog (if not then you can add it from the page layout section), the default sitemap for the blog would be www.xyz.blogspot.com/atom.xml. This is the site that you need to submit in Google webmaster tool. If you have done that and still getting the error, please share the error message with us. Some times it takes more than one try for it to be accepted by Google, so go for it.
