hi i have one domain and i parked it my blog and verify it on google webmaster tools yesterday i buy host and and i parked this domain on my new site and submit this site on GWT know when i want to submit my sitemaps on google i got this problems
When you say "parked," do you mean hosted, not "parked"? Parked domains don't have pages, there is no need for a sitemap. So you have moved your site to a new host? It seems to me that you took your old sitemap and simply moved it to the new host, without changing it. But your old URLs no longer work or no longer apply to this site, so you are getting 404 errors when Googlebot tries to crawl your site according to your sitemap. Proposed solution: regenerate your sitemap and resubmit. You can use xml-sitemaps.com to do so, for example.
As far as I concerned about this, you stated that you're using Blog (Blogger) so how can you ad a page something like "/post.xml" instead of "domain.com/p/post.html" or "domain.com/2013/11/post.html". The only way to Submit Sitemap on Webmaster for your Blogger Blog is: Click on "Add/Test Sitemap" on Webmaster Sitemap section and past following atom.xml?redirect=false&start-index=1&max-results=500 Code (markup): (Where 500 indicates number of posts, if your website has less then 500 then leave it as it is, if more than 500 so, Add another sitemape. atom.xml?redirect=false&start-index=501&max-results=1000 Code (markup): That's the method of adding Sitemap for Blogger.
