I went to google.com/webmasters/tools, to submit sitemap of my blogs, 4 in total, while submitting it's just asking me to give the RSS feed URL, to be considered as a sitemap, I went to feedburner, found my feed link, submitted it into google, two got approved successfully, and two were told there's some error, I deleted the sitemap, and submitted again, still same errors, I even used another google account to submit these two sitemap, same bad result... What could be the problem? How could I solve it? Thanks and good day!
Think about the process, if the processes are the same, there should not be such a problem. In addition to the details about the problem!
