I routinely submit the sitemap.xml file generated by NOF to Google on their Webmaster site. I also use the search box feature that NOF provides with both web and site options. Many times when I search my site for a term, I see among the site search results the sitemap.xml file. Two questions:
1) Why is sitemap.xml showing up in search results?
2) We changed our site structure over a year ago and have submitted updated sitemap.xml files to Google. Yet they still crawl, and report 404 errors, for pages that no longer exist and are not in the sitemap. Why?
