I read somewhere that the any sitemap files linked to in a website should be removed temporarily so as to prevent the sitemap generator from indexing itself. When I ran the free generator, the xml sitemap.com generator report said I had one broken link. That broken link trurned out to be the sitemap.htm file I temporarily removed. So I reinstalled the sitemap.html and renamed it Sitemap.htm, and ran the free xml sitemap generator again. Now no broken links show, but the sitemap.html pages that humans see went from 80 kb to 234 kb and the docs went from 83 kb to 165 kb. The sitemap.xml file went from 43 kb to 82 kb. This seems like unnecessary duplication, and I don't want a Google penalty.
thank you,
