Recently I did one test with Yahoo and Google sitemaps and I would like to share my experience with others. I think it is interesting for other webmasters.
I have a website that contains 4 pages. 3 pages are crosslinked together and one page doesn’t have any links at all. Two weeks ago I have submitted my sitemap to Yahoo site explorer and to Google sitemaps (aka Webmaster Tools). All pages where listed within my sitemap. Today Yahoo’s site command shows all 4 pages and Google’s site command shows only 3 of them.
Conclusions are after you
