Google launched a new program called Google Sitemaps last night. It’s basically the same as Yahoo’s Paid Inclusion – but free. The program allows for webmasters feed pages to Google for inclusion into the index for free. Webmasters need to create an XML feed to participate in the program and at the moment there is only a Sitemap Generator using python.
