It was recently announced that Yahoo, Google and MSN will all be using the same format for site maps, a format based on the Google sitemap. Most people think that a good site map will help your site get increased search engine rankings, but according to Google, that is not the case. According to Vanessa Fox from Google, sitemaps don’t affect rankings at all, they are merely a way of ensuring your pages are being picked up. The site map is a tool to help search engine crawlers access more pages.  So put a site map on your website, but don’t expect it to increase sales. In order to do that you have to generate fresh content and back links. The quickest way to do that is with a company blog, viral marketing and video optimization.
