Why a sitemap?. Sitemaps usually hint search engine crawlers about the URLs in your site, and when your provide optional information such as <priority>,<changefreq> and <lastmod>, they get a better notion of wich URLs in your website are more important to you. So with that thought in mind we fired up a script that lets you create a sitemap of your site in XML format, ready to be added to Google Sitemaps ( you’ll need to create an account which is free). Even if you don’t add it to Google Sitemaps, you can just upload it to the root folder on your webserver and that’s it. The protocol is supported by the major search engines like Google,Yahoo and MSN. More info can be obtained on the sitemaps website.
