To help boost your site’s organic search rankings, be sure to create and submit a site map to Google. A small XML document, the site map helps ensure that the all-powerful Goolebot can effectively crawl your pages.
Creating a site map is simple. It is just a UTF-8 encoded text file in XML site map protocol that lists the URLs for your site. (Example) For a small site, you can create the file manually, or for larger, more complex sites, you can use the Google Sitemap Generator or a third-party tool.
Once you have your site map file, simply submit it to Google and provide a small amount of additional information about your site. You can then look at statistics and error information about your site.
Remember, the Web is not a "build it and they will come" phenomenon. To get the full benefit from this medium, you need to do everything you can to get your site "found."
