Submit Sitemap With Robots.txt (to which all the major engines now subscribe) sets a standard for referencing that utilizes the very same robots.txt file. When a spider visits your site and reads your robots.txt file, you can now tell it where to find your sitemap For example (where your sitemap file is called sitemap.xml and is located in the root of your website):
User-agent: *
Disallow: /cgi-bin/

The example robots.txt file tells the crawler how to find your sitemap and not to crawl either your cgi-bin directory (containing PERL scripts not intended for the human reader) or your images directory (to save bandwidth).
