XML Sitemap

Your sitemap for the search engines does not have to be a fancy xml document. It can be as simple as a list of urls. A simple text file containing all the url’s within your website is all you need for a bare bones simple sitemap.
Something like.
http://www.example.com/contact.htm
http://www.example.com/about.htm
http://www.example.com/sales.htm
http://www.example.com/products.htm
will work just fine.

How to reference your sitemap in your robots.txt file
An easy way to point the search engines to your newly created sitemap is to place a reference inside your robots.txt file.
Simple add the following line to your robots.txt file, insert your own domain name and name of your sitemap file.
Sitemap: http://www.example.com/sitemap.xml
