Straight from Google…

"Google Sitemaps is an easy way for you to help improve your coverage in the Google index. It's a collaborative crawling system that enables you to communicate directly with Google to keep Google informed of all your web pages, and when you make changes to these pages.”

It's a free service. Here's the sign-up/log-in page. https://www.google.com/webmasters/sitemaps/login

The Sitemap Protocol allows you to inform search engines about URLs on your websites that are available for crawling. In its simplest form, a Sitemap that uses the Sitemap Protocol is an XML file that lists URLs for a site. The protocol was written to be highly scalable so it can accommodate sites of any size. It also enables webmasters to include additional information about each URL (when it was last updated; how often it changes; how important it is in relation to other URLs in the site) so that search engines can more intelligently crawl the site.

Within the past week alone I've received several email offers selling Google Site Map Software that generates the XML file needed for $150 to $200 a pop.

DO NOT buy this software! Why?

Because

Highly recommend this one! http://johannesmueller.com/gs/
