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 us informed of all your web pages, and when you make changes to these pages.
With Google Sitemaps you get:
* Better crawl coverage to help people find more of your web pages
* Fresher search results
* A smarter crawl because you can provide specific information about all your web pages, such as when a page was last modified or how frequently a page changes
