There is a new tool from Google that you should be aware of if you are trying to naturally optimize your website for the search engines. (If all of that was Greek to you then talk to your webmaster or get one ;). It is called Google Sitemaps.
According to Google it "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. "
Basically, instead of waiting for Google to "crawl" your site when you make changes, using Sitemaps you let Google know of any changes directly.
It's free, and my guess is if you don't start using it, your competition will, and you will fall behind.
