An example of some of the tools offered:

•	Crawl info: Make sure Google has access to your site and see when Googlebot last visited. View URLs that Google has had trouble crawling and why.
•	Robots.txt file validation: See if Google is having trouble with your file, and test out changes to that file before you change it on your server.
•	Website content: View top content from your site and see the words that other sites use to link to it.

If you haven't already, you owe it to your site to check out Google Webmaster Tools.
