Do you have a robots.txt file set up on your server?
Here’s what Google says in their Webmaster Guidelines:
Make use of the robots.txt file on your web server. This file tells crawlers which directories can or cannot be crawled. Make sure it’s current for your site so that you don’t accidentally block the Googlebot crawler.

Google has always strived to give the end user the best and most appropriate results for the end user and has managed this very successfully and will continue to do so. Google Analytics was launched to give webmasters the ability to track websites via a small piece of java code that Google will track for you and give you the most accurate stats it can for your websites. Well it has just got better.
You can now track multiple data points in one graph, track downloads, track specific pages and much much more. Google have released this in beta mode for all users, one thing you will need to do is remove the old urchin.js code and replace it with the new ga.js code.
