The “new” version of Google Analytics has several new reports that are worth studying. One report I like is the “site speed” report which is newly available in Google Analytics… it simply tells you how fast your website loads on average and also breaks down specific pages for analysis.
In order to make this new feature work you have to add a snippet of code to your tracking scripts: “_gaq.push(['_trackPageLoadTime']);” You can read all about how site speed works and how to add the tracking script on the Google Analytics Blog.
The other 90 second improvement I made to my Google Analytics reporting was to integrate it with my existing Google Webmaster Tools account.
Both these steps are worth the few seconds required!
