Google Analytics is an free internet program run by Google. It tell you information, such as, how many people visit your blog, what countries they are visiting from, what sites on your blog they visit, there time on your blog and many many many other things. My favorite application on the Analytics page is the choice to view "Traffic Sources", this gives the web masters the opportunity see how people stumbled across their websites. Traffic Sources also tells the owner what key works people have searched to locate your website.
