Google Analytics

I've noticed that a lot of people use AdWords/AdSense with their blog to either make money or advertise. In my internet stumblings (which I'm so prone to do), I came across Google Analytics. I was blown away by the detail of everything.

• You can track where people enter and exit your site.
• You can track Referring links.
• What browser people use.
• Heck, you can even see what screen resolution they were running!
• There is also a content breakdown section to see which pages are the most popular.
• There is even an option on to show an overlay of your site (The website as people see) with little graphs next to each link to show how many times people have clicked on that specific link.
