Google Analytics
Many schools and students are using Google Sites extensively to publish web-based content. Interested in knowing where your site's traffic is coming from or how people navigate around your site? You can now add Google Analytics to your site to help monitor its traffic. Once you've added a simple tracking ID to your site, all of the data collection happens automatically in the background. Google Analytics provides your school and students with a great series of dashboards showing valuable data about your audience. It's a great way to introduce real-world, meaningful statistical information around content you've produced.
