In addition to standard web analytics features — view detailed visitor information in real time on a world map, analyze historical information on visits, record events, and so on — Awesomelytics lets you retrieve visitor events on any of your properties from any of your other properties when you install the tracking code on multiple websites. This allows you to follow your users as they move between your sites and act on information gleaned on your other websites. Installation is straightforward and is documented for various platforms. A WordPress plugin is also available.
My short, sorry stint in SEO was the strangest job I've ever had. I was asked to create hundreds of imaginary webmasters and write little "About Me" biographies of their lives for fake blogs that only Google's webcrawlers were meant to read. They gave me the site name, I wrote the bio, and a coworker added manipulated photos. I did this for many months. I began to get bored... and then I began to get weird.
