Hot on the heels of Google Analytics Intelligence, Google has now added another really cool feature Annotations. This is another great addition and makes it easier to share collaborative knowledge around change in traffic patterns. Annotations allow users to add notes against stand out traffic patterns.

If you are a large company that has multiple departments, trying to work out what caused a spike or dip in traffic can be a real pain. Now you can have one standard login and allow teams to add notes against relevant dates. This will allow you to match up any online or offline activity against changes in traffic. Pretty cool !!!
