Server Side Analytics
b2evolution comes with a built-in Server-Side Analytics feature which provides the system administrator as well as the blog owners with unique insights over the usage of their website / blogs.
Server-Side Analytics also play a role in Dynamic Antispam.
b2evolution will start recording hits on your blogs out of the box, without the need for any additional web stats or analytics package.
You can then see stats for all your blogs under the Analytics tab in the back office.
In addition to that, b2evolution 3.x+ also introduces Goal tracking.
