To be more specific: Tying in a/b testing with user flows and analytics like - ranking pages by abandon rate so you can see where your loosing people - tracking funnel processes like sign up and shopping cart to identify problem areas - ranking links based on clicks to show what users really care about and what is just taking up space on a page - enabling exit interviews and real-time chat with users to collect feedback - and on top of identifying problems it would be really useful for it to present suggestions to help solve the problems.
Analytics are just a means to an end but for some reason analytics companies think analytics are the end. Big disconnect here as most of their customers don't have the sophistication to take the analytics and know how to improve their site from them. The analytics company that provides an idiots guide to fixing problem areas and optimizing your site will be a game changer.
