Today at the eMetrics Summit in Washington, D.C., Google Analytics™ web service announced new enterprise-class features including custom reports, advanced segmentation, an API, as well as an updated interface, richer data visualizations, and an integration with Google AdSense™. These new features combine the sophistication and versatility of a full-service web analytics tool with Google Analytics’ ease of use and accessibility, so that businesses large and small, around the world, can even better serve their visitors.

Custom reports enable customers to create their own reports with the metrics they want to compare—organized in the way they want to see it.

Advanced segmentation enables customers to isolate and analyze subsets of their traffic. They can select from predefined custom segments such as “Paid Traffic” and “Visits with Conversions,” or create their own segments with a flexible, easy-to-use segment builder.

With Google Analytics’ new custom reporting and advanced segmentation, we have been able to use enterprise-class analytics to gain insight into site activity and take action on behalf of our clients to improve campaign ROI,” said Jeff Campbell, Co-founder and VP of Product Development for search marketing agency Resolution Media. “It’s a full-service tool that is still easy to use, and it’s free, which, given the current economic situation, is a huge benefit.”

The application programming interface (API), currently in private beta, enables developers to access all of their Google Analytics data and export it for any type of use. Possible uses include integrating information into other data sources, building custom visualizations or interfaces, and conducting offline analysis.

The updated interface includes several new features in the administrative interface and a cleaner reporting screen that highlights tools for changing the way reports display data. A new navigation, administrators’ ability to rename accounts and profiles, and account and profile locator functionality are designed to help increase customers’ efficiency and ease of account management.

Motion Charts provide advanced but easy-to-use multi-dimensional analysis. Customers can select their own metrics to compare and then view how those metrics interact over time. By animating data, Motion Charts make discovering insights much easier and more obvious than when viewing data in traditional graphs and columns.
