1. Strategies for improving Web site performance Google Webmaster Tools + Google Analytics Marshall Breeding Director for Innovative Technologies and Research Vanderbilt University http://www.librarytechnology.org/

2. Abstract With the investments that libraries make in developing websites, it is critical to constantly measure use levels, discern patterns and trends, and spot hotspots and areas of strengths, as well as areas that aren’t working like you anticipated. Google Analytics, a free service offering a very sophisticated approach to website analytics, enables libraries to use methodologies well tuned in the ecommerce arena such as action-oriented web development and search engine optimization. Breeding demonstrates how he uses Google Analytics to assist in the management of sites such as Library Technology Guides, the Vanderbilt Television News Archive, and components of the Vanderbilt University Library’s web presence.
