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/

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.

Collection and Measurement n Multiple techniques n Server logs n Third party collection

Web server logs n Web servers are routinely configured to record detailed information about each request. Common elements include: – File requested – Date / time stamp – Status code – Request directive (get, post, head) – Referrer (where the user came from) – User agent (browser and platform data)

Exploiting referral data The query string component of the referrer can be parsed to reveal search terms and other interesting information n http: //www. google. com/search? hl=en&lr=&safe =off&q=september+11+television+archive n – User typed “september 11 television archive” in Google to find our site n n Important to study how users get to your site [example: TV News Public Web queries vs Open. Web)

Google Analytics Data n Does not use Web server logs n Based on data sent dynamically based on Google Web site n Complete URL – Including referral data n IP / Domain of requestor n Aggregated patterns of use n Personally identifiable data?

Analysis methodology n Go beyond simply counting pages n Identify Sessions n Categorize users n Determine use patterns n Measure interest – Time spent on Web site – Bounce rate – Page overlay analysis

Move from measurement to impact n Establish site goals n Benchmark current use n Implement goal oriented improvements n Measure impact n Repeat as needed n (Example: enhancement of TV News Open. Web)
