Omniture the Only Solution Flexible Enough to Meet the Business Needs of Leading Educational Publisher

OREM, Utah – August 16, 2006 – Omniture, Inc. (NASDAQ: OMTR), a leading provider of online business optimization software, today announced Encyclopaedia Britannica has selected Omniture SiteCatalyst® to enhance the effectiveness of their online marketing initiatives. With Omniture, Encyclopaedia Britannica will be able to gain insight about visitors coming to their online product offerings at Britannica.com and EB.com to better understand their needs, and as a result, deliver a more compelling and relevant consumer experience.

“As new generations come to the Internet to conduct research, it’s becoming more and more important to really understand how people are engaging with our content,” said Dan Smith, senior vice president of consumer marketing at Encyclopaedia Britannica. “With SiteCatalyst, we will now be able to accurately determine how to best align our rich databases of content with our users’ preferences—while also gaining insight into the return on investment of our online marketing campaigns.”

A key reason Encyclopaedia Britannica selected Omniture was the solution’s versatility. During their Web analytics vendor evaluation process, Smith’s team noticed most solutions offered functionality primarily designed to focus on retail and ecommerce—which didn’t address Encyclopaedia Britannica’s electronic publishing needs including the optimization of subscriptions, renewals and other consumer engagement transactions. According to Smith, Omniture was the only option flexible enough to meet their needs.

“The inherent flexibility of the SiteCatalyst architecture, coupled with our depth of experience working with the world’s top media and publishing companies provides significant benefits for Encyclopaedia Britannica,” said Gail Ennis, senior vice president of marketing at Omniture. “Supplying reporting, dashboards, implementation assistance and best practices tailored to their unique business model allows them to achieve faster time-to-value.”
