Organic CEO Mark Kingdon to Deliver Keynote on Using HBX Analytics to Track AJAX, RSS Feeds for DaimlerChrysler

LONDON (Sept. 14, 2006) WebSideStory, Inc. (Nasdaq: WSSI), a leading provider of digital marketing and analytics solutions, today announced that it will highlight its industry leading Web 2.0 capabilities as part of its ActiveInsights user forum Oct. 3-5 at the Crowne Plaza in New York City. WebSideStory CEO Jeff Lunsford, Organic CEO Mark Kingdon and industry leading customers and partners will demonstrate, among other things, how WebSideStory is not only leading the industry in tracking Web 2.0-enabling technologies, but also using these technologies to maximize the performance and capabilities of its own enterprise applications. Kingdon will deliver the keynote address, entitled “Overcoming Blind Spots: Understanding Engagement Metrics in a Web 2.0 Universe,” focusing on how the advent of AJAX, RSS feeds, Flash, online video and other Web 2.0 technologies are changing the way people interact with the web, and how standard HTML-focused web analytics solutions are creating “blind spots” for marketers. Kingdon will present a case study on how HBX Analytics helped his interactive marketing firm overcome these obstacles, including tracking and optimizing an AJAX and RSS-intensive project for DaimlerChrysler, a joint customer. More than 500 people are expected to attend the three-day event.

“This is a very exciting time in our industry. As emerging Web technologies evolve, they are enabling more complex and immersive consumer experiences—such as what we’re seeing in social networking and online video,” Kingdon said. “Together with WebSideStory, we are helping our clients see a more complete picture of consumer behavior in the Web 2.0 universe. This case study is a perfect example of that. To help us achieve DaimlerChrysler’s objectives, we needed to use technologies that were outside the capabilities of most web analytics solutions, except for WebSideStory, which continues to innovate ahead of the market.”

WebSideStory will highlight all of its industry leading Web 2.0 capabilities at the three-day event. They include:

• Tracking Web 2.0 content and applications – HBX Analytics can easily track visitor interaction with applications created in AJAX (Asynchronous JavaScript and XML) and Flash, as well as the use of RSS feeds (Really Simple Syndication), podcasts and blogs. In April 2006, WebSideStory became the first vendor to offer tracking of streaming media and mobile device usage as standard capabilities.

• Using Ajax to optimize WebSideStory’s own applications for customers – In addition to tracking Web 2.0 technologies, WebSideStory is using this technology (specifically AJAX) to improve the performance and capabilities of its own enterprise applications. An upcoming industry first capability in this area will help customers enhance the visitor experience and increase conversions.

• “Enterprise mash-ups” powered by WebSideStory’s comprehensive APIs – Thanks to its suite of documented APIs (application programming interfaces), WebSideStory has delivered the industry’s first suite of integrated on-demand digital marketing applications, including web analytics, site search, web content management and keyword bid management. This integration, referred to as “enterprise mash-ups,” enables customers to leverage the strong synergies between different applications, such as using web analytics to power site search results. The APIs also enable customers to integrate their web analytics data with key partner marketing applications. These mash-ups are an integral part of Web 2.0, according to industry columnists such as ZDNet blogger Phil Wainewright.

“Our Web 2.0 initiative encompasses everything from tracking new technologies such as AJAX, to using our APIs to create integrated solutions that deliver powerful results for our customers,” said Rand Schulman, Chief Marketing Officer for WebSideStory. “WebSideStory has a long history of innovation and we are proud to work with companies such as Organic in bringing these capabilities to the market. Web 2.0 is no longer just a buzzword, it is a real set of technologies that are changing the web in significant ways.”

ActiveInsights is open to all customers of WebSideStory’s suite of integrated digital marketing applications. The event includes customer success stories, best practice sessions, product training, a partner pavilion, networking events and more. WebSideStory will also offer one-on-one consultations in the product gallery where it will showcase its product suite, as well as its Web 2.0 capabilities.
