WebSideStory Called ‘The Solution for Getting the Most from E-Commerce’ by Independent U.K. Research Firm

Bloor Research Report Underscores WebSideStory’s Impressive Growth in the UK Market with More than 100 Enterprise Customers

LONDON (June 27, 2006) ¾ WebSideStory, Inc. (Nasdaq: WSSI), a leading provider of on-demand digital marketing solutions and real-time enterprise analytics solutions, today announced that it has been recognized by a leading independent U.K. research firm as having one of the most comprehensive solutions for meeting the needs of online marketers. In a June 15 report entitled, “WebSideStory – The Solution to Getting the Most from E-Commerce,” Bloor Research Analyst David Norris says the WebSideStory Active Marketing Suite – a suite of integrated, on-demand digital marketing applications including web analytics, site search, keyword bid management and web content management – is best suited for online marketers looking to “actively” manage their customer relationships as a way of increasing loyalty and sales.

“If you are looking at sales over the Internet as just a way to reduce overhead, and do not see your role as actively and dynamically ensuring that your site is attractive, easy to use and tailored to the needs of your customers, then this is not a product for you,” Norris writes in his report for Bloor Research, one of Europe’s leading independent IT research organizations (www.bloor-research.com).

The Active Marketing Suite enables marketers to better understand online visitor and customer behavior and optimize a broad range of online initiatives, from measuring online campaign performance to producing more relevant site search results. According to Norris, WebSideStory sets itself apart from the competition through its keen understanding of what marketers need to be successful, as well as the tight integration between its products, which enable marketers to leverage powerful synergies not available in stand-alone web analytics products.

“Individually there are competitors to each of these point solutions, but WebSideStory has them integrated into a unified whole, with documented APIs to enable the suite to be readily integrated into whatever workflow requires them,” Norris writes. “It is this integration which is the most powerful technical element of the solution; but the real strength of WebSideStory is their understanding and passion for what it means to actively market.”

The Bloor Research report comes amid impressive growth for WebSideStory in the UK market, where it currently has more than 100 enterprises spanning all four major business models: e-commerce, media, lead generation and self-service. Select UK customers include BSkyB, Littlewoods, LX-Direct, Guardian Unlimited, IWantOneofThose.com, Ladbrokes, News International, Norwich Union, Debenhams, and Mothercare. WebSideStory has more than 1,300 customers worldwide.

“We are pleased to be recognized by Bloor Research for our innovation and vision and look forward to the continued success of our many customers,” said Rand Schulman, Chief Active Marketing Officer for WebSideStory.
