WebSideStory Recognized as Web Analytics Innovator

by Independent Research Firm

WebSideStory Is the First Vendor to Deliver on the Promise of an Online

Marketing Suite, According to Report

SAN DIEGO, Jan. 20 /PRNewswire-FirstCall/ -- WebSideStory, Inc.
(Nasdaq: WSSI) (www.websidestory.com), a leading provider of on-demand
digital marketing applications, today announced that it has been
recognized as an innovator in the web analytics market by an
independent technology research firm. In a report titled,
"WebSideStory HBX Innovates in the Web Analytics Market," Forrester
Research writes that WebSideStory is the first web analytics vendor to
deliver on the promise of an online marketing suite.

"The vendor is the first to pull together a set of technologies that
address the spectrum of site marketing needs spanning content
publishing, site search and keyword bid management," writes Nate Root,
Vice President and Research Director for Forrester Research, an
independent technology and market research firm based in Cambridge,
Mass.

According to the report, WebSideStory's vision of a marketing suite
knitted together by APIs (application programming interfaces) for
reporting and data access will pay off as the company builds out an
eco-system of strategic partners that can tap into the data and
features.

Last year, WebSideStory launched the Active Marketing Suite, the
industry's first suite of integrated, on-demand digital marketing
applications, including web analytics (HBX), site search, web content
management and keyword bid management (to be released early this
year). WebSideStory currently has more than 1,000 global enterprises
using its services to improve their online marketing and sales
initiatives. WebSideStory also offers the industry's most
comprehensive suite of documented APIs, which enable both partners and
customers to integrate their products, services and data with the
company's award-winning services. WebSideStory currently has more than
30 Stream API marketing partners, including leading e-mail service
providers, search engine marketing firms, behavioral targeting
companies and third-party ad-serving networks.

"WebSideStory is pleased to be recognized for its first-mover
advantage in delivering an online marketing suite, which we define as
three or more separate and distinct applications, not just additional
web analytics features," said Rand Schulman, Chief Marketing Officer
for WebSideStory. "Combined with our documented APIs and growing
partner eco-system, WebSideStory is clearly leading the way in this
fast-paced market."
