New WebSideStory Study Reveals Conversion Rate for Each Major Search Engine

AOL Search Posts Best Order Conversion Rate Among Major Search Engines,

Followed by MSN, Yahoo and Google

SAN DIEGO, Feb. 15 /PRNewswire-FirstCall/ -- WebSideStory, Inc.
(Nasdaq: WSSI), a leading provider of on-demand digital marketing
applications, today reported the results of a new study showing the
median order conversion rate for the top four search engines. For the
month of January, AOL Search generated the best conversion rate at
business-to consumer e-commerce sites (6.17 percent), followed by MSN
(6.03 percent), Yahoo (4.07 percent) and Google (3.83 percent),
according to the WebSideStory Index, a new statistical barometer that
features techno-graphic and e-commerce trends culled from the millions
of users that visit web sites using the company's award-winning web
analytics technology, HBX Analytics. The study includes traffic from
both organic and paid keywords.

"One way to explain the difference in conversion rates is
demographics," said Ali Behnam, senior digital marketing consultant
for WebSideStory. "With portals rich in content and services, AOL, MSN
and Yahoo may tend to appeal toward a more buyer friendly demographic.
Google, meanwhile, may appeal to more browsers -- those with less of
an intent to buy."

"All of this suggests search engine marketers may want to consider
demographics in allocating their budgets," Behnam said.

Each of the major search engines posted conversion rates well above
the median average for all search engines, which was 1.97 percent for
the month of January, according to the index. This compares with a
median average of 2.30 percent for the last three months of 2005,
which WebSideStory reported on last month.

One other important consideration to note in this study, WebSideStory
officials said, is that the conversion rates are likely higher than
industry averages because the sample sites are using best-of-class web
analytics to improve their search engine marketing and optimization.
"Our clients are steeped in web analytics best practices and are not
buying search engine traffic that does not deliver," said Jeff
Lunsford, chairman and CEO of WebSideStory. "In addition, they
understand how to convert visitors into buyers once they arrive at the
site."

HBX Analytics is an award-winning, on-demand web analytics solution
that provides actionable information about online visitor customer
behavior. It is part of the WebSideStory Active Marketing Suite, the
industry's first suite of integrated, on-demand digital marketing
applications including web analytics, site search, web content
