SAN DIEGO, CA (Feb. 15, 2006)—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 management and, later this year, keyword bid management.
