News Release Details

SEATTLE, WA and NEW YORK, NY -July 10, 2007 -

IndustryBrains, the founder of site- specific contextual advertising and a wholly owned subsidiary of Marchex, Inc. (NASDAQ: MCHX, MCHXP), today announced that it has renewed and expanded its contextual advertising agreement with The Motley Fool, a leading investment advisory services company in IndustryBrains' Business & Finance vertical, which also includes BusinessWeek Online, Smartmoney.com, and Morningstar.com. At the same time, IndustryBrains announced that is has added a new premium publishing partner in National Golf Network (www.ngn.com), the official Web site of Golf Intelligence, connecting millions of golfers with golf courses, clubs, golf associations, PGA professionals, and other golfing resources.

Under the expanded Motley Fool agreement, IndustryBrains will continue to provide its contextual advertising solutions to The Motley Fool's primary Web site, while extending its services to the Motley Fool's popular financial discussion boards, which receive an average of more than 26 million page views per month, according to the Motley Fool. Additionally, IndustryBrains will also provide its solutions to Motley Fool CAPS, a ground-breaking stock rating service, now in beta, that enables users to get insights from the stock trading community and see how their picks perform compared with those of professional Wall Street analysts.

"As we expand The Motley Fool's offerings to areas like the new CAPS service, it makes sense to similarly extend our relationship with IndustryBrains, which has consistently provided us with a superior combination of results, client service, and useful solutions that positively impact our bottom line," said Gary Hill, Senior Vice President of Business Development at The Motley Fool.

"It is very gratifying that The Motley Fool, one of the Internet's leading sources for financial information, decided to expand our relationship and we look forward to helping them benefit from their expanded use of site-specific contextual advertising, whether on discussion boards or their innovative CAPS service," said Erik Matlick, IndustryBrains CEO. "We are also very pleased to welcome another new high quality publishing partner in National Golf Network, a site that exemplifies the convergence of high quality advertisers and consumers."

IndustryBrains founded the site-specific approach to contextual advertising more than five years ago, with the 2002 launch of its contextual advertising platform. IndustryBrains enables advertisers to place their product or service listings directly on premium Web sites and/or on specific sections or pages of such sites, based on relevance. This approach allows brand-name publishers to directly benefit from the value of their respective online brands, content and site traffic. The agreements announced today strengthen IndustryBrains' network of more than 100 vertically focused and brand-name online publishers, such as BusinessWeek Online, The Motley Fool, and the Ziff Davis online properties; which is paired with a large base of premier advertisers.
