News Release Details

SEATTLE, WA and NEW YORK, NY - February 20, 2007

Marchex, Inc. (NASDAQ: MCHX, MCHXP), in conjunction with its subsidiary IndustryBrains, today announced that since January 1, 2007, it has signed contextual advertising agreements with seven publishers across several vertical categories, including Business & Finance, Information Technology, and Home & Living. These publishers include InvestorVillage.com, Homes and Land, CIO Index.com, and WorldGolf.com, among others.

Under the agreements, Marchex will provide its contextual advertising solutions to selected areas of the publishers' Web sites, or to channels associated with the sites, such as targeted newsletters and blogs. Marchex's site-specific contextual advertising solutions enable 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 seven new publishers add to Marchex's relationships with more than 100 vertically focused and brand-name online publishers, such as BusinessWeek Online, The Motley Fool, and the Ziff Davis online properties; as well as a large base of premier advertisers.

"As the company that created the site-specific approach to contextual advertising more than five years ago, we are very pleased to build upon our leadership position by adding seven high quality online publishers to our platform since the beginning of the year," said Erik Matlick, IndustryBrains CEO. "As 2007 progresses, we look forward to further increasing our market share while helping all of our new partners more fully realize the value of their online brands, and providing advertisers with direct access to many additional highly targeted audiences."
