SEATTLE, WA and NEW YORK, NY - April 25, 2007

Marchex, Inc. (NASDAQ: MCHX, MCHXP), in conjunction with its IndustryBrains subsidiary, today announced that it has signed contextual advertising agreements with four online publishers, including Computer Shopper, Engineering.com, Wall Street Reporter, and SitePoint. 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.

"IndustryBrains has been a leader in delivering targeted advertising to publishers in the technology category for many years," said Josh London, General Manager, Online for Computer Shopper. "We are looking forward to our partnership with IndustryBrains, so that we can present ComputerShopper.com users to the most relevant advertisers at industry leading cost-per-click rates."

"Adding these quality vertical publishers further reinforces our position as the leader in site- specific contextual advertising," said Peter Christothoulou, Marchex Chief Strategy Officer. "The combination of the depth of our quality publishers and targeting capabilities provides advertisers with excellent tools to maximize their performance."

Marchex's IndustryBrains subsidiary pioneered the site-specific approach to contextual advertising more than five years ago, with the 2002 launch of its contextual advertising platform. This approach allows brand-name publishers to directly benefit from the value of their respective online brands, content and site traffic. The new publishers announced today add to Marchex's 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.
