News Release Details

SEATTLE, WA, June 4, 2007 -

Marchex, Inc. (Nasdaq: MCHX) today announced a new relationship with Yahoo! Inc. in which Marchex will convert search ad listings from its pay- per-click engine, Enhance Interactive, into Yahoo! Sponsored Search listings.

Yahoo!, a leading global Internet brand, launched its new search marketing system, known as Panama, in the fourth quarter of 2006, providing advertisers with new capabilities including geo-targeting. Marchex will utilize the geo-targeting capability made available through Yahoo!'s search marketing application programming interface (API) to provide its Enhance Interactive advertisers with more targeted campaigns based on each advertiser's target markets.

"It is an ongoing initiative for us to offer additional quality distribution to our direct pay- per-click advertisers, and this is a continued step in that process," said Scott Greenberg, Marchex senior vice president of advertising services. "This partnership will enable us to expand the reach of our advertisers in the United States and beyond."

This relationship should provide advertisers using Marchex's pay-per-click engine, Enhance Interactive, with a new source of quality traffic and broader global reach. It is another step in Marchex's ongoing initiative to provide its advertisers with additional premium traffic and the tools needed to both extend their search marketing campaigns and maximize their return-on-investment (ROI) from search marketing.

More information for advertisers is available at www.enhance.com. Enhance Interactive customers can also contact their current account manager for more information or contact Customer Support at the following email address: cs@enhance.com.
