News Release Details

SEATTLE, WA - December 13, 2004

Marchex, Inc. (NASDAQ: MCHX), a provider of technology-based merchant services that facilitate and drive growth in online transactions, today announced agreements with two of the Internet's leading product shopping services, through its TrafficLeader subsidiary, designed to provide expanded marketing and distribution opportunities for its merchant advertisers. The agreements are in addition to a series of similar arrangements Marchex announced with other participants in the online product shopping sector earlier this year.

Under separate shopping agreements with PriceGrabber (www.pricegrabber.com), a leader in comparison shopping, and Google's shopping search engine, Froogle (http://froogle.google.com), TrafficLeader's merchant advertisers will have their products and services delivered in search results through each shopping partner, based on the relevance of their offerings to users' search queries, using managed search feeds provided by TrafficLeader. As part of the agreements, TrafficLeader will also deliver images relevant to the merchants' products and services within the search results.

These agreements further augment Marchex's strategy to build out a specific product shopping distribution channel for its merchant advertisers, in addition to the existing search feed management services that are delivered into broader search and directory services. Combined with relationships already in place with Yahoo! Shopping (http://shopping.yahoo.com/), Shopping.com (www.shopping.com), CNET's mySimon (www.mysimon.com) and NexTag (www.nextag.com), Marchex now has agreements in place with what are widely recognized as six of the Internet's leading product shopping providers.

"We are very pleased to make these additions to our product shopping distribution channel, enabling our merchant advertisers to deliver their product information to a larger base of consumers," said Peter Christothoulou, Marchex Chief Strategy Officer. "At the same time, as we bring more merchants into this offering, it is increasingly compelling for shopping engines to work with us to gain access to more high-quality products."
