News Release Details

SEATTLE, WA - November 7, 2006

Marchex, Inc. (NASDAQ: MCHX, MCHXP) today announced the launch of the Marchex Network, an advertising network featuring Marchex's more than 200,000 owned and operated Web sites which attract tens of millions of unique users per month (1). Advertisers can directly bid for placement on a Cost-Per-Click basis across Marchex's network of Web sites, based on designated keywords and categories.

"Our initial campaigns on the Marchex Network have been very successful in terms of conversion rate and return on investment," said Josh Boaz, Director of Business Development, DirectAgents, a New York-based interactive advertising and marketing agency. "With a higher conversion rate than what we have seen in many other channels, the Marchex Network has proven to be effective at acquiring customers for our clients and raising awareness of their products."

"Advertisers continue to seek out premium traffic and targeted search inventory beyond the incumbent top online search engines," said John Keister, Marchex President and COO. "Direct navigation traffic is recognized to be among the highest converting online traffic sources available, and as we continue to build out the content on our Web sites, the Marchex Network will be an even greater source of qualified traffic for advertisers."

According to a 2006 WebSideStory study, direct navigation traffic (when users type a domain or keyword directly into their browser bar or use a bookmark) converts at 4.23% on average, a higher rate than other sources, including search engines at 2.3% (2).

Examples of the targeted domains within the Marchex Network include www.debts.com, www.insuranceinformation.com, www.floral.com, www.videocamera.com and travel related sites, such as www.napavalleywine.com and www.californiadining.com, which feature additional content provided by Open List, Marchex's search technology and content aggregation engine. This content includes product or service descriptions, ratings, expert third-party reviews, user- generated reviews, awards, maps and other information. In the coming months, Open List content will expand beyond the travel vertical and be integrated into additional categories across the Marchex Network.

Advertisers interested in the Marchex Network can contact Marchex Network sales at networksales@marchex.com.
