News Release Details

SEATTLE, WA - (October 29, 2008) -

Marchex, Inc. (NASDAQ: MCHX), a local search and advertising company, today announced that its Marchex Adhere for Publishers has added 23 new premium Web sites, bringing its roster to more than 200 premium publishers using Marchex Adhere to more effectively monetize their Web sites. The new Web sites include Inc.com, UPI.com, WirelessWeek.com, and NationalReview.com. In addition, Marchex renewed its agreements with The Motley Fool and The Globe and Mail, Canada's number one newspaper Web site.

Marchex Adhere for Publishers is a private label advertising platform that provides premium publishers with their own branded performance-based advertising marketplace. Unlike traditional ad networks, Marchex Adhere gives publishers greater control over their own inventory, which they can sell directly, have Marchex sell, or a combination where both parties deliver advertisers into the marketplace. In all cases, publishers can set the minimum price for their inventory, decide which advertisers appear on their sites, determine the look and feel of the advertising units, and be supported by their own reporting center.

"We've spoken with scores of publishers and they all tell us they want more control over advertisers, pricing, quality, and results," said Scott Greenberg, Senior Vice President of Advertising Services at Marchex. "With most outsourced advertising providers, the publisher is at the mercy of the ad network and as a result, almost any kind of ad can show up on their sites and their ability to maximize the value of their inventory is diminished, especially for a premium publisher who can typically command very high rates. Marchex Adhere is the 'anti-network' providing premium publishers the control they want over their inventory and advertiser relationships; and advertisers the ability to advertise on specific premium Web sites versus a blind network."

The Marchex Adhere platform serves the most relevant text ads to maximize each site's revenue while maintaining its editorial integrity using a ranking system based on relevance, performance, and price-per-click.

Marchex Adhere for Advertisers provides advertisers with the opportunity to target their advertisements to a specific Web site, a specific Web page within a site, or to a category (i.e. Finance). This gives advertisers a high level of transparency knowing where their ads will appear and the ability to measure their return on investment, in addition to direct access to top premium publishers in key verticals.

"We've had a successful track record employing the Marchex Adhere platform for our sites over the past several years," said Martha Connors, Vice President/Group GM, IDG. "Marchex Adhere for Publishers provides us with the control we need to maximize the value of our pay-per-click inventory across our category leading properties including CIO.com, Computerworld.com and Infoworld.com."

Marchex Adhere for Publishers includes more than 200 premium publishers, including leading business and finance sites such as BusinessWeek.com, Kiplinger.com, Bankrate.com and Investors.com; leading IT sites such as IDG's PCWorld.com and NetworkWorld.com or Ziff Davis Enterprise's eWeek.com and CIOInsight.com; and top real estate sites such as HomesandLand.com and RealtyTrac.com.
