Marchex Launches Beta for Nationwide Portfolio of Local ZIP Code-Based Web Sites

SEATTLE, WA - August 8, 2005

Marchex, Inc. (NASDAQ: MCHX, MCHXP), today introduced a beta interface for 52 local ZIP Code-based Web properties it owns, developed to provide local search, locally- targeted advertising inventory, and geographically-relevant content for ZIP Codes within each of the nation's 50 most populous metropolitan areas (source: Nielsen Media). During the next several months, Marchex plans to extend localized versions of the new interface across its portfolio of more than 73,000 ZIP Code-based Web properties nationwide.

Additionally, Marchex is providing information on its overall portfolio of more than 200,000 direct navigation Web properties, including recent progress within its vertically- and locally-focused Web properties.

ZIP Code Beta Launch:
Marchex developed an initial user interface for its local ZIP Code Web sites to offer a useful experience for online users who search locally, while providing opportunities for placement of geo-targeted advertising inventory to advertisers who are interested in offering their products and services in specific local markets.

The following is a list of sample beta ZIP Code implementations:

New York area:
Los Angeles area:
San Francisco area:
Boston area:
Seattle area:

Marchex's beta launch of its ZIP Code user interface includes elements that allow Marchex to: (i) dynamically apply distinct user interfaces to a single Web site or multiple Web sites within a given vertical category; (ii) incorporate multiple data feeds (e.g., local weather, local mapping, local demographic data) onto a given Web site or a category of Web sites; and (iii) incorporate advertising opportunities (e.g. locally-targeted text listings, product shopping listings, yellow-page listings, classifieds).

Marchex developed its localized ZIP Code interface to be highly complementary to the company's existing assets and partnerships. For example, the yellow pages portion of Marchex's ZIP Code interface is powered by the company's recently acquired assets from Pike Street Industries, which in turn drives traffic to Marchex's regional bell operating company (RBOC) partners. This traffic is then dynamically routed by the RBOCs through their directories to the appropriate local merchants. Marchex also plans to place targeted text advertising listings from its advertiser network and search properties.

"We are focused on building a leadership position in direct navigation, where we see substantial opportunities in providing higher levels of user utility while monetizing this diverse portfolio of Web sites," said John Keister, Marchex President and COO. "Our portfolio of Web properties provides highly-targeted advertising and distribution opportunities for our clients and strategic partners in many key vertical segments."

Marchex's portfolio of local ZIP Code Web properties includes the following:

  • Marchex consolidated ZIP Code coverage: Marchex's owns more than 73,000 .com and .net ZIP Codes, which reflects an estimated 96% coverage of all U.S. ZIP Code areas - meaning that Marchex owns a .com and/or a .net ZIP Code in approximately 41,000 of the approximately 42,500 U.S. ZIP Codes (source: U.S. Postal Service). On this basis, Marchex estimates that its .com and .net ZIP Codes cover geographical areas comprising approximately 94% of the 281 million U.S. Population and 94% of the 111 million U.S. residences (source: 2000 U.S. Census).
  • Marchex ZIP Codes with a .com Top Level Domain (TLD): Marchex owns more than 33,000 .com ZIP Codes, which it estimates reflects 78% coverage of the approximately 42,500 U.S. ZIP Codes available.
  • Marchex ZIP Codes with a .net TLD: Marchex owns approximately 41,000 .net ZIP Codes, which it estimates reflects 96% coverage of the approximately 42,500 U.S. ZIP Codes available.

Marchex's Vertical and Local Categorization of Direct Navigation Properties:
In addressing its overall portfolio of vertical and local Web sites, Marchex is announcing today the categorization of its more than 200,000 domains.
