AltaVista Unveils Streamlined Look-and-Feel with New Logo and Exciting New Programs for Advertisers

Phases Out Pop-Up, Pop-Under and Skyscraper Advertising in Favor of More Targeted Ads to Better Address Advertisers' and Users' Special Interests

PALO ALTO, Calif.,November 12, 2002 - AltaVista Company, a leading global provider of search services and a majority-owned operating company of CMGI, Inc. (Nasdaq: CMGI),today unveiled a new streamlined user interface complete with a new logo and several exciting new advertising programs designed to maximize appeal to both advertisers and search users. In August of this year, AltaVista became one of the first online properties to phase out pop-up ads, and the company is structuring new advertising programs to maximize the matching of advertiser ads with users' search interests. Today's announcement is made concurrently with the company's announcement of new features and functionalities designed to advance the overall user search experience (see separate press release, "AltaVistaŽ Advances Internet Search with New Features and Functionality for 'Power of Precision' Searching").

Search engines empower consumers and business buyers to research products and services, and to evaluate alternatives. According to a 2001 report from Jupiter Research, the research of products and services accounted for 78% of Internet usage in 2001. 1

"We've streamlined the look-and-feel of our site and redesigned our logo to reflect our reenergized focus on our core strength -- Internet search. We think users will appreciate the new look as well as all the new features of our 'Power of Precision' initiative," said Jim Barnett, Chief Executive Officer for AltaVista. "In addition, because the online buying process today almost always starts with a search, we are offering a range of new targeted advertising programs we believe will appeal to a wide array of advertisers."

Eliminates Pop Up and Skyscraper Ads, Extends Paid Listings
AltaVista eliminated Pop-up and pop-under ads on its U.S. site in August of this year, and will continue to phase them out from its other country sites over the next several months. The company has also phased out the 'skyscraper' ads that were located on the right-hand margin of the search results pages, replacing them with additional paid listings.

"We've added several exciting new advertising opportunities aimed at making AltaVista the most advertiser-friendly search site to do business with, while at the same time retaining complete respect for the user experience," said Jeff Lehman, Chief Revenue Officer for AltaVista Company. "Additionally, we believe that the more focused advertising becomes, the less intrusive and more effective it is in a search environment. Search users consider the combination of highly targeted advertising along with precise search results to be a more complete search experience and more beneficial to their overall needs. This is the core of special interest marketing and our wide range of ad programs surrounding search are what make us unique in the search advertising community."

New Advertising Programs
In response to changes in the online advertising market, AltaVista has created a number of new advertising programs to help advertisers better target their audiences and deliver the appropriate information to users in search of product and retail resources.

New Products

AltaVista's new home page promotional units give advertisers a high profile branding and traffic-driving opportunity with prominent AltaVista 'front page' exposure, ideal for new product introductions and special promotions. The new Integrated Search Units, which are keyword-targeted, offer advertisers and users specialized search functionality related to specific interests. The Marketplace ISU listings and FSUs also give advertisers prominent homepage exposure within the Marketplace section for another high profile traffic-driving opportunity. Tracer ads, which are currently being test marketed, extend the value and exposure of a keyword even if it is already 100% sold, by linking ads directly to users' additional searches.

Multimedia Extend Your Search (EYS) is ideal for advertisers with a strong offering relevant to a media category (images, audio, video). With targeted results on the advertiser's site, these can be targeted to one or all media categories. For example, a user query about 'cars' can direct the person to sites with image collections of automobiles or video clips of important races.
