Comscore Introduces Significant Enhancements to Search Measurement with Comscore qSearch 2.0

RESTON, Va., August 20, 2007 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced the launch of Comscore qSearch 2.0, the second generation of search measurement. Previously, the search universe was defined as searches occurring at the major Web search engines. With search becoming a more ubiquitous activity across the Web, Comscore is expanding the market view of the search universe to encompass other searches that occur on the Internet.

Comscore’s qSearch 2.0 interface will provide clients with an in-depth view of the search universe in the U.S. and worldwide that encompasses:

• Core Search Engines – the five major U.S. search engines (i.e. Google Sites, Yahoo! Sites, Microsoft Sites, Ask Network and Time Warner Network).
• Top 50 properties worldwide where search activity is observed, which includes sites such as MySpace, Baidu, and Naver.
• Major “vertical” search locations - such as eBay and Amazon in retail and Expedia in travel.
• Partner Search – searches initiated at partner sites that redirect the visitor to a search engine site.
• Cross-Channel Search – counts multiple searches when employing more than one search tab (e.g. Web, images, news) for a single search term.
• Local Search – maps, directions, and local directory listings.
• Worldwide Search – includes comprehensive reporting of worldwide search, with individual country reporting for the U.S., Canada, Mexico, U.K., France, Germany, Japan, China, and Korea. Additional countries will follow.

“With the continued evolution of the search market, it has become clear there is a need to expand the way we think about search,” said James Lamberti, Comscore senior vice president of search solutions. “qSearch 2.0 gives the most comprehensive and accurate view of the entire search market by including all forms of search that are being monetized currently or could be monetized in the future.”

The Comscore qSearch 2.0 service will now provide clients with the ability to discern whether the search originates from a text box on a search engine portal, an auto-search typed in the browser’s URL line, a search from a text box on a downloaded search toolbar, local search, or a partner site. The expanded search universe will progressively add the ability to view search within a collection of vertical sites such as shopping, travel, or careers.

July U.S. Core Search Rankings

Comscore will continue to publicly report a market share ranking for search engines known as “core search.” These market share data will use a definition comparable to Comscore’s previous public search share reporting. As before, share will be determined using the five major search engines (Google Sites, Yahoo! Sites, Microsoft Sites, Ask Network and Time Warner Network) but will now include the partner searches and cross-channel searches in the total for each property. To keep this metric consistent with past reporting, searches for mapping, local directory, and user-generated video sites that are not on the core domain of the five search engines will not be included in the “core search” numbers.

In July, Google Sites ranked as the top core search engine with 55.2 percent share of searches among the top five engines. Yahoo! Sites ranked second with 23.5 percent, followed by Microsoft Sites (12.3 percent), Ask Network (4.7 percent) and Time Warner Network (4.4 percent).

Google Sites led the market with nearly 5.5 billion search queries in July, up 2.4 percent versus June and 64 percent versus year ago, followed by Yahoo! Sites (up 0.8 percent to 2.3 billion searches), Microsoft Sites (up 2.8 percent to 1.2 billion), Ask Network (up 2.9 percent to 462 million), and Time Warner Network (down 0.9 percent to 436 million). Google benefits disproportionately from affiliate searches and multi-tab searches that help raise its share of core searches relative to the share reported in qSearch 1.0.

July U.S. Expanded Search Rankings

Comscore will also publicly report the number of search queries conducted in the expanded search universe for the top 10 search properties. In July, Google Sites ranked as the top property in the expanded search universe with 6.6 billion searches, driven by Google (5.5 billion) and YouTube/All Other (1.1 billion). Yahoo! Sites ranked second with 2.5 billion, followed by Microsoft Sites (1.3 billion), Time Warner Network (959 million), and Fox Interactive Media (587 million).

“Comscore is leading the way in measuring a search landscape heavily affected by Web 2.0,” commented Dr. Magid Abraham, CEO and co-founder of Comscore. “qSearch 2.0 adapts to the blurring of ‘classic search’ and enables clients and research analysts to evaluate the newly emerging players and the new types of searches that can potentially have significant monetization opportunities. This is an excellent example of Comscore innovating to respond to the challenges of a fast moving marketplace”.
