Comscore Announces New Interactive Search Intelligence Service

“Comscore Marketer” Service to Enable Marketers to Benchmark Performance and Optimize Online Marketing ROI

RESTON, VA, October 1, 2007 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today announced the launch of Comscore Marketer, a new interactive search intelligence service that enables search marketers and Web site operators to benchmark their performance versus competitors and optimize the ROI from their search marketing efforts.

“Comscore Marketer is a new service that gives marketers a powerful and comprehensive set of tools to assess their online marketing performance,” said Dan Lackner, senior vice president of Comscore. “The granular information on both searchers and search terms available through this service empowers users with actionable search marketing intelligence.”

Comscore Marketer provides search marketers the tools to:

• Create more efficient and cost-effective campaigns using paid and organic search terms.
• Identify high performing search terms at a site and category level.
• Analyze searchers and the use of search terms by demographic segment.
• Discover high-potential consumer segments and pinpoint the optimal search sites and search terms to reach them.
• Find out who is competing on search terms to identify prime affiliate marketing partners.
• Maximize the ROI of search and online marketing investments.

Comscore Marketer Highlights Paid versus Organic Search Referrals

One of the key benefits of Comscore Marketer is the ability to perform competitive analysis of a market based on organic and paid click-thrus. The analysis below depicts the top click-thru destinations for people searching using the terms “credit card” or “credit cards.”

The results reveal that CreditCards.com is the top click-thru destination for the aforementioned search terms, accounting for 10.6 percent of all click-thrus, followed by JP Morgan Chase Property (8.1 percent) and HSBC (6.1 percent). That CreditCards.com is the top destination is a function of its heavy paid search advertising strategy, as two-thirds (67.0 percent) of clicks to the site result from paid clicks. Meanwhile, JP Morgan Chase Property and HSBC each generated at least 6 percent of total click-thrus on the search terms, but with a significantly lower share of clicks resulting from paid search (22.7 percent and 38.1 percent, respectively). In other words, these sites are relatively more effective than CreditCards.com at generating “credit card”-related clicks via organic search results.

“CreditCards.com is clearly being more aggressive than its competition on the paid search front,” continued Mr. Lackner. “Ultimately, that strategy might pay off, as long as the site is receiving an incrementally higher return on its paid search dollars. In order to optimize the return on their online marketing investment, companies must understand how they’re performing relative to their competition.”
