New Comscore Segment Metrix Enables Powerful Segmentation of Online Audiences

LONDON, UK, SEPTEMBER 25, 2007 – Comscore (NASDAQ: SCOR), a leader in measuring the digital world, today announced the launch in France of its ground-breaking Comscore Segment Metrix analytical tool.

Comscore Segment Metrix enables clients to conduct insightful segmentation analyses of the extensive Comscore MMX online behavior database using a wide variety of consumer segmentation schemes. The product provides the flexibility to integrate three different types of segmentation schemes with the MMX data — segments based on the observed online behavior, proprietary segmentation schemes clients currently use, and segmentation approaches from third party analytical consultants.

The key benefits of Comscore Segment Metrix include:

• Media owners are able to determine if they are getting their fair share of heavy users compared to other properties in their sector
• Agencies and advertisers can attain better insight into how to reach important target customers
• Advertisers can now integrate their offline marketing segmentation schemes with Comscore’s online panel, allowing them to track, analyze and report online behavior by these important (offline) consumer segments

“Consumer segmentation is not new - it is an important part of marketing, and over the years Comscore has conducted a great deal of custom segmentation work,” said Bob Ivins, EVP of International Markets at Comscore. “With Comscore Segment Metrix, marketers can define consumers behaviorally and then identify where to find them across the web — making media and promotion plans more targeted, efficient and effective.”
Heavy Internet Users Visit More Sites and Consume a Disproportionate Share of Pages

The first segmentation to be offered is one defined by online behavior. This approach, called Comscore Segment Metrix H/M/L, allows marketers to analyze online activity by heavy, medium and light users of the Internet and by any specific categories of sites reported by Comscore. The Heavy segment group will be defined as the top 20 percent of consumers, based on time spent online at specific site categories; the Medium group will be defined as the middle 30 percent; and the Light users are the lightest 50 percent. H/M/L user segments will be available in all 32 countries where Comscore syndicated data is available and across all 110 Comscore defined categories and sub-categories of sites.

* Users age 15+. Excludes traffic from public computers such as Internet cafes or access from mobile phones or PDAs
The average French Internet user spent 25.0 hours online in July and made 60.1 site visits. However, when we break this population down to reveal the consumption habits of heavy, medium and light users, we can see that there are significant differentials between the segments. Heavy Internet users spent almost three times more time online in July – 73.3 hours – and made more than twice as many site visits as the national average.
“By definition, heavy Internet users consume a disproportionately high share of content. The H/M/L segmentation gives our clients the ability to understand the behavior of one segment versus the others and to determine if they are getting their fair share of heavy, medium or even light Internet or category-specific users,” commented Mr. Ivins. “There are also stark and important differences across these groups, which represent critical knowledge for advertisers with specific reach and frequency objectives.”

Comscore Segment Metrix can provide further insight into the online behavioral differences between the segments. For instance, we see substantial differences in the types of sites that heavy internet users visit compared to those the light users visit. Light users are more likely to be found using finance, reference, and travel sites, whilst heavy users spend an above average proportion of their time on conversational media, gaming, and entertainment categories. This insight would be useful to a media planner who is trying to efficiently extend the reach of a media plan. By advertising on the sites that appeal to light internet users, they can more efficiently build reach than by buying ads on sites that would build frequency among heavier users.
