With more than 2 million participants under continuous
measurement, the comScore Global Network is the largest
consumer panel of its kind, and delivers the most comprehensive
view available of consumer activity – both online
comScore has developed a statistical methodology to ensure
the accuracy and reliability of projections to the total
population based on its network. Ultimately this provides
comScore clients with confidence in the quality of information
that drives important business decisions every day.
At the heart of the comScore Global Network is a sample
of consumers enlisted via Random Digit Dial (RDD) recruitment
- the methodology long endorsed by many market and media
researchers. comScore also employs a variety of online recruitment programs, which have been
time-tested through the years in which the comScore Global
Network has been in operation.
The reliance upon comScore services by hundreds of clients
stands as testament to the strength and reliability of
this combined approach.
Participants in the comScore Global Network receive a package of benefits
that have proven to be broadly appealing to all demographic segments:
- Server-based virus protection
- Attractive sweepstakes prizes
- Opportunity to impact and improve the Internet
Participants are protected by industry-leading
privacy policies that ensure anonymity of personal information. Membership
is provided through an efficient sign-up
All demographic segments of the online population are
represented in the comScore Global Network, with large
samples of participants in each segment. For example,
our network includes hundreds of thousands of high-income
Internet users - one of the most desirable and influential
groups to measure, yet also one of the most difficult
comScore determines the size and characteristics of
the total online population via a continuous survey
spanning tens of thousands of persons over the course of
a year. The sample of participants in this enumeration
survey is selected via RDD methodology. Respondents
are asked a variety of questions about their Internet
use, as well as descriptive information about themselves
and their households. The result is an accurate and
up-to-date picture of the universe to which the comScore
sample is projected.
The resulting combination of large samples across all
segments, and a reliable view of the total universe,
allows comScore to eliminate the effects of over- or
under-representation of any group in the network.
comScore services are based either on the
complete Global Network database or from components relevant to client needs. For example,
comScore's industry-leading, RDD-based Media Metrix 2.0 audience measurement system is
founded upon 120,000 U.S. panelists. Media Metrix Global Services are produced using the
behavior of 500,000 panelists outside of the U.S. And Media Metrix XPC (eXPanded Coverage)
adds visibility of smaller Web sites and local market activity through data captured from
the balance of the comScore panel.
comScore's Statistical Services team is comprised of
industry experts with decades of experience in the unique
science of continuously projecting sample-based data
for consumer research.
