The comScore Media Metrix qSearch service measures search-specific traffic on the internet. qSearch data is gathered by monitoring the web activities of 1.5 million English-speakers worldwide (1 million in the United States) via proxy metering. Proxy metering allows comScore to see exactly how those within its panel have surfed the web. From this data, the company then extracts activity that's considered to be specifically search-related.
The Nielsen//NetRatings MegaView Search reporting service measures the search behavior of approximately 500,000 people worldwide. These web surfers have real-time meters on their computers which monitor the sites they visit. This metered information is compiled to produce NetRatings results.
