Example: An estimated 4.1 billion search queries were conducted at Google Search, representing 56 percent of all search queries conducted during the given time period.

Note: Effective with October 2007 reporting, Nielsen Online has made several enhancements to its MegaPanel service. These enhancements include more granular reporting, increased accuracy, an expanded Internet universe and more advanced tracking.

Because of these methodology changes, previous results from MegaPanel-based products, including MegaView Search and MegaView Online Retail, cannot be trended with current results. While we regret that trending data is not presently available, we believe these product enhancements will provide the highest quality data possible to our clients and the marketplace.
