The website search analysis tool Google Webmaster introduced page level query data which makes the system more similar to Google's Analytics program. The new tool provides information about which search queries drive traffic to which pages of your website. A new Top pages area reveals the top performers in Google's search engine. Included in the data are impressions, click counts, and average position.
Simply stated, this new functionality will help reveal which keyword search terms drive the most traffic to your website and which specific pages receive that traffic.
