Metrics Frequently Asked Questions
Adobe SiteCatalyst is the primary source for the Web Metrics data. The data on Customer Satisfaction is derived from online surveys conducted on CDC.gov, a service provided by Foresee Results.
The Page View metric is defined as the number of times a page has been loaded into a browser (including reloads).
A visit occurs when a single visitor comes to and navigates around the web site. A visit may consist of multiple page views or a single page view. A visit is also called a “session.” The visit/session persists until 30 minutes of inactivity or 12 hours of continuous activity. After this, it’s considered a new visit/session and new visitor.
For example, each time a search is conducted for a particular keyword, the number of instances associated with that keyword increases by one. The instance metric is displayed in the Referrers, Referring Domains, and most Conversion Reports.
A clickthrough refers to the number of times a user clicked on a link, button, badge, or graphical image that is linked to another page. When a user clicks on the link and arrives on a landing page, this counts as one clickthrough.
No, at this time, CDC does not track unique visitors or repeat visitors in our web metrics collection. Persistent Cookies have been disabled, therefore we are only able to track visits and page views.
