Traffic Profile Metrics

The Traffic profile contains the following metrics to identify visitor traffic.
Metric Metric Formula and Level Description
Entries Formula: Page_Views[no shift(None,Page_View, Session,-1)]
Level: Page View
The number of sessions that entered the site on each page. This metric is evaluated over the Page dimension only.
Exit Rate Formula: Exits/Page_Views
Level: Page View
The percentage of sessions that exited the site from each page. The Exit Rate metric can only be evaluated over the page dimension.
Exits Formula: Page_Views[no shift(None,Page_View, Session,1)]
Level: Page View
The number of sessions that exited the site from each page. This metric is evaluated over the Page dimension only.
LVCI90 Formula: (raw(Visitors) - ((raw(Visitors) + .69)^0.5 * 1.281551 - 1.2269))*(Visitors/raw(Visitors))
Level: Visitor
A measure of the lowest number of possible visitors as reported by Insight. Mathematically, it specifies the lowest number of visitors with a 90% probability.
Page View Duration
Formula: sum (exact_page_duration, page_view)*0.1/Page_Views[any Exact_Page_Duration]
Level: Page View
The average length of time (MM:SS) spent on a particular page or group of pages. This metric is evaluated over the Page dimension only.
Page Views per Session
Formula: Page_Views/ (Sessions by Page_View)
Level: Session
The average number of page views in each session that has page views.
Page Views Formula: sum(One, Page_View)
Level: Page View
The number of page views. A page view is a request for a defined page (access to images and other types of filtered content are not counted).
Pct of Page Views Formula: Page_Views/total(Page_Views)
Level: Page View
The percentage of page views.
Pct of Sessions Formula: Sessions/total(Sessions)
Level: Session
The percentage of sessions.
Pct of Visitors Formula: Visitors/total(Visitors)
Level: Visitor
The percentage of visitors.
Pct Referred Visitors
Formula: Referred_Visitors/Visitors
Level: Visitor
The percentage of visitors that were referred to this site from another site.
Referred Sessions
Formula: Sessions[Referrer<> 'None' and Referrer<>'bookmarks']
Level: Session
The number of sessions that were referred to this site from another site.
Referred Visitors
Formula: Visitors[Visitor_ Referrer<>'None' and Visitor_Referrer<>'book marks']
Level: Visitor
The number of visitors that were referred to this site from another site.
Retention
Formula: Sessions[shift(None,Ses sion,Visitor,1) = ""] / Sessions
Level: Session
The percentage of sessions that are not the visitors last sessions.
Session Duration
Formula: (sum (Exact_Page_Duration, Session)*.1/Sessions)[Session_ Duration <= '01:00:00']
Level: Session
The average length of time (MM:SS) a visitor spends in a session.
Note: You can use this metric with the Segment Export feature.
Sessions by Page View
Formula: Sessions by Page_View
Level: Session
The number of sessions that had a page view.
Sessions
Formula: sum(One, Session)
Level: Session
A count of visitor sessions. A session is a period of activity for one visitor of a web site. Individual sessions for each visitor are identified using cookies, timeouts, and other heuristics.
SCI80
Formula: confidence(Sessions) * 1.281551 / Sessions
Level: Visitor
A measure of confidence of the Sessions metric as reported by data workbench. Mathematically, it is a +/- percentage specifying the range within which the actual answer will lie 80% of the time. As a rule-of-thumb, doubling the SCI80 percentage will give a range within which the actual answer will lie 99% of the time.
UVCI90
Formula: (((raw(Visitors) + .68)^0.5 * 1.281551 + 1.2269) + raw(Visitors))*( Visitors/raw(Visitors))
Level: Visitor
A measure of the highest number of possible visitors as reported by Insight. Mathematically, it specifies the highest number of visitors with a 90% probability.
VCI80 Formula: ((raw(Visitors) + .68)^0.5 * 1.281551 + 1.2269) / raw(Visitors)
Level: Visitor
A measure of confidence of the Visitors metric as reported by Insight. Mathematically, it is a +/- percentage specifying the range within which the actual answer will lie 80% of the time. As a rule-of-thumb, doubling the VCI80 percentage will give a range within which the actual answer will lie 99% of the time.
Visitors by Page View
Formula: Visitors by Page_View
Level: Page View
The number of visitors that had a page view.
Visitors by Session
Formula: Visitors by Session
Level: Session
The number of visitors that had a session.
