Web Metrics

Average Daily Unique Browsers (Ave Daily UB):
The average of the Unique Browsers per day in the reporting month.

Unique Browsers (UB):

Each web browser (or device) visiting an audited site is assigned a unique cookie ID to help determine browser uniqueness. This metric displays the number of Unique Browsers which visited a site within the selected reporting period. The Unique Browser metric is scaled to account for users who have cookies disabled.

Page Impressions (PI):

The total number of web pages viewed within the selected reporting period.

Total Sessions:

The total number of times UBs return to a site, having left for more than 30 minutes, during the reporting period. This is calculated by multiplying UB Frequency by Unique Browsers.

Total Time on site (TT ('000 secs):

The total amount of time, reported in thousands of seconds, of all UBs spent on site in the reporting period. This is calculated by multiplying Page Impressions (PI) by Average Page Duration (APD).

Unique Browser Frequency (UB Frequency):

The frequency metric represents the average number of times a Unique Browser returns to a site during the reporting period. This is calculated by dividing the number of UB sessions by total UBs.

Average Page Duration (APD):

The average time pages were viewed on the browser screen for a selected period. This metric is calculated by dividing the total duration of Page Impressions that are less than 30 minutes by the number of Page Impressions. Note: If a page impression lasts 30 minutes or greater it is assumed that the page is no longer being viewed. This is removed from the total duration as it may distort the data.

Average User Session Duration (ASD):

A User Session reflects a period of user activity on a website, provided there is not more than 30 minutesâ€™ inactivity between consecutive events for the same user. This report shows the average length of a User Session. This is calculated by dividing the total of the Page Durations by the total number of User Sessions.

Digital Edition Metrics

Unique Viewers:: The number of Unique Viewers (based on unique cookies) viewing a Digital Edition during the period.
Average Unique Requests:: The average Unique Browsers requesting a PDF file in the reporting period.

Email Newsletter Metrics

Average Net Distribution:: The average number of unique email addresses that have successfully received the email in the period (minus bounces and unsuccessful sends).
