Definitions
Unique Users
One unique user is counted for every distinct 'cookie' which has visited a website within a given timeframe (in this instance, a week). A cookie is a small piece of information that a server sends to a user's computer to identify that computer on its return.
Live listening hours
One live listening hour is counted for every hour of live BBC radio streamed online
Downloads
One download is counted for every downloadable file successfully transferred to a user's computer
How the stats are collected and audited
In all cases, only requests that originated external to the BBC are counted. We count no internal traffic.
Page Requests and Unique Users
Page request and unique user data is taken from the BBC web server logs. The data is cleaned to give only those requests that are related to legitimate page requests as defined by ABCe. We then count the number of requests seen for each particular item of content (such as a radio website), and also the number of unique cookies associated with those requests. Each cookie count is de-duplicated (i.e. each cookie is only counted once towards any given piece of content in any given time span).
Play durations for live audio
The live duration data is taken from the BBC media serving logs. We count the duration of the content that was listened to. These figures are then aggregated for each area of content (such as a particular radio show or station).
Auditing
The BBC's website figures are audited twice a year (typically March and September) by ABCe.
