JICWEBS (the Joint Industry Committee for Web Standards) was created by the UK and Ireland media industry to insure independence and comparability of measurement on the web. In effect JICWEBS works in partnership with the ABCe, with JICWEBS deciding whether metrics are desirable and ABCe deciding whether they are practical.
Web Metrics are intended to measure activity on web sites in a site centric fashion. These can include measurements of audience reach, frequency, and activity levels including the use and effectiveness of advertising on the web and other electronic media.
