GfK Media Efficiency Panel
The GfK Media Efficiency Panel displays a worldwide unique measurement of online behaviour and media usage combined with shopping behaviour (online and offline) in a single source panel with a sample size of 15,000 households.
The measurement of internet use is made possible by an installation of a browser extension on the PCs of the panel participants.
