Abstract:

During 2001, CESP conducted an audit of the three Internet audience panels currently serving the French market, focusing as much on their enumeration surveys as on the panels themselves. This paper presents the various stages of the audits and the methodological issues involved in each phase as well as highlights certain elements often underestimated and yet with an influence of great importance on the quality of results. The current situation of the rival operators is presented, as well as the prospects for their new service offerings, as far as it is possible to know this given the highly uncertain current environment and giving equal attention to the French and international markets.
