Abstract:

ABC Interactive (ABCi), with cooperation of the Interactive Advertising Bureau (IAB) and the Media Rating Council (MRC), performed an analysis of different methods of measuring unique visitors for a sample of websites. The analysis demonstrates the large differences that can be obtained using different methodologies, as well as providing insight into the nuances of log-based measurement. The paper concludes with recommendations for accurate visitor counts.
