August 27th, 2007 by Lars
Stone Temple Consulting has done head-to-head comparisons of different web analytics solutions and documented the differences in visitor, unique visitor and page view counts.
Raw unique visitor data
Web Sites
AMD = AdvancedMD
CTI = City Town Info
HP = Home Portfolio
TPD = Tool Parts Direct
Max Differential Per Site - Unique Visitors
Some of the factors that may influence counts:
- Where the JavaScript code is pasted on the page
- Cookie blocking
