3. Basic Problem: No Unique User ID
Web Analytics Approximation
Unique User = Cookie ID (if Cookies can be set) or
IP Address + User Agent
More Problems!
• Cookies are deleted, and when they are, the same user can be counted
multiple times
• IP Addresses change all the time causing inflation of user counts
• In any case, a UU is an attempt to identify a machine (or a browser),
which can represent multiple people or a fraction of the usage of a single
person
