It would be great if we could have a report which indicated the average age and/or age distribution of SiteCatalyst tracking cookies (current time - cookie creation time) generating visits in a Report Suite over a certain time period.
Why you say?
A lot of reporting in SiteCatalyst is derived from cookie-based data.
There are a lot of ways that the relatioship between cookies issued and a specific human user can be interrupted;
- multiple browsers per user
- multiple devices per user
- multiple users per browser
- blocking of cookies from a browser
- deleting cookies from a browser
I understand that there is no maigc bullet for the effect the above factors have on cookie <-> user, and certainly over time the effect grows in a given cookied population, but I would like to be able to assess the rate of the effect and therefore the confidence I can place in cookie-based reports over a given time period.
eg If I am trying to track attribution of multiple campaigns to conversion, does the average cookie in my user population last long enough to record first and last touch over the campaign period?
