Cookie Lifespan report


Level 4


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?



Level 4


Absolutely second this one.

This is something that we've been looking at doing from a code standpoint, using a counter evar or something like that...but as SiteCatalyst has the data already, why not expose age of cookie as a report?


I think as marketers we are conscious of cookie-deletion...but is it really something we need to worry about?  We don't know as we can't see the data.  So this would be a very insightful report.




Level 1


I also think that this would be a very insightful report too. Specially for mobile sites... certain phones block 3rd party cookie by default making the number of UB's inflate...


Whilst I can track through a prop/ eVar who accepts cookies and who doesn't I don't get the age of the cookie and I have to manually implement that....


It would be much easier if Omniture can provide this information since you guys are already collecting it


Thank you,
