How to calculate year-to-date unique visitors with report builder?
Using Omniture + Report Builder (Excel) , I'm trying to calculate year-to-date unique visitors on a weekly basis. Right now, this is a manual process:
The "Year" start date is September 30. So to find out YTD unique visitors for each day last week, I calculate unique visitors for September 30 - December 9...then September 30 - December 10...then September 30 - December 11, etc. etc.
We realize this isn't an ideal way to get this metric, but it's what the client wants. Anyone have a suggestion for a formula in order to automate this through Report Builder?
