If you are using both Google Analytics and Omniture Site Catalyst then you know that both these tools require different campaign variables to track campaigns. So what are the ways you can satisfy the requirements of both the tools so that you can see campaign performance in both of them.
Option 1 (Best Option): Use multiple query parameters
For GA you should use utm_campaign, utm_source, utm_medium
For Omniture add another parameter say ocid
Option 2: Use one set of variables for one tools and convert them for other tool
campaignvalue = ‘spring : msn : banner’
The set this as the value for s.campaign value in Omniture
s.campaign = campaignvalue;
