So what is Cross-Visit Participation?  In Omniture-speak, it is a JavaScript plug-in that concatenates a series of values into an eVar for attribution purposes.  As alluded to above, the most common use of this plug-in is for what we call Campaign Stacking.  For example, let’s say that a visitor comes to your site from a CNN Display Ad and the tracking code is “cnn_123″ and the same visitor comes the next day from a Google Paid Search keyword with the tracking code “ggl_456″ and then applies for a credit card.  In this case, if you were using the Campaign Conversion Variable (eVar) and the allocation was set to “Most Recent” then the credit card application success event would be attributed to the Google keyword.  However, that visitor may never have conducted a search on Google had he/she not seen the display advertisement on CNN so we may inadvertently reduce the budget for CNN and increase it for Google only to be surprised later that we are not getting as many credit card applications as before.  Sometimes a little (incorrect) data is worse than no data at all!
