Traffic Source

WT.tsrc

WT.tsrc=traffic source value(overrides default value)
By default, Webtrends reports on the source of traffic based on its referrer using the following values: "Paid Search," "Non-Search Campaigns," "Organic Search," "Other Referrers," or "Direct".

This information is tracked in the custom Traffic Source dimension. You can use the WT.tsrc parameter to override any of the default Traffic Source values with a custom value.
