Webtrends Analytics 9.2
Cause
Google uses GCLID to indicate a paid search. Beginning February 2009, Webtrends made a change to the Webtrends JavaScript tag created in Webtrends Tag Builder that allows WT.srch=1 to automatically populate if GCLID is passed in the referrer.
Resolution
If GCLID is not populated, WT.srch=1 must be manually added to the link users click on from the search engine to capture paid search traffic.
