Glad they're converting, and I can reverse engineer the paths to some degree, but it's still frustrating not to know what's working, so I can DO MORE OF IT.
How about this:
If the Google referrer is (not provided), display a message on the site that says something like:
Enter the keyword query you used at a search engine to find us and receive an additional 5 percent off your order today.
If the query is not provided, give the users an incentive to tell you what query they used to find the site.
