Thanks again, Andy:

I would start looking at:

Google - Landing page - Keywords for those pages

that was the first thing I looked at... or should I say, TRIED to look at.

Unfortunately, up to 505 of the keywords are obscured because google has hidden the referring keyword 9since apparently the visitor was signed into their google account and were thus using the https server).

Well, back to the drawing board.
