I don't doubt that.

First thing they'd need to do is determine who (or what) is doing the searching.

Next they'd need to *guess* at the purpose for the search.

Without those 2 things happening first, I can't see where their *behavior* tells them much of anything especially as related to the ordering of the results.

"Armies" of searchers, alive or automated, clicking on results, following some and bouncing on others. Hmmmm... Click fraud round 2.
