Google has automated taxonomy assignments for query types and for URLs. If the taxonomy assignment algorithm can't figure out where your page "fits", they might keep trying different categories for it in an automated, machine learning fashion.
But why is it taking the machine so long to figure this out? Based on what gadget26 is seeing during zombie periods, Google should be able to detect the higher bounce rates and shorter time on site, even if they can't detect how many pages people are vising before leaving. And during the on-time, the machine should notice improved bounce rates and longer times on site.
This is really basic stuff. I can't believe the machine learning doesn't have enough info by now to see this pattern which clearly indicates that people like gadget26's site far more when they're sent there on a buy query than on an info query. Am I wrong? It just seems if the machine was this easily confused, we'd be seeing even more wacky bad SERPs than we've observed in recent months.
