You suppose Google has a "test detection" heuristic? For example, if we see a completely unique word suddenly appear on 2 domains that themselves have no possible meaning or prior reference, and everything is the same except 1 variable, then we'll just randomize the results? Seems like a test scenario itself might be algorithmically detected and f----ed with.
