Just about every page ranks for some phrase or other. In my case, the bots seem to be hitting some pages that rank for essentially nothing, generate very little traffic from search.
If this botnet is testing a Negative SEO offering, then they ought to test on an obscure phrase that is not competitive, because such a SERP will not have a lot of variables, e.g. regular competitive SEO activity.
