You probably know that Google will group two results together when they are both from the same site—indenting the second of the two results indented beneath the first one. Let’s say, for sake of argument, that a competitor of yours is ranked #1 and #2. But did you know that the listing ranked #2 is most likely not actually #2, rather something between #3 and #10? The second, indented result could very well have as its “true” position #10.
