Sixty-two sites moved up and 58 moved down significantly in the category. That's a lot of movement in the top 200 sites. In all we’re working with 120 sites.
But what about the sites that DIDN'T move significantly? What if your findings say that XYZ is a factor in the sites that moved down, but if the other 80 sites that you DON'T analyze have that same factor, then what?
