Once your down the serps you naturally get abysmal results and algorithmically is impossible to tell the quality of the site.

This might be true in your specific case, but I don't see why it is "natural". I think that what's natural is quite the opposite. When you are ranked at the top, you are much more likely to get uninterested visitors who just click on whatever see first in SERPs.
