|DS: Does Google have different ranking factors for different industries? |
MC: We have looked at topic-specific ranking. The problem is it’s not scalable. There’s a limited amount of that stuff going on — you might have a very spammy area, where you say, do some different scoring.
What we’re doing better is figuring out who the authorities are in a given category, like health. If we can figure that out, those sites can rank higher.
DS: How many different categories?
