We all had our suspicions that Google no longer used PageRank. Well, most of us thought Google just doesn't use it to the level they did a year or two ago. Mike Grehan says Google does not use PageRank period. He kind of implied that Apostolos said Google does not use PageRank at all. In the interview, Mike quoted Apostolos as saying, "Have they implemented PageRank? The answer is no." He goes on to explain that "The importance [of PageRank] has diminished because PageRank is just one piece of the ranking algorithm over there. The ranking algorithm is so much more complex now. And PageRank is just used when they want to break ties."
I started a thread on this specific topic at Search Engine Watch Forums.
