I'm not sure if there is really anything new here. It appears to consolidate parts of the original patent filing of the same name, with the second pagerank patent, Method for scoring documents in a linked database [patft.uspto.gov].

There are some very subtle differences in language in a few places, and the main additions that aren't in the first or second pagerank patents, are the addition of a few extra paragraphs in the "Summary of the invention" section.

But the section about "real usage data" is in the second pagerank patent, which was granted in 2004.
