Impact on Google PageRank

1)Frequent content updates don’t improve Page Rank automatically. Content is not part of the PR calculation.

2)High Page Rank doesn’t mean high search ranking.

3)DMOZ and Yahoo! Listings don’t improve Page Rank automatically.

4).edu and .gov-sites don’t improve Page Rank automatically.

5)Sub-directories don’t necessarily have a lower Page Rank than root-directories.

6)Wikipedia links don’t improve PageRank automatically (update: but pages which extract information from Wikipedia might improve PageRank).

7)Links marked with nofollow-attribute don’t contribute to Google PageRank.

8)Efficient internal onsite linking has an impact on PageRank.

9)Related high ranked web-sites count stronger. But: “a page with high PageRank may actually pass you less
if it has more links, because it’s spread too thin.”

10)Links from and to high quality related sites have an impact on Page Rank.

11)Multiple votes to one link from the same page cost as much as a single vote.
