Google has ranked ShaShinKi.com as a Page Rank 4 website now!
It was still Page Rank 3 last month and many months before. I remember it has a mixed of Page Rank 3 and 4 few months ago, but suddenly drops to all Page Rank 3 one or two months ago. Two days ago, it has a mixed of PR3 and PR4 again, but weighted more towards PR3 (so average still a PR3 site).
Just a few minutes ago, I checked again with 43 unique datacenter of Google and it has FULL PR4 ranking! Where do I checked?
PageRank is a link analysis algorithm that assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of “measuring” its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted by PR(E).
PageRank was developed at Stanford University by Larry Page (hence the name Page-Rank) and Sergey Brin as part of a research project about a new kind of search engine. The project started in 1995 and led to a functional prototype, named Google, in 1998. Shortly after, Page and Brin founded Google Inc., the company behind the Google search engine. While just one of many factors which determine the ranking of Google search results, PageRank continues to provide the basis for all of Google’s web search tools.
