PageRank algorithmGoogle Algorithm is a link analysis algorithm, named after Larry Page and used by the Google search engine, that assign a numerical weighting to each element of a hyperlinked set of documents.

In short PageRank is a vote by all the other pages on the web and about how important page is. A link to a page is counts as a vote of support.

Equation of PageRank is......

PR(A)=(1-d)+d(PR(T1)/C(T1)+…..+PR(Tn)/C(Tn))

  • PR(Tn)= each page has a notion of its own self value. PR(T1) for the first page in the web all the way up to PR(Tn) for the last page.
  • C(Tn) = each page spreads its vote out evenly among all of its outgoing links. The count or number of outgoing link for page 1 is C(T1), C(Tn) for page n and so on for all pages.
  • PR(Tn)/C(Tn)=I four page (page A) has a back link from page "n" the share of the vote page A will get is PR(Tn)/C(Tn).
  • d= all these fractions of votes is damped down by multiplying it by 0.85(the factor "d").
  • (1-d)= the (1-d) bit at the beginning is a bit of probability math magic so the sum of all web pages or PageRank will be one.

The PageRank of a page depend upon the PageRank of a page pointing to it.

Once the PageRank calculations have settles down, the normalized probability distribution (the average PageRank for all pages) will be 1.0.

PageRank of different sites:

  • The PageRank of Google is 0.9/1
    • The PageRank of facebook is 0.9/1
    • The PageRank of reddit is 0.8/1
