How PageRank Works and Is It Calculated
In the past, there was only the green bar on the Google Toolbar that gave indications regarding the presence of a value ranging from 0 to 10. Behind this indication, however, lies a refined calculation.
How does Google work in this case? It goes from considering the simple number of links received to the value that the single link has, so as not to flatten all the backlinks on the same level. The calculation of PageRank is expressed by a formula published in the already linked official document.
PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))
The PR of page A is given by the value of all pages that go from T1 to Tn in relation to the parameter d. That is, it is a damping factor set at 0.85. In short, without going too much into the details of the kenya whatsapp number database algorithmic formula of PageRank, we can say that this metric does not simply evaluate the quantity of links by normalizing the number of links on a page.

Rather, it values web pages by evaluating the aforementioned damping. That is, the PageRank is only partially transmitted from page A to all those that receive links. This process of link juice – the flow of PageRank through websites – is depicted in the image from polemicdigital.com .
There are still some PageRank Checkers but December 6, 2013 was the last time an update was recorded inside Google Toolbar. In short, it is still necessary to carry out a work of understanding and analysis of the logic of PageRank without getting stuck on the pure and simple number.
