March 8, 2017

From a Digital Marketing point of view, it’s a vital and necessary to know all the Google updates and how Google Algorithm makes the search engine so accurate for the users. There are a lot of specific mathematics and logics behind these algorithms. We need to understand these very carefully. From SEO perspective, it is required to know why Google launches new update every now and then. It’s because Google always tries to improve the user experience. This is the ulterior objective. They work on providing a better result to the user to get the ultimate search satisfaction.

Google has modified its search algorithm a lot of times. These modification gives the business owners a challenge and a chance to rank higher in the search engines. Getting better rank has become a difficult task, but not an impossible one.

Let’s discuss the major algorithms and updates and their significant roles on Google search engine.

PageRank:

This algorithm defines the page rank of page A, which is determined by the page-rank of those pages which linked to page A. This system of ranking the pages was developed by Google’s founder Larry page and Sergey Brin at Stanford University. It is given by

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

Where

PR (A) is the PageRank of page A,

PR (Ti) is the PageRank of pages Ti which link to page A,

C (Ti) is the number of outbound links on page Ti and

d is a damping factor which can be set between 0 and 1.

PageRank is nothing but a system of algorithms which calculates the link votes of a page from various sources. PageRank algorithm determines which pages are more valuable and which ones are less valuable per the above formula. Google uses PageRank algorithm along with text-matching technique to find pages that are both essential and relevant to your search.
