We all use Google.com or any other search engine to find some info about some words , places, tools or any thing ! and we saw some websites are in the first page and some others are in next pages of the Google.
Today I want to write about the reason of this rating system and answer to this question that why some websites has higher rating and are in the first page of the Google.
Google.com has a page rank system that evaluate website stats and content and visitors and many other methods that are secret and after checking all stats each website give a rank for each page.
Please note that the Google rank is for pages not for website ! This page ranks is between 0 and 10 that top websites has higher numbers. For example Google.com page rank is 10.
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. Sergey Brin had the idea that information on the web could be ordered in a hierarchy by “link popularity”: a page is ranked higher as there are more links to it It was co-authored by Rajeev Motwani and Terry Winograd. The first paper about the project, describing PageRank and the initial prototype of the Google search engine, was published in 1998: shortly after, Page and Brin founded Google Inc., the company behind the Google search engine. While just one of many factors that determine the ranking of Google search results, PageRank continues to provide the basis for all of Google’s web search tools.
PageRank has been influenced by citation analysis, early developed by Eugene Garfield in the 1950s at the University of Pennsylvania, and by Hyper Search, developed by Massimo Marchiori at the University of Padua. In the same year PageRank was introduced (1998), Jon Kleinberg published his important work on HITS. Google’s founders cite Garfield, Marchiori, and Kleinberg in their original paper.
A small search engine called “RankDex” from IDD Information Services designed by Robin Li was, since 1996, already exploring a similar strategy for site-scoring and page ranking. The technology in RankDex would be patented by 1999 and used later when Li founded Baidu in China. Li’s work would be referenced by some of Larry Page’s U.S. patents for his Google search methods.

SERP Rank
The Search engine results page (SERP) is the actual result returned by a search engine in response to a keyword query. The SERP consists of a list of links to web pages with associated text snippets. The SERP rank of a web page refers to the placement of the corresponding link on the SERP, where higher placement means higher SERP rank. The SERP rank of a web page is not only a function of its PageRank, but depends on a relatively large and continuously adjusted set of factors (over 200), commonly referred to by internet marketers as “Google Love”. Search engine optimization (SEO) is aimed at achieving the highest possible SERP rank for a website or a set of web pages.
With the introduction of Google Places into the mainstream organic SERP, PageRank plays little to no role in ranking a business in the Local Business Results. While the theory of citations is still computed in their algorithm, PageRank is not a factor since Google ranks business listings and not web pages.
The Alexa.com also has own ranking system too, each website has a ranking number as a Google ranking system but lower number has higher rank in Alexa.com
