Many webmasters, companies and marketers have been working hard for getting higher page rank and generating sales. The purpose of this article is to present an overview of search engine’s scalability and Google’s creation. A fascinating factor about this development is to understand why Google obtained a huge success. Why search engines play an important role in surviving of our online marketing? Why is it so important to have an overview about scalability of a search engine? Before answering to these questions lets have an overview of search engines evolution in the past.

During the past years Search engine technologies have been scaled up dramatically in order to keep up with increase of websites on the internet. If you look at search engine evolution historically, you will explore that the first search was created in 1994. This search engine was called World Wide Web Worm. Its job was to index many web sites and documentations.  During the years 1997 to 2000 some changes had happened in search engines. Google was developed and the purpose of its development was to create a search engine that can crawl as many pages as possible per day. Google was a prototype of two students. This was a clever designed search engine prototype. The students got their grade and this prototype build a great future for them and now it is a multibillion dollar company that is even making rules on the internet. Although the internet is a free realm of internet users around the world, but in some ways you do not sense that you are free to do whatever you want with your website. Because Google makes rules and get you to obey them otherwise you are out of the empire of this search engine. You have no choice but following Google’s rules. Do you have to obey these rules? Why blakchat is bad and whithat is good? What happens if you do not obey Google’s rules? Your site gets banned and those millions of people who search on Google, won’t be able to find your website based on your keywords.

This search engine, Google was written in C and C++ and has two main features such as: calculation of link structure of a web page ( page rank) and using link to improve the search results. There are over 200 factors in Google’s algorithm.

According to Google, page rank creates order on the World Wide Web. Page rank is calculated applying a simple iterative algorithm. A page rank is calculated based on the amount of visitors that visit a webpage. A visitor can be a returning visitor or a random visitor.  There are other factors that determine a page rank’s calculation such as anchor text placement, keyword density, amount of back links to a website and much more that is beyond of the scope of this article.

Google’s engineers have been able to make Google as scalable as possible. That is why this search engine  is able to index as many websites and documents possible. This scalability helps our websites to be more visible on the internet.

Google is also a research tool for scholars and researchers. Google is created to scale and evolved to succeed in bottlenecks challenges. The indexing, crawling and sorting algorithm have made the visibility of websites more possible.
