Have you ever wondered how many times per day you use Google or any other search engine to search the web? Is it 5 times, 10 times, or even sometimes more? Did you know that Google alone handles more than 2 trillion searches per year? The numbers are huge. Search engines have become part of our daily life. We use them as a learning tool, a shopping tool, for fun and leisure but also for business. It’s not an exaggeration to say that we reached a point that we depend on search engines for almost anything we do.

And the reason this is happening is very simple. We know that search engines and in particular, Google has answers to all our questions and queries. What happens though when you type a query and click search? How do search engines work internally and how do they decide what to show in the search results and in what order?

Search engines are complex computer programs. Before they even allow you to type a query and search the web, they have to do a lot of preparation work so that when you click “Search”, you are presented with a set of precise and quality results that answer your question or query. What does ‘preparation work’ includes? Three main stages; The first stage is the process of discovering the information, the second stage is organizing the information, and the third stage is ranking.
