Just like this if we want to know someone or something using any robotic media like a computer or web we should set up a program that is a searching program.

How does a Web Search Engine Work?

In short, a Web Search Engine receives the data that users entered (it may be a word, an audio signal, or an image), then it crawls the whole of the web. Then, copies the data from different websites and shows the users the estimated results. Usually, they try to give the exact information according to the user’s query. The crawling bot crawls the whole of the Web within a very short time and uses an algorithm to rank the displayed data. The algorithm is a set of data by which it does its work accurately.

Most of the search engines work by means of an automated program named Crawler. A huge web pages crawl in a few seconds using the Crawler. In this process, the Search robot access the webpages and try to read the data on the landing page, get it and stored their database.

Storing the data in their database known as indexing. When a searcher searches a word or a group of words in the Search box, it shows the best search results from their index page to SERP according to their ranking algorithm. Here we describe all the working sequence step by step.

First Step

Third Step

Fourth Step
