One of the major issues in internet browsing is search engine. And the name of Google really comes to mind in search engine. But have you ever wondered what this search engine is? And how do they work?


Maybe not and so in today's article I will discuss with you about search engine. Let's get started-

What is a search engine?


Search engines are basically a kind of software system through which our web searches are conducted. This means that if you search on the World Wide Web or WWW, the results you get are due to a specific search engine.

What is a Search engine? How does work?

And the search results that are shown in front of us are basically known as snakes. Search Engine Result Pages. And the information of so many sites is stored by the search engine in its own database. If someone searches for something, they bring information from there and present it.

How does search engine work?

Let's find out now what is search engine, but let's take a look at how search engine works. At this stage, the search engine is working on how to work -


As mentioned earlier, search engines are basically a part of the Internet that helps us navigate the Internet (called browsing). In this case, when we write something, based on the word, it makes a list of multiple results and displays it in front of us. However, looking at the search engine from the outside is not as simple as it seems.

How Search Engines Work — Really!

Crawl web pages -


Search engines perform a lengthy process before viewing the search results but you may not be able to catch it because it is in milliseconds. The main thing that happens in the beginning is web crawling. Web page crawling is a process by which search engines send some web robots to create a list of multiple contents for a specific keyword. Apart from these, crawlers also work to find new content and increase the rank of updated content.

Websites follow some rules for crawling or finding a web crawler. And these include-


And this is the basic idea of ​​relevance. When someone searches for a word, a crawler brings relevant issues to the searcher.

For example, if we search Amitav Bacchan Height by typing three keywords. The searches, however, will be somewhat similar, with the initial websites having three together and the later websites having any two or any one word together. Relevance is determined based on this.


It basically refers to how accurate and credible a content is for a particular word.

But the question is how Google or other search engines find it?

In fact, search engines look for links. That is, it depends on how many relevant links are attached to your content.


Do a Google search for Shakespeare's novels. But in front of you came Rabindranath's poem where the title is Shakespeare's novel.

Not at all. And a search engine always adheres to that. Rather, a web crawler works on whether the things inside are really satisfying to a searcher.

In this case, the higher the utility rate of the content, the higher the chance of ranking.

Indexed in search engines-


You must index something to get it in the search results. And the search engine crawler divides this data into different categories according to different words. When someone searches for that word, that list comes up in front of him in the search results.

How Do Search Engines Find, Crawl, and Index Your Content?

URL Inspection Tool-

At the very beginning of indexing we will need this inspection tool of Google through which we can add our site to that huge database of Google search engine. And if you ever notice that your webpage is not being indexed then there is nothing to worry about. Because you can easily request for the index very easily.


With the inspection tool you can get your content indexed by Google.

But would you like to show all the content i.e. contact page, about page in serpent or search result? Or is there a requirement to show all things?

Certainly not. Because there is no question of showing privacy and policy and contact pages. You can use the robots.txt file to convince the crawler which pages should be indexed and which should not. However, there is no reason to panic. Because it will not hurt the site ranking.



This is the last step in the functioning of search engines. When we search for something. Just then, search engine crawlers searched and refined its entire database, bringing out the best and most relevant. And before it comes, the web crawler makes a specific list based on relevance and displays the results in front of us. Where one website is at the top and another is at the bottom, this is called ranking.

How to Improve Your Google Rankings (Without Getting Penalized)

For a webpage ranking, you must know how search engines rank or work. In this case, the following things must be taken care of.

Relevance of backlinks-

In this case, the more links you add, the better the ranking. Does that mean I will just add the link? Do not add only what is relevant. If not, there is no need.

Page Speed-

The ranking also largely depends on how quickly the website appears in front of a searcher. A recent statistic found that 40% of people return to a website because of its low speed. So if you want to get good ranking, you have to keep in mind the page load.

Freshen- ing-

How often you update your content from time to time, or how long ago you did it also plays an important role in ranking. However, if the case is that you ranked a content 5-6 years ago and spent a few years without any change in that content. Then of course your content will no longer be on top. You can try now to get proof of the matter.

Mobile friendliness-


Sometimes it may be that our website is displayed only on PC or laptop but not on mobile. In this case, there is a possibility of facing a big threat. Because most of the visitors of a website (about 80%) but the website is visited by mobile. In this case, if your site is not displayed on mobile, you will lose that 80%, as well as Google will reduce your ranking a lot.

To avoid that we should use responsive or mobile friendly sites. And to pay special attention to the creation of website templates or in the case of website development.

As mentioned earlier, search engines are basically a part of the Internet that helps us navigate the Internet (called browsing).

3 Methods to Verify Your Website is Mobile Friendly

Again, when we give any information to this search engine while browsing the internet, it goes straight to the server or database of the search engine. And when a person searches for a keyword related to our content, some search engine programs (or algorithms called bots) present that content to us from the search engine database.
