Hey, guys, in this world a lot of bloggers that want to rank their posts google no.1 position but they don’t know how to rank posts or articles,

But if you want to rank your post or article, no.1 position so understand search engines how search engines work.

In this article, I will tell you how does a search engine work step by step. Actually, google search engines work using their own web crawlers, search engines crawl hundreds of billions of sites pages. Web index bots or insects are incessant names for these web crawlers.

A web crawler explores the web by downloading site pages and following connections on those locales to observe new pages that have been added.

What is a Search Engine

A search engine is an online library where information can be found. By entering search terms, the search engine will provide you with a list of relevant websites where, if all is well, you can find the answer to your question.

This is called the Search Engine Results Page, or SERP. Well-known search engines are Google, Bing, Yahoo!, Ecosia, and DuckDuckGo.

Types of Search Engine

Index search engines collect information on the Internet automatically, using special robots that visit web pages. They perform comprehensive keyword searches. Examples of such search engines are Google, AltaVista, HotBot, Yandex.
An index search engine has three main components:

  • Agent (spider or crawler)
  • Search engine database
  • Search engine

Index search engines

Work on one general principle. First, the agent starts scanning the network from a specific address.

Indexed copies of documents are created on the server, a kind of auxiliary file.

Then the saved documents are viewed, hyperlinks from these pages are determined, and the transition to new pages is made through them.

After saving copies of the found documents, the whole process is repeated.

All web pages indexed by the search engine go to the database, which allows the user who makes a request to search for the necessary information, instantly to get links to it.

Catalog Search Engine

List web search tools contain a specifically organized index of servers and are frequently recharged physically by arbitrators.

These systems are structured in the same way as the subject catalog of a regular library. Links in them are stored on the topic of categories.

Starting at the main catalog page, you select the link that denotes the main category, and then on the subsequent pages specify the subcategories until you reach links to specific pages.

The directory is usually categorized into subdirectories, which in turn can be subdivided into smaller subdirectories, etc. Yahoo is the main example of a directory.

Index search engines and search directories differ in the same way as content and alphabetical index in a book.

The purpose of both the content and the alphabetical index is to help you find the section you need in a book. Content is an example of cataloging.

The alphabetical index is an example of indexing. The reader finds the required term in the index and receives the number of the page on which it appears.

Metasearch engines

Metasearch engines are systems that use databases of other search engines to search. They send a request simultaneously to several search engines, directories, and sometimes to the so-called invisible (hidden) web – a repository of online information not read by traditional search engines.

In the wake of gathering the outcomes, the metasearch framework eliminates copy joins and, as per its calculation, consolidates the outcomes in a typical rundown.

An example of such a system is the Russian solution Nigma, which uses Google, Yahoo, Aport, and Yandex for search.

Specialized Search Engines

Specialized search engines, unlike general search engines that search for any information of interest, are looking for information of a certain type, for example, images, books, organizations, people, that is, they work in a specific area.

How Google Search Engine Works Step by Step

Here I will explain to you how does a search engine work step by step:

Crawling, Indexing, Ranking

Arriving at Chapter 2 of our SEO Beginner’s Guide. As we mentioned in our first chapter ( What is SEO? ), search engines are answer engines. Search engines are there to collect, organize and review all content on the internet. All this is done to present the most relevant answers and solutions to the end-user.

To get back in Google’s search results, your website must first be visible to the search engines. If your website cannot be found by the search engines, your website will never appear in the search results.

How does a Search Engine Work?

Search engines have 3 primary functions:

  • crawl
  • index
  • rank

What is ‘Crawling’?

Can a search engine find your pages? Google scans a huge number of websites. They do this with the help of robots that scour and assess millions of websites every day. We also call this ‘scanning’ and ‘crawling’. The robots cannot read letters, but only recognize code fragments that are placed behind your text in WordPress.

While scanning and crawling the website, these robots recognize what the texts are about. This is because certain keywords, which the visitor is looking for, are included in different places in the text (title, headers, meta descriptions).

One way to find out how many pages a search engine has included in their index for your website is to perform a ‘Site search in Google’. This goes as follows:

Go to
Google now gives you an overview of all pages that are currently included in the index of the search engine. In our case, it concerns 559,000 pages that are included in Google’s index.

This number gives you an indication of which pages the search engine has currently indexed.

If your website does not yet appear in the Google index, it can be for several reasons:

  • Your website is just new and hasn’t been crawled yet
  • Other websites are not linking to your website yet
  • It’s difficult for Google’s robots to navigate your website
  • Your website contains coding that prevents your website from being crawled by a search engine
  • Your website has been penalized by Google for using spammy techniques

Tell Google the Best Way to Crawl Your Website

After doing a site search, you may find that some of your most important pages are not listed in Google’s index. Or that some pages that you actually don’t want to appear in the index, are indexed.

Fortunately, there are optimizations that you can apply so that your most important pages are included in the index and the least important pages are not included in the index.

The question now, of course, is how to tell the search engine which pages to crawl and which not to crawl.

Robots.txt file

Who do you say?

Robots.txt file can be found by entering the following URL in your search bar:

In this file, you can give the commands for the search engine which pages you do and do not want to crawl. In addition, you can also include in this file the speed at which the search engine should crawl your website.

How does Google Handle robots.txt files?

  • If the Googlebot can’t find your website, then Googlebot will continue to crawl your website
  • If the Googlebot does come across a robots.txt file, the Googlebot will follow these suggestions you made and continue to crawl your website
  • If the Googlebot encounters an error while Googlebot tries to find your robots.txt file and cannot determine whether a robots.txt file is present, then your website will NOT be crawled.

Optimize Your Website For Crawl Budget

The crawl budget is the average number of URLs that Googlebot will crawl before leaving your website. So optimizing your crawl budget ensures that Googlebot won’t waste time crawling unimportant pages. Crawl budget is often an important factor for websites with tens of thousands of URLs.

However, it doesn’t hurt to exclude the URLs that are not relevant.

What is meant by a search engine index?

Search engines store all the information they come across. All this information is stored in an index. This is a huge database of all the content they have come across online that is good enough to present to the visitors.

Robots assess your website on how easy it is, for example, to navigate through your website and how readable the texts are for the visitor. After the content on the page has been crawled, you can have the page included in Google’s search results by indexing the page.


When the page is indexed, it will be rated for its content. The content largely determines on which position Google will rank your page.

In addition to the content, there are other ranking factors based on which Google can/will assess the content.


Actually, google search engines work using their own web crawlers, which is what their name implies. Yes, web index bots or insects are the names for these web crawlers.

There are many different types of crawlers that search engines like google use. These items are incessant, which means they are never very far from their goal.

They explore the web and find sites that need to be crawled.

They accomplish this goal by creating an index that is updated every day.

It’s a fast-paced world and search engines are constantly on the move to keep up with the changes.

They have to be if they want to be successful. If you have any questions or concerns, please don’t hesitate to reach out to us.
