Estimated read time 6 min read

Search engines are one of the most important things in the world. Without them, practically today, we have no way to go, as they help us in every aspect of life. Therefore, there are over hundreds of search engines in the world offering services to ease our life,

And among them, Google tops the chart with over 88% of the market belonging to their name. From business to education, they help all people and allow them to grow in their respective fields.

The recent data that was published on search engines in June 2023 suggested that Google has the most visits, with people visiting the website over 106.5 billion times, which is ten times the population of India.

Hence, the question comes of how Google can work so fast and predict my searches. Well, they use auto predictions that allow you to suggest common queries when you type the words in the search box.

Further, they consider the language and location of the query to give definite results.

It’s still confusing, right? Okay. Let’s know them in the next section.

What Are Search Engines?

Search engines are the gateway to the web, where people look for content among various web pages that are available online. They offer a fundamental right to the people to get free and open access to information and free expression.

Search engines thrive in delivering the most useful and relevant information for users seeking from the search portal. Further, they ensure that the privacy and safety issues of the users are not breached. Thus, maintaining a balance in offering the right services and accessibility to pages.

We can summarize their usefulness in the following points –

  • They provide credible and authoritative data to user’s search query
  • They ensure that the search results are accurate with the users, so even if the information is less credible, they still show in the search results.
  • Further, they aim to avoid promoting bias or potentially misleading information to users, as they prefer to keep information first.  
  • They promote information based on local and international law. Also, they try to uphold the fundamental right while they are looking to give access to the pages online.
  • Further, they protect users from harmful and offensive content and promote the practice of safe search.
  • Also, they are transparent about their principles and practices, which allows businesses to rank their content in search engine algorithms and reap the benefits of high rankings.

How do Search Engines Work?

One of the biggest questions we seek to unearth is how do search engine works. The answer to that question is the use of automation, which allows one to explore the web pages that are regularly added to their index.

The automated software adds most of the pages in the search engine area after the web exploration done by the automation software.

Consequently, there are three stages that showcase how the search engine works –

  • Crawling: The search engine downloads the texts, images, and videos from the pages found on the internet through automated crawlers.
  • Indexing: The search engine then analyzes the text, images, and videos found on the internet and stores them in the search engine database in the form of an index
  • Serving search results: After a word or a sentence is typed into the search box, the search engines provide the information which is relevant to the user’s query.

Let’s know about the stages in a broader way –


Every search engine today has a web crawler that helps them access relevant online pages. These crawlers roam the internet, look for new and updated pages, and add them to the list of known pages. It is also known as URL discovery.

Further, in this way, other pages also get discovered from one known page, and then the web crawlers get the list of pages they need to travel and find the relevancy of the information.

Mostly, web crawlers are known as bots, like Google has a Google bot. Similarly, Bing has a Bing bot. Most bots use an algorithmic process, which helps them to determine the pages they need to crawl and how many pages they need to fetch from one website.

In order to enhance the quality of the research, the crawlers are programmed to do proper research, which helps them to rank the website on the search engine.


The indexing process begins after the web crawlers collect all the information. It is the stage where the search engines start to analyze the texts, images, and videos from the internet.

All the page attributes are thoroughly checked and then ranked on the search engine. Further, the search engine showcases canonical or duplicate pages that are present on the internet.

They group similar pages and then select the most representative of the group, and other pages serve in different contexts. Mainly users use the mobile version of the web browser.

Further, the search engines collect signals from the canonical page and use them when we search in the search engines. The signs include language, locality of the content, etc.

Serving Search Results

This is the last stage that showcases how the search engines work. It is the stage where the search engines return the search result to the users and allow them to access relevant information.   

Majorly the relevancy of the information is determined by various factors, which include location, language, and electronic device they are using for the search result. Further, the search engines also use previous search results to determine the relevant search result for the user.

Further, search engines are also responsible for showing local results, where you can view the local shops, which is great for local businesses.

Well, this is how the search result works, and search engines showcase the information you search from their database.

All Search Engine Are the Same

Even though Google as a company leads the way as a search engine, other search engines like Bing, Yahoo, and others use a similar process for presenting information to users.

Even the use of automation serves as the reason why you see others at the top than the others.
