What is a Search Engine?

It is a type of service by which users can access websites via the World Wide Web (WWW). There are so many search engines available to use. Every search engine carries different kinds of abilities and features.

Few people know about the first search engine ever developed. And it is Archie, which is used to search FTP files. Veronica, known as the first-ever text-based search engine, was accessible to ordinary people. Today, one of the giant search engines is Google. It began in 1998 and is still providing excellent service today.

Google is one of the most used search engines. There are more than 4 billion people. Yes, you read it correctly and do not be surprised by it. Because Google was ready to adopt new things to make search results perfect day by day. Google works to improve its results to make them accurate and reliable.

There are many alternative search engines known as Bing, Yahoo, AOL, DuckDuckGo, Baidu, and so many.

So, before you know how search engine works. You should know about three basic points.

  • Web crawlers, also known as spiders or bots, collect website information across the internet.
  • A database is a place where search engines store their data.
  • Search Interfaces: act as a bridge between the user and the database. It is the reason behind search results.

How Do Search Engines Work?

A Web crawler, search interfaces, and databases are the basic components of the search engine. We cannot imagine a search engine without any one of them. Search engines have plenty of web pages for one query. Showing search engine result pages (SERPs) for one query is not an easy process. It is all decided by the search engine’s algorithm which web pages could be best for queries.

It is understandable. A search engine follows three basic phases to offer the best results to its consumers. We will check them one by one.


Most people have no idea about crawling and indexing (we will talk about it later). Crawling is an initial process by which search engines discover new web pages and websites. First of all, web crawlers investigate those pages. Bots follow and scan backlinks, referring to them for the next step in the process.


After the crawling process, the search engine validates web pages. And stores them in its database. This process is known as indexing to show web pages in SERPs. And if your sites will not index, then the webpage will not appear in search results.

Let it Understand by a Simple Example.

If you have an online local cake-making website. Google will not show your website under the “cake near me” keyword phrase until your website is indexed. So, it is a fundamental step, and you can skip it. Skipping it means you do not want an online business, to be honest.
