What is a Search Engine?

A Search Engine is a software system designed to search out the information from the World Wide Web according to the user’s query. Search engines allow users to search the internet for content using keywords. When the search engine receives a query or makes a query in the database offering the result on a results page. If there are several results, they are hierarchical according to their importance.

Search engines often change their algorithms to improve user experience. They aim to understand how users search and give them the best answer to their queries. This means giving priority to the highest quality and most relevant pages.

How Does a Search Engine Work?

There are three key steps to how most search engines work:

1. Crawling: Crawls the web finding pages to add to their database.

Search engines have no. of a computer program that is responsible for finding information that is publicly available on the internet & these programs are also known as crawlers. These programs scan the web and create a list of all the websites.

Then visit each page of the website and by reading the HTML code they try to understand the:
1. The structure of a page
2. The type of content 3. The meaning of a content
4. When it was created or updated.

2. Indexing: Once a website has been crawled, it’s time for it to be added to the database.

Store and organize the content found during the crawling process. The search engine will try to understand and categorize the content on a web page through ‘keywords’. Once a page is in the index, it’s in the running to be displayed as a result of relevant queries.

Search engines don’t store all the information on their index but they keep things like:

1. Title and description of the page.
2. Type of content
3. Associated keywords
4. No. of incoming and outbound links.

3. Ranking: Search results are ranked based on several factors. These may include keyword density, speed, and links. The search engine aims to provide the user with the most relevant results. Ranking depends on the search engine algorithm.
