What is search engine ?

A search engine is a software application that aids in searching the internet for information. When searching, it displays the most relevant results by indexing web pages and other online content, and organizing them according to relevance..

 

A simplified explanation of search engines:

• Crawling
• Indexing
• Ranking
• Displaying Results

Here’s a simplified breakdown of how search engines work:

1. Crawling: Whenever a search engine collects information about a website, it uses an automated program called a crawler or spider to browse the web and find new pages. These crawlers follow links from one page to the next, gathering information about each page as they go.
2. Indexing: An index is a massive database that includes all the web pages and their associated information (keywords, metatags, links, etc.). The search engine then analyzes the content of the pages it discovers and adds them to its database.
3. Ranking: Users enter relevant search queries into the search engine, and the search engine retrieves and ranks relevant pages based on a variety of factors, including relevance to the query, authority, quality of content, and user engagement..
4. Displaying Results: On the search results page, the search engine shows the user the results of the search in the form of links (often with titles and snippets). Users can click on the links to visit the web pages which seem most relevant to their search.

In order to ensure that users receive the most relevant and useful results for their queries, popular search engines such as Google, Bing, Yahoo, and others use complex algorithms. In order to combat spam and low-quality content, they continually update and refine these algorithms.
