What Are Search Engines and How Do They Work?

A search engine is a software system that enables users to find answers to their queries by presenting a systematic list of options. These options are a result of the search engine’s database.

The job of a search engine is to navigate the web by downloading web pages that match with a search query and then following the links on these pages to locate more new pages.


What are these search results called, you ask?

These search results which appear when you enter a particular query are called the Search Engine Results Page (SERPs). These results match the user’s query and can be in the form of pictures, videos, content, or a combination of all three. There are several search engines such as Google, Yahoo, Bing, AOL, et cetera, with Google being the most popular among them.

Though different search engines might present their information in distinct ways, they build on the same three basic principles, i.e., crawling, indexing, and ranking. These three principles and all the processes that make them up, come under the SEO process and its functions.
