A search engine is a software system that finds web pages that match a web search. They search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories.

Unlike web directories and social bookmarking sites, which are maintained by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Any internet-based content that cannot be indexed and searched by a web search engine falls under the category of deep web.

The most popular search engines in the world are Google, Bing, and Yahoo. These search engines use a variety of factors to determine the relevance of a web page to a search query, including the page’s title, content, keywords, and backlinks.

Search engines are an essential tool for finding information on the internet. They allow us to quickly and easily find the information we need, without having to know the specific website where it is located.
