Search engine

A search engine is a software program or tool designed to search, retrieve and display information from the World Wide Web (WWW). The search engine processes users’ queries and provides a list of relevant web pages, documents, images, videos, and other content based on the search terms entered. 

Search engines use web crawlers or spiders to scan the internet and collect and index web pages and other content. The indexing process involves analyzing the content of each web page, including the text, images, and metadata, and categorizing it based on specific algorithms and ranking factors. 

Users can search for information on search engines using keywords or phrases describing what they seek. The search engine then uses its algorithm to match the user’s query with relevant web pages or content and displays the results in order of relevance and importance. 

Some popular search engines include Google, Bing, Yahoo, Baidu, and Yandex. Search engines play a crucial role in connecting users to the vast amount of information available on the internet. They are essential for businesses looking to increase their online visibility and reach potential customers.
