When the search engine receives a query or <a href=\"https:\/\/www.arimetrics.com\/glosario-digital\/query\">query<\/a> 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.<\/p>\n<p>Given the enormous amount of information available on the Internet, search engines are an essential technology today for the operation of this network.<\/p>\n\n<h2>Types of Search Engines<\/h2>\n<ul>\n<li><strong>Web search engines:<\/strong> These engines crawl and return web pages that they consider most relevant to the query made. They use algorithms that evaluate the quality and relevance of the content.<\/li>\n<li><strong>Image search engines:<\/strong> Specialize in crawling images online, presenting a mosaic of visual results that match the user&#8217;s search terms.<\/li>\n<li><strong>Video search engines:<\/strong> They analyze and classify videos, displaying those that best match the user&#8217;s query. Their algorithm may consider factors such as video length, number of views and associated tags.<\/li>\n<li><strong>File search engines:<\/strong> These engines focus on locating specific files based on their name, type or content.<\/li>\n<\/ul>\n<h2>How Search Engines Work<\/h2>\n<ol>\n<li><strong>Data indexing:<\/strong> Bots traverse the web continuously, gathering new information and updating existing information. This process is crucial to keep the database up to date.<\/li>\n<li><strong>Data categorization:<\/strong> The collected information is organized and classified using advanced algorithms that allow for efficient and accurate categorization.<\/li>\n<li><strong>Query processing:<\/strong> Upon receiving a query, the search engine performs a query in its database to find the most relevant information.<\/li>\n<li><strong>Presentation of results:<\/strong> The results are presented in a hierarchical manner, showing first those that the algorithm considers most relevant to the user&#8217;s query.<\/li>\n<\/ol>\n<h2>Examples of search engines<\/h2>\n<p>Among the <strong>main search engines<\/strong> we can find the following:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.google.com\/\" target=\"_blank\" rel=\"noopener\"><strong>Google<\/strong><\/a>: created by Larry Page and Sergei Brin in 1996, it is considered the world&#8217;s largest search engine.<\/li>\n<li><a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/bing\"><strong>Bing<\/strong><\/a>: owned by Microsoft, formerly known as Live Search, Windows Live Search and MSN Search.<\/li>\n<li><strong><a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/yahoo\">Yahoo<\/a>:\u00a0<\/strong>Currently uses the Bing engine in its searches.<\/li>\n<li><strong><a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/baidu\">Baidu<\/a>: t<\/strong>he leading Chinese search engine, with more than 600 million users.<\/li>\n<li><strong><a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/yandex\">Yandex<\/a><\/strong>: search engine for Russia and Russophone countries.<\/li>\n<li><a href=\"https:\/\/www.arimetrics.com\/en\/digital-glossary\/duckduckgo\"><strong>DuckDuckGo<\/strong><\/a>: an alternative to search engines focused on ensuring the privacy of its users.<\/li>\n<\/ul>\n<h2>Frequently asked questions about Search Engine<\/h2>\n<div class=\"geo-faq-block\">\n<details class=\"geo-faq-item\">\n<summary>What does Search Engine mean in digital marketing?<\/summary>\n<p>Search Engine refers to the concept described in this glossary entry: Definition: A search engine, also called a search engine, is a computer system designed to perform searches of files stored in a database through spiders or bots.
