engine is powered by robots called crawlers.<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p><span style=\"font-weight: 400;\">When an Internet user performs a search on the Internet, he or she must use a search engine. The surfer will then have to insert keywords so that the search engine can display relevant results related to the requested information. Once the keywords have been entered, the search engine scans all the sites containing the requested information. <\/span><b>To find relevant results, the search engine relies on robots to sort and analyze sites compatible with the requested information.<\/b><span style=\"font-weight: 400;\"> To do this, the robots use precise criteria to sort the websites, find the best ones and display the results. <\/span> <\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"A_search_engine_relies_on_complex_algorithms\"><\/span><span style=\"font-weight: 400;\">A search engine relies on complex algorithms<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p><b>A search engine uses complex algorithms to identify the nature of the information or documents published on the Internet,<\/b><span style=\"font-weight: 400;\"> Such as photos, music, videos\u2026 Naturally, the aim of a search engine is to provide fast results with content relevant to the queries made by Internet users.

The search engine gathers all the information present on the various online platforms<\/strong>. This feat is performed by crawlers or spiders (the robots that help search engines carry out searches). Once the information has been gathered, the crawlers send it to the index so that the search engine can index it.  <\/span><\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Indexing\"><\/span><span style=\"font-weight: 400;\">Indexing<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p><span style=\"font-weight: 400;\">When the engine brain or index receives the information gathered by the crawlers, it moves on to indexing. This stage consists of evaluating all the sites gathered, then organizing and classifying them according to the valuable content of each one. <strong> Once this evaluation is complete, the search engine can display results based on the quality of each website\u2019s content.<\/strong><\/span><\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_does_a_search_engine_determine_a_websites_ranking\"><\/span><span style=\"font-weight: 400;\">How does a search engine determine a website\u2019s ranking? <\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/botnation.ai\/wp-content\/uploads\/2022\/12\/Moteur-de-recherche-Google-sur-un-ordinateur-portable.jpg.webp\" alt=\"Google search engine on a laptop\" class=\"wp-image-42864\"><\/figure>\n<\/div>\n<p><span style=\"font-weight: 400;\">A search engine uses robots to analyze each site associated with a user\u2019s search terms. These robots use precise criteria to assign a quality rating to each site linked to the query. Here are the basic criteria used by these robots to define a site\u2019s ranking in the results displayed.  <\/span><\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_popularity_rating_of_the_page_or_website\"><\/span><span style=\"font-weight: 400;\">The popularity rating of the page or website<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p><span style=\"font-weight: 400;\">This is the most important criterion for determining the ranking of a page or website. The crawlers take into account the number of visitors and backlinks pointing to the site. <\/span><b>The greater the number of visitors and backlinks, the higher the ranking given by search engines.<\/b><\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Site_content_and_SEO\"><\/span><span style=\"font-weight: 400;\">Site content and SEO<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p><b>For search engines to qualify a site as relevant, its content must be valuable and of high quality.<\/b><span style=\"font-weight: 400;\">. To achieve this, the site manager must write content with relevant keywords so that the search engine ranks it among the best. Today, most marketers opt for SEO, or natural search engine optimization, to optimize their site\u2019s content and guarantee a higher ranking in the results displayed. The crawlers will analyze the keywords according to the requested query and rank the sites with optimized, quality content. <\/span> <\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Organizing_content_on_the_website\"><\/span><span style=\"font-weight: 400;\">Organizing content on the website<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p><span style=\"font-weight: 400;\">This is a criterion that Google, like other search engines, takes into account in order to identify pages likely to satisfy users. Site owners must therefore organize their content, such as titles, images, videos, external links\u2026 <\/span><b>Search engines evaluate site organization to ensure that the page displayed adapts to all device screens, and that the result provides the best ranking of sites with search-related content. <\/b><span style=\"font-weight: 400;\">This criterion contributes to offering users results with relevant content and a quality experience.<\/span><\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Which_are_the_worlds_most_popular_search_engines\"><\/span><span style=\"font-weight: 400;\">Which are the world\u2019s most popular search engines?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p><span style=\"font-weight: 400;\">There are many different search engines used by Internet users to search the Web.
