Ranking algorithms are methods used to order items based on their relevance or importance. They are commonly applied in search engines, social media platforms, and recommendation systems to determine which content should be displayed first. These algorithms analyze various factors, such as user behavior, content quality, and contextual relevance, to produce a ranked list of results. One well-known example of a ranking algorithm is the PageRank algorithm, developed by Larry Page and Sergey Brin for Google. It evaluates the quality and quantity of links to a webpage, helping to determine its authority and relevance in search results. Other algorithms may focus on different criteria, such as user engagement or personalization.
