Bing’s search engine ranking algorithms are not a traditional “recommender system” in that Bing only provides content to users as a result of their express request, rather than pushing content to users who were not expressly seeking it. That said, the main parameters of Bing’s ranking algorithms are published in the “How Bing Ranks Search Results” section of How Bing Delivers Search Results, which is available to Bing users in the EU. Bing also provides information on how it ranks and returns search suggestions in the Enhanced Search Experiences section of How Bing Delivers Search Results. Ancillary and supplemental search features, such as search suggestions, can be adjusted and/or deactivated through user search settings. Bing’s ranking algorithms apply equally to traditional search results and generative AI features that extend to Bing.
