(22)Traders enabling consumers to search for goods and services, such as travel, accommodation and leisure activities, offered by different traders or by consumers should inform consumers about the default main parameters determining the ranking of offers presented to the consumer as a result of the search query and their relative importance as opposed to other parameters. That information should be succinct and made easily, prominently and directly available. Parameters determining the ranking mean any general criteria, processes, specific signals incorporated into algorithms or other adjustment or demotion mechanisms used in connection with the ranking.
