The description of the main parameters determining ranking should also include an explanation of any possibility for business users to actively influence ranking against remuneration, as well as an explanation of the relative effects thereof. Remuneration could, in this respect, refer to payments made with the main or sole aim to improve ranking, as well as indirect remuneration in the form of the acceptance by a business user of additional obligations of any kind which may have this as its practical effect, such as the use of services that are ancillary or of any premium features. The content of the description, including the number and type of main parameters, can accordingly vary strongly depending on the specific online intermediation services, but should provide business users with an adequate understanding of how the ranking mechanism takes account of the characteristics of the actual goods or services offered by the business user, and their relevance to the consumers of the specific online intermediation services. The indicators used for measuring the quality of goods or services of business users, the use of editors and their ability to influence the ranking of those goods or services, the amplitude of the impact of remuneration on ranking as well as elements that do not or only remotely relate to the good or service itself, such as presentational features of the online offer, could be examples of main parameters that, when included in a general description of the ranking mechanism in plain and intelligible language, should assist business users in obtaining the required adequate understanding of its functioning.
