Information on ranking is without prejudice to Directive (EU) 2016/943 of the European Parliament and of the Council (345) on trade secrets. As explained in the parallel ranking transparency obligation for all online platforms and online search engines laid down in Article 5 of the P2B Regulation, this means that a consideration of the commercial interests of the relevant providers should never lead to a refusal to disclose the main parameters determining ranking. At the same time, neither Directive (EU) 2016/943 nor the P2B Regulation requires disclosure of the detailed functioning of the ranking mechanisms of the relevant providers, including their algorithms (346). The same approach applies to information requirement under the UCPD.
