Examples of online intermediation services covered by this Regulation should consequently include online e-commerce market places, including collaborative ones on which business users are active, online software applications services, such as application stores, and online social media services, irrespective of the technology used to provide such services. In this sense, online intermediation services could also be provided by means of voice assistant technology. It should also not be relevant whether those transactions between business users and consumers involve any monetary payment or whether they are concluded in part offline. However, this Regulation should not apply to peer-to-peer online intermediation services without the presence of business users, pure business-to-business online intermediation services which are not offered to consumers, online advertising tools and online advertising exchanges which are not provided with the aim of facilitating the initiation of direct transactions and which do not involve a contractual relationship with consumers. For the same reason, search engine optimisation software services as well as services which revolve around advertising-blocking software should not be covered by this Regulation. Technological functionalities and interfaces that merely connect hardware and applications should not be covered by this Regulation, as they normally do not fulfil the requirements for online intermediation services. However, such functionalities or interfaces can be directly connected or ancillary to certain online intermediation services and where this is the case, the relevant providers of online intermediation services should be subject to transparency requirements related to differentiated treatment based on these functionalities and interfaces. This Regulation should also not apply to online payment services, since they do not themselves meet the applicable requirements but are rather inherently auxiliary to the transaction for the supply of goods and services to the consumers concerned.
