Abstract: The object of this research is the public relations in the area of functionality of the trade aggregators online. The subject of this research is the normative legal acts regulating these public relations. A definition is provided to the trade aggregators, with emphasis on the key disadvantages of e-commerce for consumers from the perspective of application of such tools. The author examines foreign experience of legislative regulation of e-commerce, as well as underlines one of the crucial problems in regulation of e-commerce relations consisting in responsibility for the quality of information, published by the seller within the framework of indicated aggregators. As evidenced by practice, online purchase of goods involves various risks and conflict situations, which should be taken into account by all e-commerce participants. It is noted that the activity of aggregators intensify competition in e-commerce. Thus, the author suggest to enshrine a universal definition of Internet aggregators not in the sectoral legislation, but in Law No. 149-FZ of July 27, 2006  “On Information, Information Technologies and Information Protection". Only then would be possible to establish responsibility of the trade aggregators in sectoral legislation (for example, in the area of transportation services, communications, commerce, etc.).
