The Guide on legitimate interests assessments (LIAs) under the GDPR is intended for companies engaged in digital advertising in the EU. It aims to provide a standardised approach to conducting an LIA that takes into account the particularities of processing and the associated risks in the industry.
The purpose of this document is to provide a practical guide to carrying out legitimate interests assessments (LIAs) in the context of processing data in ad tech, for digital advertising generally, and for RTB, in order to help companies understand their obligations, and how to comply with them in practice.
