This report presents the assessment of the implementation of the Alliance to better protect minors online (‘the Alliance’) through an independent study. Officially launched in February 2017, the Alliance is a multi-stakeholder platform through which Member companies make a series of commitments to address emerging risks that minors face online. The initiative focuses on protection from harmful content, conduct and contact, and seeks to identify possible areas within these three categories that would benefit from a coordinated approach from companies and other stakeholders to overcome them. The study assesses the strengths and weaknesses of the Alliance in its first 18 months of operation, as well as its relevance, effectiveness, impact, coherence, and EU added value. This assessment is based on evidence collected via a self-assessment questionnaire filled out by Alliance Member companies, interviews with Alliance Member companies and Associate Members, and other stakeholders, desk-based work, and workshops held with Members and Associate Members. Furthermore, the report collates examples of good practices among Alliance Member companies in addressing the risks minors face online and provides recommendations for the future orientation of the platform
