Relevant Signatories will further develop and apply policies, features, or programs across Member States and EU languages to help users benefit from the context and insights provided by independent fact-checkers or authoritative sources, for instance by means of labels, such as labels indicating fact-checker ratings, notices to users who try to share or previously shared the rated content, information panels, or by acting upon content notified by fact-checkers that violate their policies.

Relevant Signatories will report on the policies, features, or programs they deploy to meet this Measure and on their availability across Member States.

Relevant Signatories will report through meaningful metrics on actions taken under Measure 21.1, at the Member State level. At the minimum, the metrics will include: total impressions of fact-checks; ratio of impressions of fact-checks to original impressions of the fact-checked content–or if these are not pertinent to the implementation of fact-checking on their services, other equally pertinent metrics and an explanation of why those are more adequate.

When cooperating with independent fact-checkers to label content on their services, Relevant Signatories will report on actions taken at the Member State level and their impact, via metrics, of: number of articles published by independent fact-checkers; number of labels applied to content, such as on the basis of such articles; meaningful metrics on the impact of actions taken under Measure 21.1.1 such as the impact of said measures on user interactions with, or user re-shares of, content fact-checked as false or misleading.
