When were the Barcelona Principles written?

The Barcelona Principles were established in 2010 as a set of guidelines aimed at improving the measurement and evaluation of public relations efforts. They emerged from a global summit in Barcelona, where PR professionals recognized the need for a standardized approach to evaluate the effectiveness of public relations campaigns beyond traditional metrics like advertising value equivalency (AVE). The principles emphasize the importance of outcomes over outputs, the necessity of measuring communication-related business outcomes, and the value of transparency and replicability in measurement practices. This framework has since been influential in driving the development of strategic measurement practices within the public relations industry.
