The Barcelona Declaration outlines 7 principles for effective public relations measurement:
1. Goals should be quantitative and address who, what, when and how PR will affect stakeholders. Measurement should include traditional, social and digital media as well as changes in awareness, attitudes, and behaviors.
2. Measuring outcomes like brand awareness is preferred to just measuring outputs like media clips. Quantitative surveys should track changes from PR activities.
3. Where possible, the effect on business results like sales should be measured using models accounting for PR and other factors.
4. Media measurement of traditional and online coverage should consider audience, tone, credibility and message delivery rather than just volume.
5. Advertising value equivalents do not value
