The document discusses various ways to measure and evaluate the success of public relations campaigns. It emphasizes that defining specific, measurable goals upfront is important so success can be determined based on whether those goals were achieved. It then provides many examples of metrics that can be used, such as increases in sales, media impressions, audience awareness, and audience actions like purchases or information requests. It also discusses tools for tracking traditional media clips, online mentions, and website traffic.
