This document discusses using web analytics in public relations. It begins by explaining how measuring audiences has changed online compared to traditional media, as online audiences are defined more by individual behavior and attitudes rather than demographics. It then discusses how the traditional advertising model of separate media companies has broken down online as barriers to entry are lower and all companies compete directly with each other. The document emphasizes that what really matters online is what people do and think rather than just who they are. It provides examples of useful metrics for public relations professionals like visits per unique visitor and page views per visit, compared to meaningless "famous" metrics like total pageviews.
