The document discusses the evolution of marketing from Marketing 1.0 to Marketing 3.0. Marketing 1.0 was product-centric, while Marketing 2.0 became consumer-centric. Marketing 3.0 focuses on meeting consumers' emotional and rational needs by prioritizing engagement, collaboration, and building brand credibility through trust, authenticity and transparency. Some marketers still rely on outdated metrics like impressions and reach, but Marketing 3.0 requires understanding social media influencers and adapting to the increased power of consumers online.
