The document discusses three common digital marketing flaws that can negatively impact a brand online: 1) having a disconnected story across platforms by only publishing videos to YouTube without connecting them to the brand's main website, 2) treating social media as just another publishing channel rather than engaging with audiences, and 3) thinking of mobile experiences as separate from other digital experiences instead of providing consistent branding across devices. It provides examples of how to avoid these flaws by adding annotations and descriptions to videos, tailoring social media content to different networks and audiences, and designing for consistent experiences across devices. The key is to focus on building trust, personalization, authenticity, connection, and consistency for digital audiences.
