Loren Tomlinson presented on the top 5 mistakes businesses make with their digital marketing. The mistakes are: 1) Lacking goals and strategy which provides no direction or way to measure progress. 2) Having no social media presence despite most of the world's population using social media. 3) Neglecting to build and nurture audience relationships through email communication. 4) Taking too broad of an approach to advertising without targeting the right audience. 5) Not using an omni-channel approach across multiple platforms to maximize reach. The key takeaways are to strategize for success, embrace social media, nurture relationships, advertise precisely, and use an omni-channel strategy.
