"Big data is important in marketing campaigns because of the insight it provides into the behavior and other personal aspects of your audience. When using it for storytelling in your campaign, you want to know what your audience cares about and how your brand or product relates to an emotional level. Let's say that you are marketing an accounting service for small business. You have collected a huge amount of data to understand the challenges and needs of people that would benefit from your services. The data shows a pattern of small businesses frequently switching accounting software. Digging further into the data, you find that a major frustration they are experiencing is finding a robust yet budget-friendly solution. Instead of just telling this group how your service compares and the price, you can evoke their emotions by telling a story of someone who was just like them and how your service solved their problem. The data has now allowed you to connect to the human side of your prospect in a way that posting product specs and pricing alone will not."
