A decision tree is a visual tool that is used to help visualize and analyze the likely outcomes of complicated decisions, such as those faced when creating an advertising strategy for Facebook Advertising and Instagram Sponsorship. Essentially, it provides a framework for breaking down all of the various factors that could lead to success or failure in order to identify the best course of action. Creating a decision tree involves outlining each option and potential outcome, then systematically evaluating them in order to determine which choice will yield the best results.
