With every piece of marketing content you put into the world, you have the opportunity to learn more about your audience and the resonance of that content. Each like (or lack thereof), good comment (or bad), you’re learning more about what content is engaging your audience most. Within the reactions is all the data needed to create more personalized content. And that is no longer a “nice to have.” Personalized content delivered in the moment, and driven by specific needs of your audience is a requirement for formative engagement.
