Data has changed the evolution of design and marketing from its “traditional” version. Data was based on “focus groups,” where random individuals were questioned and observed. These meetings often produced subjective data results. Data makes the difference between success and failure for a marketing specialist, a designer or an expert in SEO. The implementation of an analytic code on a landing page or a pixel of Facebook, allows a designer to understand the behavior of the users within a web, their interests, their preferences, age, hours of the day they usually connect to the content, sex, purchasing level, color preferences, and many other categories. Therefore the data gives us the possibility to create the perfect elements for our users, and in turn receive the perfect interaction so that there is a system feedback.
