Gut instinct has its place, but it should be the starting point of a decision, not the end of it. Data‑driven marketing replaces guesswork with evidence.
That means collecting the right signals, being honest about what they say, and having the discipline to kill campaigns that aren’t working — even the ones you love.
Brands that build a culture of measurement make better decisions faster, and they compound that advantage over every competitor still relying on opinion alone.
