Personalization at Scale: Beyond Basic Dynamic Ads

Most so-called personalized advertising is a template with a variable in it. Real personalization changes the argument, not the noun: a different proof point, a different objection answered, a different pace of edit.

Generative systems make that economically possible for the first time. A single campaign spine can branch into dozens of genuinely distinct creative arguments, each aimed at an audience the data says will care.

The discipline is knowing where to stop. Beyond a certain granularity you are no longer personalizing — you are overfitting to noise.
