As Peter Drucker famously wrote, “The aim of marketing is to know the customer so well the product or service fits them, and sells itself.”
In conversion optimization, we talk about the importance of knowing our customers a lot.
But we rarely talk about the process of strategically segmenting our audience so that our products and services can sell themselves.
You run an A/B test, and it’s a winner. Or maybe it’s flat (no difference in performance between variations). Does it mean that the treatments that you tested didn’t resonate with anyone? Probably not.
If you target all visitors with the A/B test, it merely reports overall results – and ignores what happens in a portion of your traffic, in segments.
