Human choicebefore declaring a winner

The old way

Changing the headline is not a test until the traffic and conversion are measured.

Teams compare different weeks, channels, or gut reactions and call it evidence. A/B Lincoln assigns traffic consistently, tracks one chosen conversion, and explains what the current data actually supports.
