Statistical analysis of a landing-page test on 28,905 visitors, tested five ways to separate a real win from luck.
Highlights
Lift of +16.9% (p = 0.022), with a 98.9% probability that B is better
Showed the gain came entirely from mobile (+37%), while desktop was flat
Caught that the new page pushed buyers to a cheaper plan, so the revenue gain wasn’t proven
