The Pricing Headline That Won Clicks and Lost Revenue

Headline A: "Simple, transparent pricing." Headline B: "Pay only for what you use."

I tested both over 30 days and 22,000 visitors. Headline A won click-through to signup: 14.2% vs 11.8%. I shipped A.

Three months later I checked revenue per visitor. Headline B had produced 22% higher revenue per visitor. It attracted fewer people, but they chose higher tiers and churned less. I optimized for the wrong metric at the start.

Has anyone else had a conversion winner that lost on revenue?
