Double Your Money Back If This Doesn't Work. No Questions Asked. No Fine Print. Just Return It.

RMBC Breakdown

Why this copy works — broken down by Research, Mechanism, Brief, and Copy layer.

R — Research

Research insight: Halbert's testing revealed that 'double your money back' outperformed standard money-back guarantees by 2-3x in conversion, while actual refund rates increased by less than 10%. The math is counterintuitive: a bolder guarantee generates far more incremental sales than it costs in additional refunds. The buyer interprets the bold guarantee as extreme confidence in the product.

R — Research

Research insight: Research shows that longer guarantee periods actually decrease refund rates. A 30-day guarantee creates urgency to evaluate and potentially return. A 365-day guarantee removes urgency entirely — the buyer forgets about the return window and keeps the product. Meanwhile, the long window dramatically increases conversions because the buyer feels zero time pressure to decide.

R — Research

Research insight: B2B buyers are more risk-averse than B2C buyers because purchasing decisions affect their career. Performance-based guarantees outperform money-back guarantees in B2B by 2-4x because they address the real fear: 'If this doesn't work, I look bad to my boss.' The metric-specific guarantee ('your [specific metric] doesn't improve') shifts the burden of proof to the seller, which is exactly what the buyer's procurement process demands.
