Why it works
The story earns its Breakthrough tag because the headline leads with a number going up, but the Clarity element is strong too: the team genuinely did not know whether a widely accepted best practice applied to their context. The $10,000 weekly incremental sales figure grounds the percentage in real stakes. The mechanism is specific enough to replicate: a split URL test on 8,000 visitors comparing login page variants.
