Why it works
The story is tight and specific: one test, one metric, one clearly explained mechanism. The analytical section explaining why 'Buy Tax-Free' outperformed 'Shop Online' gives readers a transferable copywriting lesson, not just a result. The 99% statistical confidence detail adds credibility to the headline number.
Steal this
The post-result 'why did this work' breakdown ties the outcome to named behavioral and copywriting principles, turning a single A/B result into a reusable mental model for readers.
