Why it works
The case study earns credibility by narrating a failed first test before the successful second one, which makes the result feel earned rather than cherry-picked. The mechanism is explained clearly enough to replicate: test placement and design affected banner blindness, and fixing that drove the lift. The story sits between Breakthrough and Efficiency, but the headline leads with revenue going up, so Breakthrough wins the tie-break.
Steal this
Include the failed first test before the successful one. Showing a wrong turn and the reasoning for continuing makes the final result more believable and the methodology more instructive.
