Why it works
The case study is specific about the mechanism: a font size increase from 15px to 20px and a bold weight change on the sale price were the only variables tested, making the result easy to understand and replicate. The dual metrics (36.54% Add to Cart lift and 10.21% revenue increase) give readers two reference points for evaluating impact. The story is thin on customer voice and the statistical significance caveat on revenue is buried rather than addressed directly.
