Bol.com: Product Page — Bigger Add-To-Cart Button
After detecting some success with a more padded button, Bol continued their a/b test iteration. The Dutch online retailer ran an experiment with an even wider add-to-cart button on their product pages.
Hypothesis
If we test a similar change on our product pages as Bol.com rejected, we should be cautious — their rejection suggests it underperformed.
