Sometimes less is more in e-commerce and digital marketing. ✅
Additive Bias makes us want to add features, but in e-commerce, more features often mean more clutter. We ran a "Subtraction Test" to see if removing elements could actually boost sales.
We removed a complex Estimated Delivery timeline from a mobile product page. The element used exact calendar dates (Dec 16–18) rather than simple text, creating high cognitive load.
🏁 The Results:
➡️ Conversion Rate: +13.55% (6.14% → 6.97%)
➡️ Revenue per Visitor: +11.98% (34.07 → 38.15 CZK)
What did we learn?
The timeline was friction. It forced customers to "do the math" on logistics instead of focusing on the product. On mobile, reducing cognitive load is a direct path to higher conversions.
— One test result is worth a thousand expert opinions.
