Hi Romario -

Thanks for your comment! To answer your questions:

There are no silver bullets in marketing or customer experience, and that's true for all brands. Any shopping experience is a complex system of interconnected, behavioral science and psychological principles.

However, there are certain principles that seem to punch above their weight when it comes to impact. Creating simple experiences and managing for choice overload are two of those.

No brand, however strong, will convert over the long-term if the psychology of the shopping experience - including how many products are displayed - isn't right.
