@Traumflug, I assume he's speaking about a similar format to amazon.com, walmart.com, or patagonia.com, which have separate pages. In their case, since they are multi-line retailers with thousands of different products, I see the appeal. It presents another opportunity to cross-sell. I assume they're doing it because data supports that they sell significantly more when structured that way. For companies that don't have a lot of cross-sold product opportunities, it probably doesn't make as much of an impact.
