Overview
Most e-commerce projects worry about conversion. Wallpezia worries about something different, cost per visitor.
Wallpezia serves free licensed wallpapers, PNG images, videos and sounds. Users arrive, browse and download, and every one of those actions moves data. When the product is free and the traffic is large, delivery cost isn't an infrastructure detail, it's the business model. This isn't a store where a slow page costs a sale, it's a platform where an inefficient page costs money on every single visit, whether or not the visitor downloads anything.
