To make a good sale you need to know your customer's habits. It may be a surprise to you that nowadays internet users are counting every split second they spend on their attention. From the moment they click a link or type a word in their favorite search engine, the clock is running. The eyes are looking, where is the next content for me? From the first sensorial perception to the visual cortex, it only takes 40 milliseconds for the brain to understand visual orientations, spatial frequencies, and colors. And then the customer wants more. Is she disappointed from waiting or is she excited to see the latest offers she is craving for?
