Magicians are skilled manipulators of perception. They can make people think something is moving when it isn’t or see things that aren’t there. Diverting attention this way and that, they can hide cards and rabbits or make objects appear from thing air.
Sales copy is a little like that, depending on who writes it. Diverting attention with a little smoke and mirrors often draws readers inwards towards a sale. It’s persuasive copy, written to get people believing in the buy.
