Change Your Sales Page Based on Their Beliefs and Assumptions
If you know your target audience, you might also know the general list of their beliefs and prior assumptions. It would be useful to learn the exact ones for each visitor.
When a visitor comes to your sales page, immediately show them a pop-up with a list of these beliefs and assumptions, and ask them to choose the ones they identify the most with. Based on their answer you then display slightly different sales page – emphasizing the relevant sections to address these – to each visitor.
