As a marketer trying to sell something, making people think ahead and then back gives them a new perspective that can help you both.
While visiting you website, at some point after they had time and already consumed at least the main points you want to convey about what you are selling, they are already dealing with a decision – to do what you ask them or not, to buy or not – you can ask the following question: “many years from now, when you look back, what would you regret more, saying yes now or saying no?” Measure the conversion rate when using this question and compare to the conversion rate when not using it.
