There are plenty of theories about why certain sales copy turns readers into customers. Each piece of copy has the same objective but will go about it in a different way. I feel that every piece of copy also has one main selling point. Whether it's a low price, the novelty or exclusivity of a product or the ability to receive said product immediately, there is always one thing which tips the scales and makes the reader buy what you are selling.
I would love to hear what you guys think is the most important factor in the buying decision. What do you think is the last piece of the puzzle, the last bit of weight that tips those scales? If your reader is on the fence, what pushes them over to the other side?
I look forward to the responses, discussions on this sub-forum are always quite lively.
