Writing a product copy that sells is both an art and a science. It’s an art because it requires expertise, creative skills, and know-how. Having all these elements enables you to craft a copy that not only educates your prospects but also persuades them to make a purchase. It is also a science because your copy will go through a slew of trials, tests, failures, and subsequent improvements. By maintaining the right balance of both, you can come up with a killer product copy.
