The "copy" in this case means the words that a user will see when visiting a website or using a software application. A lot of people undervalue the work of a copywriter and usually opt to write their own content. However, a good copywriter can transform otherwise boring text into catchy and informative text that can have an immediate impact on the bottom line.
Unlike a technical writer whose work is intended to inform, a copywriter is striving to persuade. For example, a copywriter would write an ad designed to sell a big-screen TV, while a technical writer would write the operating manual to tell you how to use it.
