copywriter = someone who writes the words for advertisements
Longman Dictionary of Contemporary English
Sometimes the meaning is extended to "writing any kind of commercial texts" and even to writing texts in general. The latter is a mistake.

is it a kind of translation?
how can i get some information and some specific examples about it?
