What is Copywriting?
It's anything you need really. Do you require a few articles knocked together that will explain a product or service you provide? Perhaps you just need somebody to make the statistics and figures from your studies “live” a little better (instead of killing your audience with boredom). Perhaps you need a lengthy interview transcribed into an article that effortlessly flows like a conversation, or a mission statement that sounds poetic and inspiring instead of the rantings of a cold, greedy corporate type. A good copywriter has the power to make all of these things happen.
Language is a tricky thing in that some critical parts of your message can become lost or twisted with the wrong turn of phrase. Not to mention the minefield that is grammar and the language fascists who patrol the Internet nowadays. One wrong semi-colon or comma instead of an em dash and you'll have ze grammar gestapo on your case in no time.
