Everyone has to start somewhere. But the first step is usually finding out what exactly it is that you don’t know. Start by learning the basics, either through self-study or a copywriting course. Then, practice, practice, practice. Write samples, start a blog, or offer to write for free for a local charity. Build a portfolio to showcase your skills, and then start applying for jobs or freelance gigs. (It’s as simple as that!)
And remember, every piece of copy you write makes you a more experienced copywriter than you were before. So get writing!
