The first draft should never be your final draft. So, while focusing on that, no matter how great a digital marketing agency you work at, or how good a copywriter you are, you are bound to miss out on technical details and make grammatical errors.
As a digital marketing service in Toronto, we cannot stress enough on the power of proof-reading.
Read, re-read, rewrite, delete and write it again, till you have the perfect draft, even though in social media marketing, no draft is perfect, but you can try to get close right?
