Here are the top four mistakes I see independent authors making that are absolutely certain to drive away potential readers. #1 Mentioning you checked spelling and grammar in your book description or on social media. I am genuinely shocked at the number of times “authors” tout this as a reason to buy their book. It takes MINUTES to run spell check in a word processing program. You do not get a gold star or a pat on the head for doing this. Adults are expected to do this.
