11. Unprofessional appearance
“Your book is an excellent example of gateway science fiction, and I’ve persuaded my mother-in-law, who thinks SF is juvenile, to give it a shot. However, when she goes to your site, she’s confronted with a jumbled assortment of star backgrounds, laser-gun clip art, and photos of your pets. She concludes that she was right; this is not the site of a professional anything.”
You need honest critiques of your website just as you do for your fiction. Ask a few people who don’t live with you to give you their reactions to your new designs.
