The sites are slow, terribly optimized for mobile, and possibly the worst for search engines. On top of that, don't spend too much time designing your site or editing it, because at least once a week, Wix's design tools won't allow you to save all your work. 4 hours down the drain each week, at least! If you have a real business, stay away from Wix! You're much better off spending a little more money with Squarespace, Setmysite, or some kind of actual website solution. Wix is nothing but a toy... a very poorly designed toy.
