Unfortunately, lots of websites may not be considered usable and push off lots of potential customers just because it's hard to find a menu, or a product price list, or to navigate through different sections. These looking little gaps sometimes turn out to be really critical, especially for small businesses, and have no right to remain unfixed. It's great if you have worked hard on functionality, but what's the use of it if no one will like to work with the site because it's inconvenient or ugly? Any web project has to be well optimized for search engines and on the other hand it has to be very simple to navigate, clear and easy to use.
