Here is a senario:-
Shopping online, you have found the perfect designer wallpaper in a St Louis based store, time to checkout..but where is the checkout button..on the top, on the side where? This is a site where the checkout button is not intuatively postioned.
Don’t make me think!
As a site visitor you are being asked to do too much visual processsing to complete your order.
Good web design is all about producing an interface which interacts with the site visitor in an intuative way. In an e-commerce site excellent and easy to use navigation is crucial. The bad positioning of a checkout button can mean a shopping cart is abandoned and a sale is lost.
