My take-away from the report is pretty clear: Retail Web sites don't need superfluous bells and whistles that just make them perform slowly or that impede navigation. Users want to log in, find what they need via a decent search tool and reasonable product images, toss that stuff in the cart, see what the total price will be -- with taxes and shipping -- before entering their credit card and shipping information, then quickly and securely pay and go.
If you want me to spend extra time registering and logging in before you let me make a purchase, you'd best give me some incentive; I have enough login names and passwords as it is. How about you prove to me that your site truly is worth using and that you'll complete my order to my satisfaction before making me decide that I want to be a repeat customer and set up an account?
We've looked at this question before, but what has frustrated you most when shopping online? Or, what do you like best about your online-shopping destinations of choice?
