Shopping Cart Usability
Usable Shopping Carts Increase Sales 
E-commerce has been around since 1993 under many different names,  but one thing remains constant; shoppers want usable web sites.  Without a usable shopping cart the sites typically fail from poor  performance. To succeed in the world of e-commerce and on the  Internet web sites must be developed to be usable by patrons as  well as search engines.  
The most successful sites have been turning to web analytic  software to tell them how people use their site. When they notice  a break in their site they go in to determine the problem.  Marketers tend to think the words on the site are the breaking  points; while this may, in part be true, it is more often how the  site operates and makes shopping easier for the customer.  
Elements of a Usable Shopping Cart 
Before a usable shopping cart can be developed several elements  must be realized and controlled. Not all things can be overcome,  but all things can be controlled. Understanding human nature and  how people use new tools can help in controlling the most  challenging situations.  
Site Navigation 
Site navigation must be as easy as possible. Without making the  navigation as easy as possible customers will become confused and  frustrated which encourages them to leave without purchasing.  
Breadcrumbs 
Breadcrumbs are the links found in web sites that show the  hierarchical path of the page. Not everyone enters a site through  the front page and breadcrumbs make it much easier to reach  related products without having to dig around the site.   
Adding Items to the Cart 
Shoppers want to see some visual confirmation that the action  they take works. Sites that fail to provide visual cues lose  customers due to confusion and the thought that the site doesn't  work.  
JavaScript 
JavaScript requires the browser to support JavaScript. Without  the ability to support JavaScript or with JavaScript turned off,  functions that require JavaScript can't work. Vital shopping cart  functions should not be developed in such a way that JavaScript  is required.  
Flash 
Flash requires the shopper to support the version of Flash being  used. People that support Flash 4 can't support Flash MX without  upgrading. Customers will leave for another store if they are  required to upgrade their plug-ins. At the very least, it will  require that they have to download the plug-in and start the  shopping experience from the very beginning.  
Checkout Process 
The checkout process should be as short as possible. The faster a  person can checkout the faster the customer can be on their way  to other things.   
Checkout Progress 
Each step of the checkout progress should indicate the current  step and the total number of steps. This helps the customer know  where they are in the process and the number of steps remaining.  
Ask for Information in the Proper Order 
Credit card information should never be asked for until after all  the charges have been calculated and presented to the customer.  Asking for this information prior to disclosing the full charges  will cause the shopper to abandon the cart.  
Advantages of Usable Shopping Carts 
Usable shopping carts open the market to the consumer.  By making  a shopping cart usable to the consumer the process of shopping  online is less threatening and actually becomes more inviting.   NetIQ, the developers of WebTrends, has developed a successful  system that helps web site owners, marketing specialists and web  development teams make more usable and helpful web sites.  
Understanding how shoppers use one's site and shopping cart can  help turn more visitors into purchasing customers.  The national  average for shopping cart conversion is two percent; however that  conversion rate can be increased through having more usable web  sites and shopping carts.  Multiple paths to the products and  easier checkout processes can help greatly.
