 Web 2.0 as a concept has become big in the Internet world, but this  phenomenon has yet to make large impact on conservative business segment  like e Commerce. Over the coming months this is going to change as more  and more online shopping sites are embracing Ajax based technology and  other Web 2.0 ideas. The originator of the Web 2.0 describes this term  to define new generation websites that use collective contribution,  social networking, tagging, open APIs, remix, etc. 
 Ajax, a short name for a combination of website developing technologies  and a key instrument of Web 2.0 concept, is used to create web  applications with enhanced usability, interactivity and speediness.  Present e Commerce sites are also in a position to reap similar benefits.
 Below are listed the primary reasons for visitors to abandon a shopping  cart and possible ways of dealing with it.
 1. Cost of shipping too high and not shown until checkout
 This seems to be the number one reason for most of the people to abandon  a shopping cart. The first step you need to take here has nothing to do  with technology. You have to understand that people are not willing to  pay extra on top of the real shipping and handling charge. People are  not stupid! They have more or less rough idea, how much shipping might  cost. That's why keep shipping and handling costs really low or at least  reasonable! The second step which can radically improve your conversion  rate is the use of new technology to keep the shopping cart with all  its content visible at the right upper side of the page presently  visited. Once a new item is added to the cart, all calculations will  take place right away without reloading the page or the cart. If you  feel that shipping and handling costs could be crucial in buying  decision, once the first item is added the system will ask for visitor's  zip code and automatically calculate the final price.
 2. Changed mind and discarded cart content
 In this case, unfortunately, you can't do much! However, if your site  automatically saves the content of the cart, there is a chance that the  same buyer might come back and continue shopping. Analysis of the exit  page of the visitor might also help you determine the reason why he or  she has left.
 3. Comparison shopping or browsing 
 Apart from monitoring your competitors' sites and keeping your offers  aggressive, you should also create a site with better functionalities  and contents than your competitors.
 4. Total cost of items is too high
 Again, if the cart is constantly visible with the final price always  calculated automatically, the buyer will be able to take a more  informative decision.
 5. Saving items for later purchase 
 The moment an item is added to the cart, it should be saved  automatically without reloading the page. If the buyer is not logged in,  upon exit request the buyer to register with just login and password,  explaining that this way she can come back and continue shopping on your  site.
 6. Checkout process is too long 
 If you have a shopping cart as described earlier all the buyer will need  to do is click to check out. A simple form with minimum information  needed to execute the check out process will appear upon checking out.  The filling out of this form should be the final step of the buying  process.
 7. Out of stock products at checkout time
 The functionalities of the cart, as described earlier, will let the  buyer immediately know whether the product is available.
 8. Checkout requires too much personal information 
 The Web 1.0 e Commerce sites collect a lot of information about the  customer, which presumably help get marketing data. These days, online  customers are not willing to reveal more than necessary information for  nothing. Avoid the temptation to ask questions unrelated to check out.  All you need is name, shipping and billing address and credit card  information. That's it!
 9. Poor site navigation and long download times 
 With the help of above mentioned technologies you will be able to  increase interactivity, speed and better navigation experience many  folds. 
 10. Lack of sufficient product or contact information
 Your contact telephone numbers should be always visible! Use A form or  wizard based product adding system. This will help you not to forget  crucial information related to an item when you add it to your database.  
 
 Of course there are other minor reasons why visitors abandon a shopping  cart, but if you make over your e Commerce site with the help Web 2.0  technologies many of these issues will also disappear.
