Why do shoppers leave the checkout before making a purchase? More importantly, what can you do about it?
People abandon shopping carts for many reasons. Some simply change their minds or are just “window shopping.” You don’t have much control over those instances. Some, however, find the checkout process confusing or aren’t sure what you're going to charge their credit cards. You do have control over these issues.
With the current state of the economy, you can’t afford to lose a single sale because your shopping cart doesn’t function the way shoppers expect. Here are eight leading ways to decrease shopping cart abandonment — simple, practical things you can do to make sure your cart meets best practice standards:
1. Make sure your “add to cart” button is above the fold on all product detail pages. Don’t forget to test it on different screen sizes and resolutions — not everyone has a large monitor. Don’t let your “add to cart” button disappear on smaller or laptop screens.
2. Label the cart button “add to cart.” Don’t label it “buy,” “purchase” or any other creative name. “Buy,” or similar language, leaves shoppers wondering if they can keep shopping or change their minds, triggering a host of psychological barriers to purchasing.
3. Once shoppers have filled their carts, make sure your checkout button is easy to find. Again, don’t get creative with naming it. Call it “checkout” or “proceed to checkout.”
4. Show item descriptions and images on your cart pages. Shoppers need to be clear about what they're buying; images with text clarify it for them.
5. Make sure your customer service number is prominently located in the header of all your pages. This helps increase trust and may salvage a sale if a shopper is confused.
6. Show the shipping calculation added to the cart total before you ask for credit card information. If visitors are unsure of what they’ll be charged, they won’t give you this information.
7. Don’t empty visitors’ carts when they leave your site. Make it convenient; use cookies to save their carts so they won’t have to re-browse and re-add everything when they come back.
8. Test, test and test again. Make small, incremental changes and measure their success. Best practices will take you a long way, but nothing beats knowing what works for your shoppers.
Following these guidelines will help decrease shopping cart abandonment on your e-commerce site. Competition for shoppers’ dollars is higher than ever, and you can’t afford to lose a single sale. You’ve devoted so much to getting shoppers to your site; don’t lose them this late in the game.

Some really great points Terry. Shopping cart abandonment is an increasing headache for most the online retailers and it is not that easy to decrease as it might look, even if it sounds pretty simple. I am a strong believer that the simpler the overall process the more effective it will be and we shouldn't "overload" our buyers with too much information
Loved the article and then followed the link to the other Ability Commerce white papers. Mostly stuff I knew, but the current screen resolution numbers on browser usage was extremely helpful with our new site redesign.
Great way to draw traffic into the site but there really isn't anything new to learn from this post. I'd like to see some data to back up your claims as well. Things which interest me are multi-page check vs. single page, A/B testing with different page elements and copy, etc. I mean this as constructive criticism, mind you, not trying to be a d-bag. ;-)
Interesting article. I stumbled upon this blog post that adds more insight into shopping cart abandonment and how to reduce it: http://lunchpail.knotice.com/2008/07/23/5-mistakes-that-promote-cart-abandonment/
