People will spend both money and time on your website if it is easy to use and navigate.
 Don't ask the customer to provide too much information about themselves or they will bail out before buying.

 Offer a money-back "no questions asked" guarantee and promote it.

 Provide free information and samples to entice your customers to buy.

 Let people know you accept many forms of payment-checks, credit cards, faxed orders, phone calls or e-mail.

 Offer sales support after someone buys your product. Invite them to call or e-mail you if they have questions.

 Use a shopping cart program so customers can add and remove items from their shopping cart before they "check out."
