Concise Linking
Be sure to have a clear and concise order form available for the products on your website. Write a clear and concise message to direct the end user to your order form, so you will have minimal chance of losing the sale. Create a prominent link to your order page from every other page on your site.
Payment Options
Allowing the end user different payment options is a great way to earn trust. Some end users like certain payment options like PayPal while others may want to use their credit card or even a check. The more options you offer the end user the better your chances of making the sale.
Secured Encryption
Having numerous payment options is a good start but people also love to feel secure when it comes to their finances. Looking into SSL is one of the most cost-effective ways to help the end user feel confident in purchasing from your site. It is a great way to prove you are a credible merchant.
Customer Testimonials
Adding your contact information and customer testimonials is another great way to boost the end users confidence. Make them feel safe about purchasing your product. Remember you are a total stranger to them on the other side of the web.
Keep in mind that it would be horrible to put so much effort into making the sale to finally have it go awry in the end. Make sure to eliminate any possibilities of failure to maximize profit.
