What is your offer? Product/Service? Do you have a sales funnel?
Keep on generating traffic and if you have an enticing offer, I'm sure you will start to see the sales roll in. Here is a great article detailing all the ways that you will create organic traffic to your offer: http://marketinghangout.co/u/1620/17-ways-to-improve-website-traffic. I hope you can use some of the strategies in the article to keep bringing people to your offer and convert into some sales!
Could you give more details about your website/business? What do you sell (if anything)? Who do you target? You need to provide much more information before anyone can help you here.
Anyway, if you are in the business of selling stuff and aren't seeing any sales then you need to look at the payment methods you offer (again, if any). Is it just cards? PayPal? You may want to consider getting a payment provider/merchant account handler to help you with this - Paymentwall, G2A Pay and Braintree are just some of the options out there.
As I say though, it depends what business you're in.
