There might be hundreds of websites selling the same product that you are selling. Why would customers buy from you? What is so special about your product or your service? You need to be different from your competitors, you need to be unique.
Your unique selling point can be:
Your price.
Your customer service.
Your niche.
Your transport cost.
Extra detailed product description.
Return policy.
Exclusive products.
Your websites.
Whatever you think, make sure you make above things to be clear to your customers when they visit your site.
