Often, it isn't enough to just have a gleaming picture of your product above its name. How can customers use the product? Why will they benefit? Who is this product for? What material is the product made of?
A product description answers these questions, puts customers in the mindset of using the product and, ideally, leads to a sale. The description should truly be useful, simple and enjoyable. Nothing turns a customer off more than fluff and generic terms such as "very," so specific language, bullet points, images and a clever title can be the difference in a customer buying from you versus going elsewhere.
