Online shoppers don't get to see, touch, feel or smell your product so the next best thing is a crisp, clear product image. While you shouldn't entirely cut corners on photography, you don't have to hire a professional to get high-quality images. But you should use "a 16-megapixel DSLR camera, decent lighting, and a lightbox.
A photo lightbox is a tent-like container with several light bulbs aimed at its interior that photography professionals often use to create well-illuminated images of objects.
Writing for product descriptions should be short, yet rich with enough interesting details to pique customer interest. Always try to use compelling adjectives and phrases that evoke an emotion when someone reads your description, without getting too carried away or taking up too much space.
In addition to noting the price, you may want to include product uses, dimensions, and other defining characteristics.
