We remember things better when we have experienced them through multiple senses.
Our memory is used to experiences containing information through multiple senses, because that's what happens in the real world. Sadly, as a website owner you can only use a very small subset of senses. Smell, touch, taste, temperature etc. don't go through an internet connection very well, so you have to make sure you dó use the ones that are available: sight and hearing (and some might add humor). Add images, audio and video to let people experience your products and to augment the claims you make in product descriptions.
