When it comes to marketing, a fundamental rule to follow is do not promote all your products or your entire store, instead, concentrate on promoting a select few products that have higher chances of selling. You might have hundreds of products in your store, but not all products will sell equally well. Some sell more than the others. You should promote products that are selling. Since these items are already successful, they can yield substantial profits with a little bit of marketing effort. You can also create a product bundle to sell other products along with winning products. For instance, if your shoes are selling well, offer socks as a combo and add a discount.
