Selpway Trading specialists advise: before you start advertising to attract customers to your online shop, you should check whether the website is working efficiently enough. If it does not work properly, your entire marketing budget, efforts and time will be wasted. First of all, the site should not have any technical problems, as this will negatively affect its promotion and reputation among customers. In addition, the website of your online shop should be convenient, understandable and useful for the user.
