Internet marketing is a complex and rapidly changing field, with new vendors popping up all the time. How can you know if a particular Internet site is genuine? What will it be like trying to shop on this site? Is your financial information safe? Will your purchases actually arrive, and will they be on time? What if the item is broken, or if you just don’t like it? Can you return it? Our database contains articles that review Internet marketing sites from Amazon to Zazzle. Comparison-shop across websites. Read reviews that describe their quality and security, as well as the shopping experience. If you are a vendor who wants to sell your wares through third-party websites, see what sorts of services they offer and how many shoppers use them. Make sure you like their policies, and check for hidden fees like extra shipping and handling, cash transfer or “convenience fees.”
