Here are some of the key data pieces you really want to get right:
Product Title – Make sure that your product title gives shoppers a clear sense of what your product is. Include important keywords to help shoppers find what they are searching for.
Product Photos – Quality and quantity count. Your product photos should be large and high resolution so shoppers can zoom in if they want. White backgrounds are best, and include photographs from different angles.
Product Description – It’s important to include product specifications that shoppers are looking for, such as dimensions, weight, and materials. You also need to help them imagine using your product. Make sure your copy is easy to read – bold or italicize key words, use bullets, and keep your sentences short.
UPC/GTIN – Many online retailers require that you assign a Global Trade Item Number® (GTIN®) to your products and place a UPC barcode on your products. In fact, you should use the same GTIN online as you use for physical stores. Including a GTIN in your product listing helps search engines and consumers find your product easier, leading to more sales for you. Google reported that Merchants who’ve added correct GTINs to their product data have seen a 20% increase in clicks on average.
