The best eCommerce content builds connections between your customers and your products. For best results, avoid being salesy and instead build a genuine connection. Try telling the story behind your products and your brand.  User-generated content is always good too. After a sale, ask your customers to send images and videos of themselves using your product. You can offer a discount to incentivize this. Then you can take the quotes and testimonials and use them as further social proof on your website.
