Convincing shoppers to buy when the economy is shaky is harder than in times of boom. Your best bet is to double down on your core hero products. These products are the ones your customers love and why your brand exists. But even still, not just any marketing will do. Creating a marketing strategy around user-generated content can help you connect with your customers and inspire them to buy those hero products. And authentic content from your fans is your fuel for e-commerce growth.
