ROPO, also known as Research Online, Purchase Offline, is a consumer behavior where individuals conduct research and gather information about a product or service online, but ultimately make their purchase in a physical store. This trend has become increasingly prevalent in the age of e-commerce, as consumers seek to balance the convenience of online shopping with the tactile experience of in-store browsing. ROPO is a crucial factor for businesses to consider in their marketing strategies, as it highlights the importance of a strong online presence and the impact it can have on offline sales.
