In e-commerce, an "abandoned cart" refers to the situation where a potential customer selects items for purchase, adds them to their online shopping cart, but then exits the website or app without completing the transaction. An abandoned cart represents an unfinished sales opportunity in the e-commerce context.Abandoned carts are a common occurrence in online shopping, and they can result from a variety of factors, including unexpected shipping costs, a lengthy or complicated checkout process, or distractions that lead the customer to leave the website or app before finalizing the purchase. E-commerce businesses often use strategies such as automated email reminders or improved user experience to encourage customers to return and complete their purchases, thereby reducing the number of abandoned carts and increasing conversion rates. Understanding the reasons for cart abandonment is essential for optimizing the e-commerce sales process and recovering potential revenue.
