👉 Overlisting is a term used in marketing and advertising to describe when an item or product has been added to multiple lists, such as Facebook's "likes" list. This can happen for various reasons, including an accidental addition of the item to another list, a typo, or simply because it was already on the page. Overlisting can affect the visibility of the item in search results and can result in a decrease in sales or other negative impacts on the brand.
