"Best Selling" refers to products or items that achieve high sales volumes within a specific time frame. This term is commonly used in various industries, including books, music, and consumer goods. A product is often labeled as "best-selling" when it ranks among the top sellers in its category, indicating popularity and consumer demand. In the publishing world, for example, a best-selling book is one that has sold a significant number of copies, often appearing on lists like the New York Times Best Sellers. These rankings can influence consumer choices, as many people tend to gravitate towards products that are already popular among others.
