Overselling is a common practice used in marketing and sales, which involves exaggerating or misrepresenting the benefits or features of a product or service. Some synonyms for "overselling" include hype, exaggeration, hyperbole, inflation, overstatement, and embellishment. These terms all imply the same concept of going beyond the boundaries of truth and using clever marketing techniques to deceive or manipulate the consumer. Overselling can harm a company's reputation in the long term and can lead to lost customer loyalty and negative online reviews. Therefore, it is essential for businesses to avoid overselling and instead focus on providing accurate and honest information about their products or services.
