A slogan is a brief, memorable phrase that is used to help people remember a product and encourage them to buy it. Slogans instantly communicate the nature of a business, product, or service in a way that appeals to the target audience. They are designed to be concise yet withstand the test of time across various forms of media. Effective slogans are appealing catchphrases like "Just Do It" or "Finger-Lickin' Good."
