Taking advantage of consumers' misunderstanding of advertising information to increase sales is an unethical behavior that may damage the brand's reputation and should not be encouraged or adopted. Integrity is the cornerstone of business operations. Although misleading consumers may bring a certain sales growth in the short term, in the long run it will cause consumer dissatisfaction, loss of trust, and negative word-of-mouth communication, causing great harm to the brand and is not conducive to the sustainable development of the enterprise. The correct advertising strategy should be based on the true, accurate and clear communication of the value, characteristics, advantages and other information of the product or service, and guide consumption in a positive way by establishing good communication and trust with consumers, so as to achieve reasonable sales growth and healthy development of the brand. Only by adhering to the principle of integrity can we win the long-term support of consumers and the recognition of the market.
