In online advertising, there are some common methods to exaggerate the effects of products and mislead consumers to buy. Here are some of the main methods: 1. **Exaggerated advertising**: Using absolute terms such as "immediate results" and "unparalleled" to give consumers the impression that the product is extremely effective. 2. **Pseudoscience**: Quoting unverified scientific terms or studies, or using scientific data out of context to support the promotion of product effects. 3. **Celebrity endorsements**: Using celebrity or expert endorsements to enhance the credibility of products, even though these endorsers may not have relevant expertise. 4. **Fake reviews**: Creating a good reputation through fake reviews, fake user feedback or manipulated ratings, thereby misleading potential consumers. 5. **Comparison advertising**: Making a product appear more advantageous by selectively showing the comparison between the product and its competitors, while ignoring other important information or comparison aspects. 6. **Using "performance guarantees"**: Promising a refund or performance guarantee, but hiding harsh conditions or restrictions, so that consumers mistakenly believe that the product is risk-free. 7. **Emotional marketing**: Using consumers’ emotional needs, such as anxiety, hope, etc., to drive consumption decisions rather than based on actual product quality. 8. **Ambiguous terminology**: Using vague or ambiguous terms to make it difficult for consumers to accurately understand the true effects or ingredients of the product. 9. **Color and image processing**: Making products look better than they actually are by over-beautifying product images or using unrealistic visual effects. 10. **Limited time promotion**: Creating a sense of urgency, claiming that the product is limited in quantity or the price is about to increase, prompting consumers to make impulse purchases without sufficient consideration. These tactics may affect consumers’ judgment and lead to wrong purchasing decisions. When shopping, consumers should be vigilant and conduct sufficient research and comparisons to obtain real information.
