When conducting marketing surveys, if you want to design questions to favor a certain product or service, you can guide the respondents' opinions in the following ways: 1. **Use leading questions**: When designing questions, you can use suggestive language to make respondents tend to give positive feedback. For example, "Do you think our products are better than competitors in terms of quality and price?" This type of question implies the advantages of the product being investigated. 2. **Provide limited choices**: In multiple-choice questions, the options given to respondents can only include options with positive evaluations, or put a certain product at the top. This can increase the possibility of the option being selected. 3. **Use situational description**: Describe the product or service by providing a positive situation so that the respondents can evaluate it in a positive situation. For example: "Imagine that your life will become more convenient and efficient after using our new product. Are you satisfied with this?" 4. **Emphasis on product advantages**: Highlight the advantages of the product or service in the question. For example, "Do you agree that our service has always been among the best in customer satisfaction?" This way of expression may affect the respondents' cognition. 5. **Avoid negative statements**: Avoid using negative words in questions and ensure that the questions are constructed in a positive way to avoid triggering any dissatisfaction with the product or service. For example, don’t ask “What are you dissatisfied with about our product?” 6. **Sequence effect**: In a survey, you can choose to ask positive questions related to the target product first to subtly influence the respondents’ subsequent answers. For example, first ask about their satisfaction with a certain service, and then ask them about their willingness to purchase the service. 7. **Use background information**: Before the survey begins, provide positive background information or publicity about the product so that the respondents form a positive impression in their minds, thereby influencing their answers. It should be pointed out that although the above methods can influence the opinions of respondents in the short term, this practice may affect the credibility and validity of the survey results, and may also damage the brand image in the long run. Therefore, when conducting marketing surveys, it is usually a more important strategy to remain fair and objective.
