When designing marketing survey questions, if the purpose is to favor a certain product or service, the following strategies can be adopted, but it should be noted that this practice may cause the survey results to lose fairness and reliability: 1. **Use leading language**: Use positive adjectives or favorable descriptive language in the questions. For example, "How was your experience using our famously efficient friend app?" Such questions imply that the app has been widely recognized. 2. **Comparative questions**: Highlight your own products by implying the disadvantages of other products. For example, "Do you prefer our smooth and fast app to other slower apps on the market?" 3. **Selective question setting**: Only ask questions that help to draw positive conclusions and ignore questions that may reveal weaknesses. For example, ask "What features of our product do you like most?" instead of asking "What do you think is the room for improvement in our product?" 4. **Exclude negative options**: Do not provide negative options in multiple-choice questions, or reduce the proportion of negative options. For example, the options are mostly positive and neutral, and only one negative option is provided. 5. **Pre-introduction**: Add positive information or success stories before the question to make the respondents have a positive impression of the product. For example, "Many users have reported that our product is easy to use. Please rate your experience." It should be noted that although these strategies may help obtain seemingly favorable survey results in the short term, they may damage the brand's reputation in the long run. Honest and fair survey results can effectively guide product improvements and market strategies.
