Answer:
The feedback from customers that helps to improve marketing tactics is typically called "customer feedback" or "voice of customer (VOC) feedback." This feedback can be obtained through a variety of methods, such as surveys, focus groups, social media monitoring, and customer reviews. Once collected, this data can be analyzed to identify areas for improvement in marketing tactics and to develop more effective marketing strategies. While Likert scales and surveys are commonly used methods for gathering customer feedback, they are just tools for collecting data and not specific terms used to refer to customer feedback in the context of marketing.
