Analyzing and using customer reviews is made easier by tagging, a method of assigning keywords or codes to these reviews. By associating a customer review with a specific product, specific topics such as delivery, usage, or customer service, or even a store number, it becomes easy to extract reviews matching a given tag. This greatly simplifies marketing analysis by grouping reviews according to predefined criteria. Furthermore, tags can be used to filter reviews displayed on specific pages of a website based on particular domains. Review tagging can be done before publication using tools integrated into the review platform, or afterward through automated semantic analysis or manual processing during moderation.
