A content audit is a comprehensive evaluation of the content of a product or service. It is a useful tool for identifying issues and opportunities for improvement in the content.  To conduct a content audit, designers should start by gathering a complete list of all of the content on the product or service, including text, images, videos, and any other media. They should then evaluate each piece of content based on factors such as relevance, accuracy, and usability.  Based on the audit, designers can identify any issues or problems with the content and make recommendations for improvement. The audit should include both qualitative and quantitative data and should be based on user-centric design principles.
