CSAT is short for Customer Satisfaction Score. CSAT is a common customer experience metric that measures happiness with a product, service, or support interaction through a brief customer survey that asks, “How satisfied were you with xyz?”. Customers respond using a 1-5 scale, ranking from Extremely Dissatisfied to Extremely Satisfied. The survey is commonly presented as a traditional questionnaire, popup or persistent form on your website, inside an app, or by SMS.
