Metrics that are not relevant for the development of the digital product or service, nor do they provide valuable information for making business decisions. The number of visits to a website, the number of followers on Twitter , the number of fans on Facebook can be interpreted as vain indicators. They are easy to measure or monitor, but their usefulness is limited and they can give a false idea of growth. They are different from actionable metrics.
