Retention refers to the ability to keep or hold on to something, such as customers or users, over a certain period of time. In marketing, it's about the strategies and tactics businesses use to encourage customers to continue using their product or service, rather than switching to a competitor. High customer retention means customers tend to stick with your product or service, which often translates to customer loyalty and higher profits.
