Monetization models refer to the strategies businesses use to generate revenue from their products or services. Common models include subscription fees, where customers pay regularly for access, and advertising, where companies earn money by displaying ads to users. Other models include pay-per-use, where customers pay based on their consumption, and freemium, which offers basic services for free while charging for premium features. These models can vary widely depending on the industry and target audience. For example, software companies often use subscription models, while social media platforms may rely heavily on advertising. Understanding these models helps businesses choose the best approach for profitability.
