What is viral lift?

Viral lift refers to the increase in user acquisition or engagement that occurs when existing users promote a product or service to new potential users, often through Word-of-mouth or sharing on social media. This phenomenon can create exponential growth, as each new user may further share the product with others. Viral lift is a key metric for evaluating the effectiveness of marketing campaigns, particularly in digital platforms. Ultimately, it highlights the power of network effects in driving user growth.
