How to monetize a free product with 1 million users?

Monetization of a free product with 1 million users can be achieved through several methods:

• Advertising. Embedding ads (banners, videos, native advertising). With a large user base, this can generate stable income.
• Premium features (Freemium). Offer basic functionality for free, and charge for additional features.
• Subscriptions. Regular payments for access to extended content or services.
• Partnership programs and affiliate marketing. Recommendations of products or services with a commission.
• Data sales (considering legislation and user consent). User behavior analytics for marketing purposes.

It is important to analyze user behavior and choose a model that does not degrade the user experience in order to retain and grow the audience.
