Viral growth occurs when users have such a great experience that they recommend your service to others, leading to organic growth without additional costs.

If your product is social in nature, having more users improves the experience, making it essential to focus on virality and referrals.

A simple and easy-to-use product encourages user retention and can lead to viral growth.

To achieve virality, your product must inherently encourage sharing from day one, rather than treating sharing as an afterthought.

Virality occurs when one user introduces your product to others, while network effects mean the product becomes more valuable as more users join. Successful consumer companies leverage both to grow their user base organically.

Referrals amplify word of mouth; offering financial incentives for users to share your product can enhance this effect.

Word-of-mouth growth is the most effective form of marketing; create a compelling story about your product that users want to share.

To enhance virality, identify sharable moments in your product where users are inclined to share their achievements, like completing a level in a game or achieving a milestone.

The secret to virality is that there is no such thing as a truly viral product. It's about word of mouth, where one user spontaneously tells another about your product, which has shaped much of what we do at Superhuman.
