The mechanics of a referral program should be clear and enticing. For example, offering rewards for both the referrer and the new user can incentivize sharing.

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

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

Viral growth requires not just a good product but also an excellent user experience that encourages users to share it with others. A strong referral program is essential for facilitating this growth.

Incentives can be a scalable growth tactic if implemented correctly, such as through referral programs that leverage existing users to attract new ones.

We implemented a referral program that incentivized users to invite others, which significantly contributed to our growth by leveraging shared folders.

Making it easy for people to share your product increases the likelihood they'll do it; providing sample tweets or posts can significantly boost engagement.

Referrals can be a powerful growth strategy, but they should be measured for incrementality to ensure they are effective and not just perceived as free growth.

The network effect is crucial in marketing; products that improve as more people use them create a compelling reason for others to join in and spread the word.
