It’s pretty standard advice. Word of mouth is critical to growing a successful product. Despite its importance, word of mouth has always been hard to measure and therefore hard to influence.
In 2014 I (Yousuf Bhaijee) worked at Zynga with Tomas Pueyo (author of coronavirus articles with 50M+ views) where we started looking at word of mouth acquisition. Through our journey, we created a simplified way of measuring word of mouth that was stable enough to use in forecasting and insightful enough that teams could figure out how to influence it. Since Zynga, I teamed up with Mike Taylor (co-founder at Ladder) to apply this method to products across a range of categories and have found it to be impactful for teams.
