Excerpt

Word-of-Mouth & Virality Framework

A framework for engineering word-of-mouth and making products, ideas, and content contagious, based on Jonah Berger's research into why things catch on. Use it to design shareability into products, campaigns, and content instead of hoping for luck.

Core Principle

Virality is not born — it is engineered. Products spread because they were designed — consciously or not — to be shared. Only 7% of word-of-mouth happens online; the other 93% happens in offline conversations, so virality is about the psychology of sharing, not social media mechanics. Those psychological patterns are predictable and can be engineered into anything using the STEPPS framework.

This is the opening of the README. Read the full README on GitHub.
