Bounce Rate

a subset of churn (retention) - % of users who don't use your product in month2. See (2020-07-21) Libin Presents His Model to Answer All Startup Growth Questions.

• Libin's take: if your bounce rate is over 30%, that's your top priority to fix
• a corollary: if your bounce rate is over 30%, you don't have product-market fit. (cf the very-disappointed test)
