How to Grow Growth Products

Time spent, by the way, is a metric that a lot of organizations do use. But it's not a growth metric usually. Retention means users come and use your product again and again and again. The higher this line is, probably the better product market fit you have. So retention is really key. And once you understand retention, you can start analyze retention. You can see how retention is being affected by different features on your product. Or by different user characteristics. For Facebook for example, if you're talking about what’s my retention for 60 days, 90 days, half a year? Okay. If you have a year retention, you're in a good place.
