For each traction channel in your middle ring, now construct a cheap traction test you can run to determine if the idea really is good or not. These tests should be designed to roughly answer the following three questions: How much will it cost to acquire customers through this channel? How many customers are available through this channel? Are the

Making A/B testing a habit (even if you run just one test a week) will improve your efficiency in a traction channel by two or three times.
