(2011-10-03) Cohen Focus One Metric

Noah Kagan taught Jason Cohen to Fo Cus on 1 (AARRR) Metric and ignore everything else. He chose to focus on signups.

I Commented that it seemed like this was based on the belief that 1 metric was easier to make a big improvement on than the others. In this case it seems reasonable, since I could easily get sign-ups to double if I just spent 5 times as much on AdWords. On the other hand, for startups with LTV under $1500 that model might not be a plus for profitability/sustainability. He responded: No, a change from 3% to 1.5% wouldn't have been enough because that doesn't (for example) double the amount of revenue we get in a month, which is far more valuable.

Oct17 update: but he's not ready to ignore his cancellation-rate (retention). He helps measure/predict it more accurately than some simple models, and shows how it ties into Life Time Value (LTV).
