Thanks for commenting on the post. :)

To take another contrasting opinion. Who cares if you know exactly why you're going. We know in a general sense why we're growing: we constantly improve the experience of our service and make customers happier.

It's quite hard to maintain aggressive year over year growth targets. If you're pulling it off it really doesn't matter if you figured out why via a/b testing or not.

Obviously, we'd prefer stronger YOY growth without knowing the exact causes than weaker YOY growth because we wasted resources on a/b testing to get precise answers to why we're succeeding.

Beyond that, I wasn't referring to trending growth via GA to see if you're making good decisions. You can trend conversion rate by channel to see if you're getting better over time. Obviously, if conversion is going up and to the right for most channels you're making good decisions.
