First, timing is huge. Everything, ultimately, comes down to being able to increase the size of your media buys when response rates (CVR, click through rate, etc.) are high and media costs are low. Essentially, a low buy-in with a high projected reward means it’s time to throw your budget behind the opportunity. Conversely, knowing when to “take cover” — to scale down spending when response rates are low and media costs are super competitive — is the other part of the timing puzzle on which profits hinge.
