No. Review marketing every month, but judge each effort over a time frame that fits its job. Some work pays back fast. Some builds the demand you'll need next year. Agree on which is which before the results come in.
A monthly review can turn into a monthly squeeze if every dollar has to pay back by next month. That pushes teams toward whatever looks efficient this week and away from the work that helps customers pick you later.
In its summary of the 2026 report Go Big or Go Home, the IPA describes Binet and Davis's warning that chasing short-term efficiency too hard can hurt long-term growth and profit. [1]
Recent numbers aren't finished yet
Even fast-payback campaigns need time. Google explains that conversions can show up days after the click, so recent cost per acquisition can look too high and return on ad spend too low until the late conversions arrive. [2] Mark recent results as early, and say when they'll be ready to judge.
How I set it up
- Sort every effort by job. Capture demand now, or build demand for later.
- Give each one a time frame. Weeks for search ads. Quarters or longer for brand and new markets.
- Set learning milestones. First, do the right buyers understand the offer? Later, are qualified deals showing up?
- Agree up front. Write it down before launch, so nobody invents a new way to call it a win afterward.
That doesn't mean long-term work gets a pass. Track a few signals every month and say when each was last measured. And keep watching cash. Your CAC payback period, how long a customer's profit takes to cover what you spent to win them, has to fit where your company is today.
