When ads feel expensive, ask what the customer is worth
“Our ads are too expensive.”
I hear that sentence often. Sometimes it is true. Often it is incomplete.
Expensive compared with what? Last month’s CPC? A competitor’s anecdote? A target that was set before anyone modeled contribution margin? A feeling that the click price has climbed while revenue has not explained itself yet?
Cost only becomes meaningful beside value. Until then, “expensive” is a mood, not a diagnosis.
CPC is not the decision
Cost per click and cost per thousand impressions are useful operating metrics. They are poor substitutes for commercial judgment.
A $0.40 click can be disastrous if the traffic never converts, never retains, and never produces margin. A $8 click can be a bargain if it reliably creates customers whose contribution pays back quickly and compounds over time.
The platform will always make the cheaper click look attractive. The business has to ask whether the cheaper click is the better customer.
This is the first reframe I want founders to keep: high media costs do not automatically mean the channel is broken, and low media costs do not automatically mean the channel is working.
Expense thinking versus investment thinking
If advertising is treated only as an expense, the goal becomes minimization. Cut CPC. Cut CPM. Cut the budget when finance gets nervous.
If advertising is treated as an investment in acquiring customers, the goal becomes return under constraints. What is a customer worth? How long until cash comes back? What is the risk of under-investing while competitors keep learning?
Those are different meetings.
Expense thinking asks, “How do we spend less?”
Investment thinking asks, “What are we willing to pay for a customer we understand, and what evidence do we need before we pay it?”
I am not arguing for reckless spend. Weak economics are still weak economics. A high CPC does not excuse a broken offer, a confused ICP, or a landing page that leaks trust. Investment framing makes those problems clearer, not easier to hide.
The cost of not investing
There is also a quiet cost that rarely appears in the ad account: the cost of not acquiring the right customers while the market is available.
That cost might be slower learning. It might be a sales team with too little pipeline. It might be a competitor who becomes the default because they stayed present while you optimized yourself into invisibility.
This does not mean every channel deserves more money. It means “pause” and “cut” should be decisions about expected value, not only reactions to rising unit costs.
A useful question in a tense budget review: If we cut this spend by 40%, what customer value do we believe we are giving up, and how sure are we?
If nobody can answer, the team is managing discomfort rather than managing growth.
A simple value check
Before declaring ads expensive, walk through a plain sequence:
- What is average order value, or average initial contract value?
- What contribution margin remains after COGS and variable delivery costs?
- What retention or expansion can you defensibly expect, not hope for?
- What CAC would still leave an acceptable payback period for your cash position?
- What is the current blended CAC, and what is the marginal CAC of the next dollar?
That fifth item matters. Blended averages can hide the fact that the next dollar is already buying weaker inventory.
Suppose a business clears $80 in contribution from a first purchase after COGS and variable delivery costs. Cohort evidence from recent acquisitions shows that 40% of those customers place a second order within six months, and that second order contributes another $60 on average. Expected six-month contribution is therefore:
$80 + (0.40 × $60) = $104
That longer view is useful. Cash still sets the near-term limit. Finance needs payback inside roughly 60 days to keep working capital comfortable, and inside that window almost all of the observed value is still the first order. The team also wants about $20 of contribution left after CAC as a cash buffer. Under those constraints, allowable CAC is:
$80 − $20 = $60
Now the CPC debate becomes a math problem. A $25 CAC pays back on the first order and leaves $55. It sits well under the $60 ceiling, so it can be rational even if the click feels expensive in the auction. A $90 CAC exceeds first-order contribution by $10 before any repeat arrives. Even though six-month expected contribution is $104, the cash position cannot fund that delay. The creative can be excellent and the CPC can look “normal” for the category. The acquisition is still too expensive relative to what the customer is worth on the timetable that matters.
The ad did not become expensive because the auction moved. It became expensive because customer value and acquisition cost fell out of relationship.
Agency and operator decisions should start from value
This is also how I think about value-based partnership decisions.
If an agency or internal team is optimizing for cheaper clicks without a shared model of customer worth, they will eventually optimize the account away from the business. If they ignore media efficiency entirely and talk only in abstractions about brand, they will lose the right to manage real budgets.
The useful middle is commercially rigorous and still human: understand the customer, understand the economics, then decide what attention is worth.
That standard applies whether spend is $10,000 or several million a month. The numbers change. The question does not.
Are your ads expensive, or have you not yet defined what a customer is worth with enough honesty to judge them?
