Why a higher TV CPA can be more PROFITABLE than a low Meta CPA

Acquiring a client for €10 on Facebook or €25 on TV: which holds more economic value for your company? The answer is mathematical and will shake up your performance reports.

< p > This is a conversation we frequently have at Jour de Chance during campaign debriefs with scale - up Chief Marketing Officers.

"Our direct CPA (Cost Per Acquisition) from our Billboard or TV campaign came back at €40, while our Meta algorithm on Lookalike audiences still manages to get clients at €15. Why should we keep investing in these overpriced mass media?"

Looking coldly at the dashboard, the question is legitimate. But it hides a fundamental analytical error regarding two metrics: Incremental Volume and, above all, LTV (LifeTime Value).

The Illusion of the Algorithm's "Floor CPA"

Platforms like Google Pmax and Meta Advantage+ are incredible precision machines. They are designed to target "Low-Hanging Fruit": people who were about to buy anyway. They cannibalize the Bottom of the Funnel.

The problem with this €15 CPA is that it is infusional and not scalable. If you double your Meta budget from €50k to €100k, the algorithm will saturate. Your CPA won't stay at €15; it will explode to €30 or €40 because it will have to seek out increasingly less qualified audiences (the Scale-up Gap).

Mass Media Brings "The Unknown Client"

TV, Catch-up (CTV), and DOOH (Digital Billboard) impose the message. They don't seek someone "in-market" with purchase intent. They create the initial need.

Result: the apparent direct CPA is systematically higher. (Ex: €40 vs €15). BUT this €40 client is pure: they would never have bought without that TV spot.

LTV (LifeTime Value): The Ultimate Judge

This is where post-TV cohort analysis becomes fascinating. Deep analysis of our Fintech subscriptions (like Exploris or Deblock) often reveals the following:

📉
The "Facebook Acquisition" Cohort (€15 Client): These are often clients hunting for promo codes, impulse buyers, or highly volatile individuals. Churn is high from the second month. One-year LTV: €60. Estimated Profit: €45.
📈
The "Brand/TV Acquisition" Cohort (€40 Client): TV establishes deep statutory trust. The client was convinced by the credibility and "brand safety" of this massive medium. This client opens their banking app more often, buys higher-tier baskets (upsell), and stays subscribed longer. They naturally act as advocates (Lower churn). One-year LTV: €150. Estimated Profit: €110.

The Real Metric: The LTV/CAC Ratio

- Digital Performance Ratio: €60 / €15 = x4
- Brand/TV Ratio: €150 / €40 = x3.75

The ratios are almost identical in pure profitability. But the big difference? The TV ratio is highly scalable to break your business stagnation, right where the Meta volume was capped very low.

Stop Optimizing CPA at the Expense of Volume and Quality

Asking a marketing director to steer their budget at a "Constant CPA" is stifling the startup's growth. A higher CPA isn't a failure; it's the normal "prospecting tax" you have to pay in the "Upper Funnel" to locate highly valuable, loyal client reserves. An agile media mix balances both to drive the startup's direct Profit, not the conversion cost.
