This diagnostic uses three warning signs to detect a measurement trap. The first is an excessive preference for the most direct attribution, which biases investment toward people already near conversion. The second is a demand for discrete, non-overlapping channel measurement, which ignores the compounding effects produced when awareness, content, search, and direct response reinforce one another. The third is a steadily rising cost per conversion or equivalent acquisition metric, suggesting that spending has become too concentrated in easy-to-measure placements and is exhausting available demand. When these signals appear together, leaders should examine a broader advertising portfolio, measure incrementality, and test whether marketing is expanding the serviceable market rather than merely extracting more value from existing prospects.
Origin
Extracted from Marketing Against The Grain after the hosts used Nike's reported performance-marketing shift to identify practical measurement warning signs.
Core principles
- 01Measurement precision is not the same as business effectiveness.
- 02Channel overlap can compound growth rather than contaminate attribution.
- 03Rising conversion costs can reveal excessive dependence on harvestable demand.
- 04Easy-to-measure activity should not automatically outrank effective activity.
How to run it
- 1
Audit the Attribution Preference
Review funding and reporting decisions for an automatic preference toward activity with the most direct measurement.
Pro tip Compare how often leaders ask whether a channel is effective versus whether it is attributable.
Watch out Direct measurement can still be useful; the warning is treating it as the sole criterion.
- 2
Inspect Channel Overlap
Identify whether reporting attempts to isolate every channel and remove all overlapping influence. Look for complementary paths that collectively move customers.
Pro tip Map common journeys involving awareness, search, organic visits, and retargeting.
Watch out Do not double-count revenue simply because overlap can be beneficial.
- 3
Plot Conversion Costs
Chart cost per conversion or the relevant acquisition metric over time and against increasing spend.
Pro tip Use marginal cost curves rather than a single blended snapshot.
Watch out Temporary cost increases may come from seasonality or auctions rather than structural saturation.
- 4
Evaluate Market Expansion
Check whether current marketing increases awareness and demand among new audiences or merely serves known prospects.
Pro tip Pair the audit with an incrementality study or audience-growth measure.
Watch out A strong short-term ROAS does not prove that the serviceable market is growing.
- 5
Rebalance Toward Effectiveness
Redirect part of an overconcentrated budget toward validated incremental and brand activity while preserving efficient direct response.
Pro tip Make controlled reallocations and measure total business outcomes.
Watch out Do not respond by abandoning performance marketing entirely.
In the wild
A retailer reports precise channel-level ROAS but repeatedly removes campaigns whose effects overlap with search. Meanwhile, its cost per conversion rises each quarter and most spending targets previous visitors. Applying the checklist reveals all three warning signs and prompts tests of broader video and awareness activity.
→ The retailer recognizes that attribution cleanliness has become a substitute for market growth.
Common mistakes
Equating Precision With Truth
A precisely calculated metric can still represent only a narrow part of the growth system.
Treating Overlap as Waste
Multiple channels can reinforce one another and create compounding effects even when attribution becomes less discrete.
Ignoring Marginal Cost Trends
A favorable historical average can hide rapidly worsening returns on each additional unit of spend.
Is it for you?
Best for
It is best for founders, CFOs, and marketing leaders auditing a performance-heavy advertising portfolio.
Not ideal for
It is not ideal as a standalone causal analysis because each warning sign still requires investigation and testing.
From the transcript
“One, you care about the most direct measurement, two, you care about discrete measurement.”
“The universe compounds. That overlap is magical. That overlap is what gives you growth and what gives you a flywheel of customers.”
“If you're advertising your cost per conversion or your cost per whatever metric you're measuring, if that keeps going up, you're invested too densely in…”
