“Is marketing an art or a science?” I get asked this at conferences constantly.
My answer: It is both, and the ratio depends on what you are measuring.
The Case for Art
Some aspects of marketing are genuinely creative:
- Brand building: Emotional resonance cannot be A/B tested into existence
- Storytelling: Great narratives come from human insight, not algorithms
- Cultural moments: Timing and taste require intuition
- Creative execution: The difference between “good enough” and “iconic”
The best marketers I have worked with have genuine creative instincts that no amount of data can replicate.
The Case for Science
Other aspects are highly measurable:
- Media buying: Bid optimization, targeting, frequency capping
- Conversion rate optimization: Test, measure, iterate
- Channel allocation: ROI comparisons across touchpoints
- Pricing: Elasticity can be measured experimentally
Here, rigor beats intuition. The data is clear, and disciplined testing wins.
Where It Gets Complicated
Most marketing lives in the messy middle:
- A brilliant creative idea and smart media placement
- Emotional brand messaging and conversion-optimized landing pages
- Intuitive campaign timing and rigorous post-analysis
The best marketing organizations do not choose between art and science—they integrate them.
Implications for Measurement
This matters because you cannot measure art the same way you measure science.
Trying to prove ROI on brand-building with the same rigor as performance marketing leads to:
- Underinvestment in brand (because it is hard to measure)
- Over-optimization for short-term metrics
- Commodity creative (because “data-driven” beats “inspired”)
Instead:
- Measure what can be measured rigorously
- Use proxies and judgment for what cannot
- Do not let measurability drive strategy—I think this is where many data teams go wrong
My Working Framework
| Marketing Activity | Art/Science Mix | Measurement Approach |
|---|---|---|
| Brand campaigns | 70/30 Art | Brand tracking, long-term lift |
| Content marketing | 60/40 Art | Engagement, assisted conversions |
| Performance marketing | 30/70 Science | Direct attribution, ROAS |
| Pricing/Offers | 20/80 Science | A/B testing, elasticity |
The Bottom Line
The art vs. science debate is a false dichotomy. Great marketing requires both.
The analyst is job is not to eliminate art with data—it is to help the organization make better decisions by being clear about what we know, what we do not know, and what we are betting on.
Sometimes that means running rigorous experiments. Sometimes it means trusting the creative instincts of talented marketers.
The wisdom is knowing when to do which.
