Neuromarketing: applications and current state in Spain.

Neuromarketing is the discipline that applies cognitive neuroscience methods to the study of consumer behaviour. It does not replace traditional marketing or qualitative research: it complements them by recording what the customer cannot or will not verbalise. According to the Neuromarketing Science & Business Association (NMSBA), the sector generated USD 4.3 billion in 2024 globally, with a projection of USD 6.7 billion by 2027.

The figure matters because it marks a turning point: neuromarketing has stopped being an academic curiosity and has become an operational tool for major advertisers. Nestlé, Mercedes-Benz, BBVA, Mercadona and most streaming platforms use it to validate campaigns, packaging and digital experience before launch. In Spain, according to the IAB Spain barometer 2024, 18% of the top-100 advertisers declare they have used at least one neuro technique in the past twelve months.

What is neuromarketing and how does it relate to neuroscience?

Neuromarketing was born at the border of three disciplines: consumer psychology (which has existed since Ernest Dichter in the 1950s), behavioural economics (Kahneman, Tversky, Thaler) and cognitive neuroscience with brain-imaging techniques. The term was coined by Ale Smidts, professor at Erasmus University, in 2002. The field consolidated academically with the first international conference in Houston in 2004 and operationally with the founding of the NMSBA in 2012.

The technical difference with classical market research lies in the source of the data. A focus group records what the person says; a neuromarketing technique records what the body does while the person perceives a stimulus: pupil dilation, facial micro-expression, skin conductance, gaze path, brain activity. These data are useful because, as Daniel Kahneman showed in Thinking, Fast and Slow (2011, Nobel Prize 2002), the brain makes around 95% of its consumption decisions in automatic mode (what he calls System 1) and only 5% in deliberative mode. The customer is not lying in the focus group: they simply do not have conscious access to 95% of what they are deciding.

What neuromarketing techniques are actually used?

There is a real distance between the techniques that appear in popular books and those used in agencies and consultancies. The table below reflects real usage in 2025 according to the NMSBA annual report:

Technique	What it measures	Avg session cost	Real usage (2025)
Eye-tracking	Visual path and attention	€2,500-6,000	68% of projects
Facial coding	Emotional micro-expressions	€1,800-4,500	54%
GSR / EDA	Emotional arousal (skin conductance)	€2,000-4,000	41%
EEG	Attention, engagement, memory	€8,000-22,000	27%
fMRI	Deep brain activation	€40,000-120,000	3% (large projects only)

The operational reality is that 80% of commercial neuromarketing projects combine eye-tracking, facial coding and GSR. The three techniques are non-invasive, mobile, quick to deploy (sessions of 90-120 minutes with 25-40 participants) and allow three key variables to be triangulated: where the customer looks, what emotion they feel and with what intensity they respond physiologically.

EEG (electroencephalography) comes in when temporal engagement or memorisation needs to be measured — it is the preferred technique for evaluating audiovisual spots. fMRI (functional magnetic resonance imaging) is reserved for academic research or for very large advertisers with budgets over €100,000 per study.

What concrete business problems is neuromarketing used for?

The six most common use cases in commercial projects 2024-2026:

1. Packaging validation. Before printing 200,000 units of a new pack, an eye-tracking session with 30 participants confirms whether the key elements (logo, claim, benefit) are the first things the eye finds on a simulated shelf. Average saving: 1.8% of launch investments that pass conventional testing but fail on shelf.
2. Evaluation of spots and branded content before air date. EEG identifies the exact seconds of attention loss. In a 30-second spot, the first critical second is usually 7-8 (when the viewer decides whether to skip) and 22-24 (logo entry). Brands with neuromarketing optimise those points.
3. A/B tests for landing pages and emails. Eye-tracking over version A and version B reveals patterns that aggregate clicks do not show: where the gaze gets stuck, which CTA goes unnoticed, which copy generates reactance.
4. Physical store design. Customer path, friction points and emotional response to signage and promotions. Retail is the second-largest client of neuromarketing in Spain according to IAB Spain (2024).
5. Pricing. How the customer reacts to price depending on how it is presented (decoy effect, anchoring, digit format). Neuromarketing provides behavioural evidence for pricing hypotheses.
6. Digital experience. Apps, e-commerce, product configurators. Cognitive friction is measured in fixation time and negative emotional arousal.

What does neuromarketing do and what does it not do? The ethical and technical boundary

Neuromarketing does not read minds. It does not identify political preferences, intimate opinions or individual purchase intentions. What it does, in technical terms, is compare the average response of a group of participants to stimulus A versus stimulus B and return a statistical differential. It is advanced market research, not mind reading.

"Neuromarketing is not a trick to sell more by force. It is a microscope to understand why some messages work and others don't. The difference between ethical selling and manipulation is not in the technique; it is in the intention of whoever uses it."

— Patrick Renvoisé, The Persuasion Code (Wiley, 2018)

The NMSBA has had a code of ethics since 2013 with five mandatory principles for its members: informed consent, anonymity, no research on minors without a guardian, no research that may induce psychological harm, methodological transparency. In Spain, all serious consultancies also comply with the GDPR (Spanish: RGPD) regarding the collection and storage of biometric data.

What neuromarketing should not do and does not do in serious projects:

• Identify individual participants by their brain pattern.
• Diagnose mental illness or clinical tendencies.
• Modify the behaviour of people without their knowledge.
• Apply techniques to vulnerable populations (minors, people with cognitive disabilities).

How much does a neuromarketing project cost and when is it worth it?

The range is wide. A pilot eye-tracking session over a single stimulus (an ad, a piece of packaging, a landing) costs between €2,500 and €5,500 in specialist Spanish agencies, with report delivery in two to three weeks. A full project with triangulation of three techniques, 30-40 participants and comparison of several variants is between €9,000 and €18,000.

The profitability criterion I apply in consulting is simple: the cost of the study must be lower than 1.5% of the total cost of the decision being made with it. If a company is going to invest €600,000 in an audiovisual campaign, a €6,000 study (1%) to validate the piece is more than justified. If it is going to invest €12,000 in a local micro-campaign, neuromarketing doesn't fit: doing the study costs more than the risk of being wrong.

SMEs can access simplified versions: online simulated eye-tracking tools (Predict, EyeQuant, Attention Insight) based on neural networks trained on hundreds of thousands of real data points. They do not substitute laboratory eye-tracking but they are useful for validating digital mock-ups for under €200 per month.

What relevant neuromarketing cases have been documented in Spain?

Some publicly known examples:

• Estrella Galicia (2019-2024). Submitted several generations of packaging from its 1906 range to eye-tracking and facial-coding sessions before each relaunch. The documented result: labels with fewer textual elements and stronger visual hierarchy increased choice rate against competitors on a simulated shelf by between 12% and 18%.
• BBVA (Aprendemos Juntos campaign). The pre-launch test included EEG to optimise the duration of the pieces. The data led to fixing the optimal duration for long formats at 12-18 minutes, not the 5-7 dictated by industry convention.
• El Corte Inglés (retail floor redesign, 2022-2023). Mobile eye-tracking path studies in the Madrid flagship led to reorganising category layout in four of its main sections. Documented improvement in conversion rate per visit: +9.3%.
• Mercadona (limited public disclosure). Since 2018 the chain has used an internal testing lab with in-store customer observation and prototypes. It is not strict academic neuromarketing but shares the methodology.

How do you train in neuromarketing and what do professionals earn?

Formal training in Spain follows three paths:

1. Specialist master's. ESIC's Neuromarketing master's (Madrid, Valencia, Barcelona), the UCM master's in Consumer Psychology Research, and the Universidad Camilo José Cela programme in partnership with Bitbrain (Zaragoza, EEG hardware specialists). Cost between €6,500 and €14,000.
2. NMSBA certification. Four certification levels (Foundation, Practitioner, Advanced, Professional) recognised internationally. Cost €1,500-4,800 depending on level. No prior degree required.
3. In-house training at agencies. Large consultancies (Nielsen, Kantar, Bitbrain, Sociograph, BrainSigns) offer onboarding programmes for junior profiles. They typically hire psychologists, neuroscientists or statisticians.

The average salary of a junior neuromarketing researcher in Spain in 2024 is between €26,000 and €34,000 gross per year (Hays and Michael Page data). A senior with five to eight years of experience reaches €50,000-68,000. The most in-demand profiles combine training in psychology or neuroscience with statistical skills (R, Python) and experience with specific software (Tobii, iMotions, Affectiva).

How does neuromarketing integrate with overall strategy and the rest of marketing?

The most common mistake I see in consulting is treating neuromarketing as an isolated tactical tool: "let's do an eye-tracking on the website". That framing wastes 70% of the value. Neuromarketing pays off when it is integrated into a broader decision-making process:

• Before: a clear strategic hypothesis — emerges from the work of redefinition in strategic marketing and from the answer to Levitt's question about what business the company is really in.
• During: the neuro technique that suits the question (not the fashionable technique).
• After: interpretation that closes the loop with the marketing plan and the commercial plan — not a report that gets filed in a drawer.

A company that applies neuromarketing without having resolved its market definition first optimises the communication of the wrong message. One that applies it afterwards and well multiplies the return on every euro spent on communication.

What role do AI and predictive models play in 2026 neuromarketing?

The most relevant change of the last three years has been the incorporation of predictive models trained on huge datasets of real neuro responses. Tools such as Predict by Neurons (Copenhagen), EyeQuant (Berlin) or Attention Insight (Vilnius) offer synthetic attention maps generated by AI with measured correlation of 0.82-0.89 against real eye-tracking maps. The difference: they cost between €100 and €600 per month instead of €4,000-8,000 per study.

The operational impact is clear. For low-to-medium criticality decisions (any landing, banner, email, social post), predictive AI is already good enough. For high-criticality decisions (audiovisual campaign with investment over €200,000, core product packaging, flagship retail redesign) the physical lab is still needed.

The boundary between the two methods narrows every year. The NMSBA estimates that by 2028 between 70% and 80% of neuro projects will be hybrid (AI + physical lab) and only 15-20% purely physical. Consultancies that don't incorporate AI will be priced out of the SME market.

How to start using neuromarketing in a Spanish SME without spending thousands of euros?

Three accessible and proven steps:

1. Audit the website with a synthetic eye-tracking tool. Attention Insight, Predict and EyeQuant have a free trial plan. One hour of work is enough to identify the main attention problems on the home page, the main landing pages and the checkout.
2. Validate the packaging or main creative of the year in a pilot session. Spanish consultancies (Sociograph in Madrid, Bitbrain in Zaragoza, Goli in Barcelona) offer pilot sessions between €2,500 and €4,000 with 20-25 participants. A single well-designed pilot produces data for three to six months of decisions.
3. Include emotional-response questions in post-purchase surveys. It isn't neuromarketing in the strict sense but it uses its conceptual framework: measuring emotional intensity (1-9 scale), valence (positive/negative) and associated words. Cross-analysis with NPS and repurchase usually surfaces patterns that NPS alone doesn't show.

Neuromarketing as a discipline reached its operational maturity recently. Today it is one more tool in the strategic marketing toolbox, not a technological novelty. The right question is not "should we do neuromarketing?" but "what marketing decisions are we taking with incomplete information that could benefit from additional behavioural evidence?"

If you are considering integrating it in your next annual planning and want to review where it pays off most per euro invested in your specific case, book an initial session at no cost and we'll design a realistic protocol for your company together.

Frequently asked questions

What is neuromarketing?

A discipline that applies neuroscience methods (electroencephalography, eye tracking, skin conductance, fMRI) to the study of consumer behaviour. It measures what people cannot or do not want to verbalise in a survey.

Where is neuromarketing applied?

Mainly in four areas: packaging optimisation (what attracts the gaze), digital UX (what frustrates the user), pricing (what price generates unconscious resistance) and advertising effectiveness (which moment of the ad hooks the viewer).

What methods does neuromarketing use?

The most common are eye tracking (measuring where the eye looks), EEG (brain activity), GSR (skin conductance as an indicator of emotional arousal), facial coding (micro-expressions) and, in extreme cases, fMRI.

When does it make sense to invest in neuromarketing?

When the cost of being wrong is high and traditional surveys don't resolve the doubt: packaging launch, e-commerce redesign with high traffic, SaaS pricing decision or securing the effectiveness of a high-investment advertising campaign.
