Understanding consumer psychology is the difference between digital advertising that converts and ads that get ignored. In this expert mentorship led by Jonathan Zamacona, director of the School of Marketing at Platzi, you learn how the human brain drives purchase decisions and how to connect with your digital consumer through neuromarketing. This is for marketers, entrepreneurs, and anyone building a brand online.

Here is the tension worth remembering: 85% of your customer's decisions are unconscious, and only 15% are conscious. If you design your advertising for the 15% and ignore the 85%, you are leaving most of your persuasion on the table.

Why does understanding your consumer's brain matter for advertising?

Jonathan explains that knowing your customer demographically is not enough [09:00]. Knowing whether they are a man or woman, their age, their country, or the browser they use tells you very little about why they actually buy.

We search, compare, and decide, mostly without realizing it. When we need something, we look it up, compare it against competitors, check recommendations, and only then make a decision. The catch is that most of that process happens beneath our awareness.

What percentage of purchase decisions are unconscious? According to the data Jonathan shares, 85% of digital consumer decisions are unconscious and only 15% are conscious. Most buyers believe they chose freely, but an unconscious factor drove the purchase.

How does the triune brain theory explain buying behavior?

Jonathan builds everything on the triune brain theory by Paul MacLean, which divides the human brain into three regions [12:00].

• The reptilian brain is the oldest and most developed part. It controls survival, metabolism, and sexual reproduction. It is the part that reacts first to an earthquake alert or a fire alarm because it keeps you alive.
• The limbic system sits in the center and holds the amygdala. This is where your emotions live, and it is the unconscious part that controls most of your buying actions.
• The neocortex is the most advanced region, the front part that separates us from primates. It handles reason, logic, and conscious thought.

Of the three, the limbic system is the one to master if you want to understand the digital consumer from a neuroscience perspective.

What is the amygdala's role in buying decisions? The amygdala is a small almond-shaped region deep in the brain's central area. It drives your emotional state when you decide whether to buy a product or service.

What are the 7 tips to improve digital advertising with psychology?

Jonathan shares seven practical recommendations grounded in neuromarketing, plus a bonus tip on calls to action [21:00].

How do emotions and scarcity influence digital consumers?

The first tip is to lead with emotions, because so many actions are unconscious and driven by the limbic system. Coca-Cola, a brand over 100 years old, evokes emotion through friendship, romance, family, and even pets. Their personalized-name campaign is the clearest example: people did not buy the product to drink it, they bought it to feel the sensation of holding a can with their own name.

The second tip is to appeal to the reptilian brain, the selfish, self-focused part. Speak to the consumer in the singular, not the plural. The classic "I need you" military recruitment poster works because it talks directly to one person. Keep messages short and concise, because social media buries anyone who is not direct.

The fourth tip is scarcity. Create a feeling that the offer will run out. Jonathan points to an ad using two devices: the words "super offer" and a countdown clock. That clock speaks straight to the reptilian brain and pushes you to act before you miss out.

Is scarcity the same as exclusivity? No. Scarcity creates urgency, the fear of missing a benefit. Exclusivity creates belonging, selling the idea that buying puts you in a select group with special perks.

Why do realism, simplicity, and anchoring drive conversions?

The third tip is to bring the product closer to reality. People buy when they can picture the product in their real life. IKEA uses augmented reality so you can see if furniture fits your apartment, and clothing ads show the garment on a real person in motion.

The fifth tip is simplicity, where "less is more" applies literally [42:00]. Fewer elements mean the brain does not tire, which keeps it active and ready to decide. A clean Sony ad with the logo, a short line of text, and a call to action beats a page crammed with graphics.

The sixth tip is perceptual anchoring. When you place a product next to more expensive options, the consumer unconsciously perceives it as the cheapest and grabs it. Retailers use this constantly, and it is not a trick, just an understanding of how the mind compares prices.

The seventh tip is commitment. Your brand must show consistency between what it posts, advertises, and does. Aligning with a cause, like inclusion for people with disabilities, hooks consumers who feel a sense of belonging to that community.

How do you write a call to action that converts?

The bonus tip focuses on the call to action, the specific thing you want the user to do: buy, visit, follow, sign up, or download [51:00].

Keep it to two or three words. Jonathan recommends using hashtags to make your brand recognizable and emojis to boost engagement.

• Emojis increase the likelihood of interaction by more than 40% when they accompany your digital efforts.
• Power words like "free" and "urgent" push the brain toward action by triggering attention and urgency.
• Using the customer's name automatically captures attention and raises your chances of conversion.

When you address someone by name, whether Juan, Sandra, or Eduardo, you connect directly with the reptilian brain's need to feel personally seen.

How do you apply this to apps, B2B, and content strategy?

During the Q&A, Jonathan tailored the theory to real projects. For promoting an app, list the concrete benefits the user gains and lean on small-scale influencers so potential users can identify with them.

For B2B selling, business to business, decisions take longer, so emphasize benefits and shared brand commitments to speed up the decision.

For a new brand, he gave one honest reminder: content strategy takes time, sometimes six months to a year. Define your audience with a real face, study your competition, measure small wins, and do not get discouraged when early results feel tiny.

He also recommended three books worth reading: Buyology, Emotional Intelligence by Daniel Goleman, and La Neuropirámide Romano by Mexican neuroscientist Jaime Romano.
