The success of street marketing: FOMO or strategy?

The origins of guerrilla marketing and why it still works

Guerrilla marketing isn’t new. Jay Conrad Levinson challenged conventional advertising rules in the 1980s with his 1984 book Guerrilla Marketing, introducing an audacious concept: brands don’t need enormous budgets to create powerful impact; they need to be unforgettable. The term derives from guerrilla warfare, where unconventional tactics rely on surprise, strategy, and agility rather than size or resources.

Guerrilla marketing thrives on pushing creative boundaries to break through the clutter of traditional advertising, whether through striking street art, interactive installations, or unconventional events that spark curiosity and engage people on a deeper level. A clever idea on a pavement can generate global conversation overnight. Campaigns now integrate seamlessly with digital branding, social media amplification, and content marketing.

FOMO marketing tactics that actually drive behaviour

FOMO marketing uses humans’ reactive nature to create urgency and fear of missing out, encouraging users to take action, with research showing that adding countdown timers to limited-time offers boosted conversions by 147%.

More than half of people using social platforms experience FOMO. Research indicates that 60% of millennials make reactive purchases within 24 hours because of FOMO, especially when exposed to limited-time offers or product scarcity.

Flash sales on social media with captions stating how long the sale will last encourage immediate action whilst incentivising followers to regularly check their social pages. Creating members-only clubs where subscribers receive special discounts, deals, and early access to products encourages more individuals to sign up.

Where strategy ends

Guerrilla marketing is particularly effective for startups working with limited budgets, allowing them to create real-life experiences that resonate deeply with target audiences rather than pouring money into digital ads. Yet effectiveness and ethics aren’t always aligned.

FOMO-based CTAs increase landing page conversions by 202% compared to neutral phrasing, but overusing FOMO tactics can lead to audience fatigue, increased unsubscribes, or negative brand sentiment.

When creating real-time alerts, brands should focus on showing genuine activity rather than fabricating urgency; customers quickly spot and reject fake scarcity that doesn’t reflect actual limitations. Ethical FOMO marketing is about creating urgency without misleading customers, using clear messaging, setting realistic expectations, and delivering on promises to build trust and ensure long-term success.

Milan Design Week as case study

During Fuorisalone, some brands staged installations that perfectly combined these aspects of contemporary marketing, featuring limited access, temporary experiences, and spaces designed to be photographed and shared by those lucky enough to visit them.

Brands like Škoda, winner of the 2026 Fuorisalone Award, no longer simply display their products; instead, they create spaces where the public can enter, document their experience, post images, and discuss them online. Similarly, contemporary street marketing no longer merely speaks to the public but invites them to participate. It is precisely through a combination of guerrilla marketing tactics and the strategic use of FOMO that promotion becomes faster and more effective, increasing conversions alongside brand visibility.
