In a market flooded with data, features, and rational appeals, the most successful brands connect on a deeper, emotional level. To get there, marketers need tools that go beyond surveys and focus groups. One of the most powerful methods is the Zaltman Metaphor Elicitation Technique (ZMET) that is a research-based approach that uncovers the deep metaphors driving customer perception and behavior.
This blog post explains what ZMET is, how it works, and how you can apply ZMET metaphors to transform product marketing from transactional to transformational.
What Is ZMET?
ZMET is a qualitative research methodology developed by Harvard Business School professor Gerald Zaltman. It’s designed to explore how consumers think and feel about a brand, product, or category by analyzing the metaphorsembedded in their mental models.
Core Idea:
Much of human thought is metaphorical and occurs at the unconscious level. ZMET reveals these hidden structures through images and storytelling—not just words.
Why It Works:
95% of thinking happens below conscious awareness.
Metaphors shape how people frame their experiences, even when they’re not aware of it.
Marketing that aligns with these metaphors feels intuitively right and drives deeper engagement.
How ZMET Works
Image Elicitation
Participants are asked to collect 8–12 images (from magazines, online, personal sources) that represent their thoughts and feelings about a product, brand, or topic.One-on-One Interviews
Using the images as prompts, interviewers explore the why behind each image:
"What does this image mean to you?"
"How does it relate to [product/brand]?"
"What story does this image tell?"
Laddering and Probing
The interviewer uses laddering techniques to unpack deeper meaning—moving from attributes → consequences → values → metaphors.Thematic Analysis
Researchers analyze the data to identify recurring metaphors and deep structures such as:
Journey
Container
Balance
Transformation
Connection
Control
Constructing the "Consensus Map"
This is a visual model that captures the dominant metaphors and mental models shared by the group.
Common Deep Metaphors (and Their Marketing Implications)
Metaphor | Description | Marketing Application Example |
---|---|---|
Journey | Life is a path; progress and movement matter | Fitness apps, career coaching, customer onboarding |
Container | In/out boundaries—safety, privacy, inclusion | Skincare (protective barrier), data security |
Transformation | Change and evolution are desirable | Beauty products, education, personal growth |
Balance | Harmony vs. chaos | Work-life solutions, dietary supplements |
Connection | Belonging and relationships | Social media, family-oriented brands |
Control | Autonomy, agency, mastery | Financial services, home automation |
Applying ZMET Metaphors in Product Marketing
1. Brand Positioning
Use the core metaphor to reframe your brand’s narrative.
Example: A fintech app might discover users view money as control. Marketing can then emphasize "take control of your future" or "empower your spending."
2. Product Design and Naming
Align product features or even names with the metaphorical structure.
Example: If customers see self-care as transformation, a beauty product might emphasize “metamorphosis,” “renewal,” or “rebirth” rather than just “hydration.”
3. Ad Creative and Storytelling
Craft visuals and stories that mirror users’ unconscious metaphors.
Example: For a wellness app aligned with the journey metaphor, ads could show a visual narrative of progress over time, using map imagery or before/after arcs.
4. Packaging and UI
Even tangible elements like packaging and interface design can embody metaphors.
Example: A container metaphor might lead to packaging that looks like a safe, vault, or sanctuary—creating a visceral sense of protection.
5. Customer Experience Design
Infuse metaphors into onboarding, loyalty programs, and touchpoints.
Example: A connection metaphor may inspire community-building features, referral programs, or personal greetings from staff.
Real-World Examples
Coca-Cola: Uses the connection and transformation metaphors—“Open Happiness” positions the drink as a portal to joy and shared moments.
Apple: Embeds the control and transformation metaphors—products give users power over their creative and digital lives.
Nike: Leverages the journey metaphor—"Just Do It" is not about winning but stepping into progress.
Benefits of Using ZMET in Marketing
Uncovers what customers can’t articulate in surveys.
Drives emotional resonance in branding and messaging.
Aligns product features with underlying desires.
Creates a differentiated narrative in competitive markets.
Informs long-term brand strategy, not just tactical campaigns.
When to Use ZMET
Launching a new product or brand in a saturated market.
Rebranding or repositioning an existing brand.
Exploring customer resistance or loyalty triggers.
Developing campaigns that require emotional depth.
In summary
ZMET is a strategic lens that reframes how you understand customers. By tapping into deep metaphors, you move beyond superficial messaging and create marketing that resonates at the level where real decisions are made: the unconscious. If you want your brand to be remembered, trusted, and chosen, don’t just speak to the mind. rather speak to the metaphors beneath it.
