Millennials and Gen Z might seem similar at first glance: both are digitally fluent, socially aware, and constantly online. But beneath the surface, they’re shaped by very different experiences, values, and expectations.
One group remembers the sound of dial-up internet; the other grew up with Wi-Fi as a given. One came of age during the rise of social media, the other during a time when content moves at the speed of a scroll.
For marketers, these differences aren’t just interesting; they’re critical. Creating AI programmatic advertising campaigns that resonate with both groups means understanding not just where they spend their time, but how they think, what they care about, and why they connect with certain messages over others.
Explore what sets them apart, where they overlap, and how brands can meet each generation where they are, without losing the other in the process.
Who Are Millennials?
Born between 1981 and 1996, Millennials now make up 74.2 million people, or 21.8% of the U.S. population, according to Pew Research Center.
Today, many are juggling careers, families, mortgages—or at least thinking about them. They’ve moved well beyond avocado toast stereotypes and are making major life decisions that influence how they engage with brands.
Also known as Gen Y, Millennials are considered digital natives, but their relationship with technology is unique. They witnessed its evolution firsthand, from flip phones to smartphones, dial-up to fiber. The combination of exposure and adaptability has made them both tech-savvy and pragmatic about how they use it.
Education plays a key role, too. Around 39% of Millennials ages 25 to 37 have a bachelor’s degree or higher, outpacing previous generations at the same age. Their educational background helps shape their preferences: they’re curious, information-driven, and tend to look for substance behind the marketing.
Motivated by Meaning
Millennials value purpose. While compensation and convenience still matter, they’re far more likely to engage with brands that stand for something, whether it’s sustainability, education, or equity.
Marketing that taps into a cause—or clearly explains the why—tends to resonate more than a basic product pitch.
Relationships Matter (Even with Brands)
Millennials value trust and transparency in relationships, and that includes the brands they buy from. They prefer companies that communicate like humans and foster a sense of connection.
Messaging that feels friendly, honest, and conversational tends to work better than overly formal or corporate tone.
Fluent in Tech, Comfortable with Change
They didn’t grow up with smartphones, but they learned fast. Millennials are comfortable with digital tools, social media, and online shopping. What sets them apart is their adaptability: they’ve navigated a constantly changing tech landscape and learned to evolve with it.
Always Learning
Millennials are curious. Many see education as a lifelong journey and actively seek out new information. Marketing that explains, teaches, or offers useful insights tends to capture their attention.
Understanding Gen Z
Born between 1997 and 2012, Gen Z is the newest major generation shaping the cultural and consumer landscape. With 70.8 million people making up about 20.8% of the U.S. population, they’re quickly becoming a dominant force in markets everywhere.
What sets Gen Z apart is their complete immersion in digital life. Not only do they use technology—they live it. Unlike Millennials, who adapted to the rise of the internet and smartphones, Gen Z has never known a world without them. Scrolling, streaming, shopping, and socializing happen seamlessly, often all on the same screen.
But beyond the screen time statistics (which clock in at over 6 hours a day on their phones), there’s a deeper set of values and behaviors that marketers need to understand.
Digital Is Simply the Default
Gen Z expects technology to work: no glitches, no lag, no complicated interfaces. They’re experts at navigating apps, multitasking across platforms, and discovering new trends at lightning speed.
If your digital presence isn’t polished and mobile-optimized, you risk losing their attention before you even start.
Mental Health Awareness Is Front and Center
Gen Z has helped break down long-standing stigmas around mental health. They’re more open than previous generations to talking about anxiety, depression, and self-care, and they look for brands that acknowledge these realities in a genuine, respectful way.
Social and Environmental Responsibility Matter
Gen Z cares deeply about social justice, equity, and sustainability. They expect companies to not just say the right things but to actively demonstrate their commitment through transparent actions.
If they sense performative activism—marketing that’s all talk and no action—they’ll call it out.
Impacted by Pandemic and Economic Shifts
Growing up during economic uncertainty and a global pandemic has made Gen Z more cautious and thoughtful about spending. They’re savvy researchers and budget-conscious shoppers, often exploring secondhand or sustainable options before making purchases.
How to Win Over Millennials with Programmatic Advertising
Millennials are now well-established in their careers and personal lives, which influences how they engage with brands. To connect effectively, marketers need to focus on authenticity, meaningful engagement, and relevant content.
Tell Authentic Stories
Millennials respond strongly to storytelling that reflects their values and experiences. Campaigns incorporating real-life challenges, nostalgia, or social purpose tend to resonate more deeply.
Collaborate with Relatable Influencers
Partner with digital creators who share genuine experiences and interests with this demographic. Millennials often prefer influencers who feel like trusted friends rather than distant celebrities.
Create Community-Driven Content
Social media efforts should foster genuine interaction and connection, whether through Facebook groups, Instagram conversations, or interactive events. Millennials value feeling part of a community.
Leverage User-Generated Content
Encouraging customers to share reviews, photos, and stories builds trust and strengthens brand credibility.
Invest in Video That Educates or Entertains
Short, informative videos that provide value, such as how-tos, behind-the-scenes looks, or compelling brand stories, are particularly effective.
Maintain an Effective Email Strategy
Unlike younger generations, Millennials still engage with well-crafted emails that deliver relevant offers, insights, or updates.
Reaching Gen Z Without Getting Ghosted
As discussed before, Gen Z has very high expectations for brands: they want transparency, value, and seamless digital experiences.
Prioritize Authenticity
Gen Z quickly detects the lack of sincerity. Brands that communicate honestly and showcase real people and stories build stronger relationships.
Deliver Concise, Engaging Content
With short attention spans, Gen Z favors content that hooks immediately and delivers value quickly, be it through entertainment, information, or both.
Demonstrate Genuine Commitment to Social Causes
Mental health awareness, environmental responsibility, and social equity are important to this generation. Brands should authentically support these causes rather than treating them as trends.
Integrate Social Commerce Smoothly
Gen Z prefers to discover and purchase products directly through social media, so integrating shopping features into social platforms is essential.
Encourage Active Participation
Interactive content like challenges, polls, and co-creation opportunities engage Gen Z effectively, fostering a sense of ownership and community.
Where Gen Z and Millennials Overlap
While Millennials and Gen Z have distinct preferences, there are important areas where their behaviors and expectations align.
1. Authenticity Is Non-Negotiable
Both generations expect brands to be honest and transparent. They respond negatively to over-polished or insincere messaging. Be it a social post or a paid ad, authenticity builds trust and loyalty.
2. Storytelling Matters
Narrative-driven content that connects emotionally performs well across the board. Whether it’s a brand’s origin story, a customer testimonial, or a purpose-driven campaign, both Millennials and Gen Z appreciate stories that feel genuine and relatable.
3. Mobile-First Experiences Are Essential
Mobile phones are the primary devices for both groups. From browsing and shopping to watching videos and engaging on social media, every touchpoint should be optimized for fast, seamless mobile use.
4. Personalization Should Feel Natural
Relevant, data-driven content is appreciated when done thoughtfully. Both generations value personalized experiences but are wary of overly intrusive tactics. Smart segmentation and respectful targeting go a long way.
5. Omnichannel Consistency Builds Confidence
Millennials and Gen Z expect a unified brand experience both online and offline. Consistent messaging and visuals across social media, websites, emails, and physical locations create stronger brand recognition and trust.
6. Purpose-Driven Marketing Resonates
Brands that demonstrate a real commitment to causes usually earn respect and engagement from both generations. However, it must be authentic and visible in actions, not just words.
7. Influencers Still Influence
Both generations trust influencers, especially those who come across as authentic and relatable. Micro-influencers with niche followings often outperform celebrities in building genuine connections.
8. Interactive and Engaging Formats Work
Polls, quizzes, challenges, and other interactive content boost engagement with both Millennials and Gen Z. These formats invite participation, making consumers feel part of the brand story.
9. Don’t Sleep on Connected TV (CTV) Advertising
CTV is an increasingly effective channel to reach both Millennials and Gen Z. Currently, Millennials lead with about 59 million viewers, but Gen Z is rapidly closing the gap—expected to grow from roughly 47 million viewers in 2021 to over 56 million by 2025.
Leveraging CTV allows brands to deliver high-quality, targeted video content where these audiences are already engaged.
