Why TikTok Ads Perform Better Than Facebook & Instagram for Gen Z in the USA

There has been a seismic shift in online marketing over the past few years, and it's being led by one demographic: Gen Z. Born between the late 1990s and early 2010s, this generation has revolutionized the way brands need to approach content, connection, and commerce.
Developing at the forefront of this shift is TikTok digital advertising—a extremely impactful, short-form video strategy that outperforms more traditional websites like Facebook and Instagram in all major metrics. TikTok is also Gen Z's first choice as an entertainment platform as well as a platform for discovering products, culture, and brands.
Therefore, brands can no longer rely on static posts or stories alone to engage. They need to have bold, scroll-stopping, short-form content and a TikTok-first mentality to stay in the game in 2025 and beyond.

Why TikTok Digital Marketing Reigns Supreme Over Facebook & Instagram

Higher Levels of Engagement with Short-Videos

TikTok's full-screen, short-form aesthetic just demands more attention than a messy Facebook feed or an over-filtered Instagram post. Gen Z users are spending more time interacting with content, liking, commenting, and sharing videos at a much higher clip than they do on other platforms.
Unlike Facebook, where content tends to get lost in algorithmic noise, or Instagram, where aspirational aesthetics take center stage, TikTok thrives and survives on unapologetic creativity and authenticity—thus a paradise for brand storytelling.

Algorithm-Based Content Discovery for Greater Reach

TikTok's "For You" page is filled algorithmically based on the interest of every user. That is, small businesses with zero followers can become viral overnight if the content is of the right tone.
With TikTok online marketing, you're not only paying to reach your fans—you're paying to reach the audience that matters. This makes it more of a level playing field for new and emerging brands, providing a reach advantage Facebook and Instagram simply can't match.

AI-Driven Ad Personalization for Targeted Marketing

TikTok employs AI to show users extremely personalized content, based on their behavior, likes, and previous engagement. What this implies is that ads are not perceived as ads—they're perceived as the type of content the user already willingly consumes.
For advertisers, this personalization boosts CTR (click-through rate) and ROAS (return on ad spend). With the likes of Facebook subject to privacy-led targeting constraints, digital advertising TikTok is more effective and targeted.

How Brands' TikTok Ads Deliver Better ROI

Lower Cost-Per-Click than Instagram & Facebook

One of the most tangible benefits of advertising on TikTok is affordability. On average, TikTok has a much lower cost-per-click (CPC) and cost-per-thousand impressions (CPM) compared to its competitors.
This allows brands to run low-budget test campaigns and only scale up what works—great for performance and growth marketers.

TikTok Ad Virality Compared to Regular Social Ads

Traditional Facebook or Instagram advertising usually lives in silos—run, they expire, and that's it. TikTok, on the other hand, allows organic virality even for paid content.
With ad formats like Spark Ads, you can amplify creator-created content, fueling credibility and engagement. Organic and paid reach combined means your ROI isn't merely the paid spend—it can snowball.

Interactive Ad Units That Drive Engagement

TikTok ads aren't something that are scrolled past - they're something that are interacted with. With Branded Hashtag Challenges, Duets, and Poll Stickers, two-way engagement is the default.
This interaction not only makes TikTok a top-of-funnel discovery platform but also a mid- and bottom-funnel conversion driver—especially when paired with conversion-fueled marketing TikTok shop strategies that convert interest into action.

Case Studies: Business That Have Switched from Facebook/Instagram to TikTok

Case Study: ELF Cosmetics
ELF Cosmetics grabbed headlines when it shifted ad spend from Instagram and Facebook to TikTok and launched the now-iconic "Eyes, Lips, Face" campaign. It became one of the best branded hashtag campaigns in history with over 4 billion views.
Their shift to TikTok brand marketing was due to the fact that they realized Gen Z craved real content rather than overproduced perfection. The outcome? Increased website traffic, app downloads, and ultimately—sales.
Engagement & ROI Comparison
Facebook ROI (Q2 2023): 2.7x
Instagram ROI (Q2 2023): 3.1x
TikTok ROI (Q2 2023): 5.4x
When brands are optimizing for tiktok-native content, creator collaborations, and data-targeting, results are twice as likely to happen as on Meta platforms.

Best Marketing Strategies to Promote TikTok Shop among Gen Z

Influencer Usage for Real Engagement

Gen Z is more likely to believe influencers than they would in regular ads. Partnering with micro-influencers with niche expertise can make your TikTok Shop offerings appear like necessities and not forced sales pitches.
With cost-cutting, credibility-building shop marketing efforts such as influencer-driven campaigns and affiliate marketing, brands can maximize credibility at a reduced cost.

Running Interactive Campaigns (Challenges, Duets, Polls)

Involve your audience in the brand experience. Getting people to sing a duet or challenging them can make Gen Z users feel individually invested in your campaign.
Interactive formats don't just build brand equity—they also drive conversions. User-participation campaigns always register higher engagement and lower CPAs.

Optimizing TikTok Shop Ads for Seamless Shopping Experiences

Use TikTok Shopping Ads to facilitate easier purchasing. Improve your product detail pages with:

• High-quality photos
• Short demo clips
• User-generated content
• Open prices and reviews

By adding these to your TikTok digital marketing campaign, you offer a frictionless, fast, and native path to buy.

Conclusion

TikTok is not just Gen Z's favorite app—it's their mall, search engine, and content platform all in one. In the battle of platforms, digital marketing TikTok beats Facebook and Instagram on engagement, ad performance, and ROI every single time.
Brands marketing to Gen Z can no longer play it safe on mainstream channels. They need to meet their audience where they reside—at TikTok—and market in a language they use: authentic, quick, and entertaining.
