Google Search & Gen Z: Why AI-Powered SEM is the New Shopping Trend
In an era where 80% of Gen Z shoppers begin their product discovery on Google—outpacing even social media platforms—the search giant has solidified its position as the ultimate digital shopping companion for this demographic. Recent data reveals that signed-in users aged 18-24 conduct more daily searches than any other age group, with visual search tools like Google Lens experiencing 65% YoY growth. With advancements such as AI Overviews, visual search tools, and adaptable ad formats, Google is strengthening its leading position in the Google SEM realm. This shift in user behavior aligns with revolutionary AI innovations—ranging from AI Overviews processing 1.5 billion monthly queries to Circle to Search emerging as Gen Z’s gesture-based discovery tool—that are redefining the norms of search engine marketing (SEM). For brands, understanding this paradigm isn't just advantageous; it's critical for survival in an increasingly AI-driven commerce landscape.
I. Why Google Search Dominates Gen Z Shopping Journeys
Gen Z's reliance on Google Search stems from three fundamental advantages that align perfectly with their digital behaviors. First, the sheer volume of queries—over five trillion annually worldwide, with Gen Z leading per-capita usage—creates unparalleled touchpoint opportunities. Unlike millennials who split attention between platforms, 80% of Gen Z uses Google for end-to-end shopping activities, from discovery to purchase validation. Second, AI-powered features satisfy their preference for intuitive interactions: 10% of Gen Z searches now begin with Circle to Search's screen-circling gesture, while multimodal queries (combining text, images, and voice) account for 20% of Lens' 100 billion visual searches. Most critically, Google has earned Gen Z's trust as a decision-making ally—70% use it to verify social media discoveries, and 1 in 4 Lens searches reveal commercial intent. This trifecta of volume, UX alignment, and trust makes search indispensable for reaching this demographic.
II. Key Innovations Driving Gen Z Engagement
Google's recent AI advancements have transformed Search from an information retrieval tool into an intelligent shopping assistant. AI Overviews—already serving 1.5 billion users monthly—exemplify this shift by handling complex, long-tail queries like "how to keep suits wrinkle-free on long flights," which traditional keyword matching would struggle to address. For Gen Z, visual search tools are equally transformative: Lens not only identifies products from photos but now provides price comparisons and inventory checks across retailers, while Circle to Search lets users investigate Instagram posts or YouTube frames without app-switching. Maybe the most game-changing aspect is AI Mode’s reasoning capacity, which enables conversational follow-ups that triple the average length of queries. These innovations collectively address Gen Z's demand for contextual, frictionless discovery—whether they're researching "living room storage ideas" (like IKEA Greece's 7X revenue-driving campaign) or comparing flat whites to cappuccinos.
III. Business Opportunities for Forward-Thinking Marketers
Savvy brands are leveraging these innovations to create unprecedented SEM Google efficiencies. IKEA Greece's approach showcases the effectiveness of adapting to Gen Z's evolving search habits—through the use of broad match keywords for room-specific queries ("bathroom furniture") and Demand Gen campaigns featuring interactive video ads, they achieved 62% more site visitors and 20% higher ROAS. Similarly, AI-powered solutions like Search Campaigns with AI Max now deliver 27% more conversions at comparable CPA by dynamically adapting ads for AI Overview placements. The emergence of ads within AI Overviews (currently in US/English markets) and AI Mode responses presents untapped inventory, while visual search optimization unlocks Lens' 25% commercial intent rate. Critically, these tools don't require creative overhauls—repurposing existing assets for multi-format deployment (like displaying unused headlines as secondary links) has already boosted engagement by 15% in tests.
IV. Overcoming SEM Challenges in the AI Era
Despite these opportunities, brands encounter valid challenges in adjusting to AI-powered search. John Lewis' experience highlights the data infrastructure demands—their legacy systems' once-daily data syncs caused bidding inaccuracies until server-side Google Tag Manager (sGTM) enabled real-time profit tracking, boosting Search profits by 20%. Another challenge lies in balancing broad match's reach (crucial for capturing Gen Z's natural language queries) with precision—solved through layered audience signals and AI-powered Smart Bidding. Perhaps the most pervasive issue is organizational inertia; as Google's Brendon Kraham notes, 15% of daily searches are entirely new, requiring continuous testing frameworks rather than static keyword lists. Brands succeeding in this space treat SEM Google as an agile discovery engine—IKEA Greece's weekly creative optimizations and John Lewis' 18-month sGTM implementation both reflect this iterative mindset.
For brands lacking such infrastructure, solutions like Topkee’s SEM advertising report analysis service provide actionable insights through keyword and ROI reports, bridging gaps in real-time decision-making. Topkee’s keyword research tools leverage AI to dynamically expand keyword lists while maintaining relevance, ensuring ads align with evolving search intent without sacrificing efficiency.
V. The Future of SEM Google: Where Gen Z and AI Converge
Looking ahead, three trends will define next-generation SEM Google strategies. First, the rapid expansion of AI Overview ads—projected to cover all English markets by 2025—will make "position zero" placements essential for high-intent queries. Second, visual search monetization will mature, with Lens and Circle to Search developing dedicated ad formats (beta tests already show 40% higher CTR for visual-first product listings). Most transformative will be cross-channel measurement tools addressing Gen Z's zigzag path between social discovery ("backpack on TikTok") → Search validation → in-app purchase. Early adopters of unified attribution—like John Lewis' multi-touch profit tracking—are seeing 4% higher target ROAS by connecting these dots. As AI Overviews begin surfacing comparison tables and product specs directly in results, brands must optimize for "decision-ready" content that meets Gen Z's expectation for instant, trustworthy information.
For marketers looking to replicate such success, Topkee's SEM Google services offer a streamlined approach. Our AI-powered keyword research tools pinpoint high-intent search queries, and our creative optimization framework repurposes existing assets to enhance engagement levels. Topkee’s platform-agnostic solutions, like cross-channel performance tracking and automated bid adjustments, enable brands to adapt existing campaigns for multi-format deployment.

Conclusion: Meeting Gen Z Where They Search
The data is unequivocal—Google Search isn't just surviving the age of social and AI; it's thriving as Gen Z's preferred discovery engine by evolving faster than competitors. Brands that follow IKEA Greece’s broad match tactics, John Lewis’ real-time optimization methods, and Google’s own AI-focused ad solutions will gain outsized advantages in this new era. With 80% of non-branded searches now occurring on Google and Gen Z's commercial queries growing 10% faster than other demographics, the time for strategic investment is now. Whether it’s through optimizing for visual search, securing placements in AI Overviews, or upgrading cross-channel measurement, proactive marketers need to align with the actual search behaviors of digital natives. For brands ready to transform search curiosity into commercial impact, the tools and blueprints exist; the imperative is decisive action.
