How Performance Max and AI-Driven Ads Made My Brand a Market Leader
The global e-commerce market is projected to grow by 10.4% in 2023, signaling a continued shift toward digital shopping. However, with increasing competition, brands must leverage AI-powered advertising to stand out. Google Ads, enhanced by artificial intelligence, offers sophisticated tools like Performance Max campaigns, Web-to-App Connect, and AI-driven audience segmentation—all proven to boost conversions and return on ad spend (ROAS).
Leading brands like L’Oréal Vietnam, Samsung, and Yuu have already harnessed these strategies to achieve remarkable results. For instance, L’Oréal Vietnam saw a 4.1X higher ROAS using Performance Max, while Samsung increased conversions by 70% through AI-driven first-party data strategies. As we explore these success stories, we’ll uncover how AI is reshaping digital advertising and how your brand can replicate these results.
I. Leveraging Performance Max Campaigns for ROAS
Performance Max campaigns represent a transformative advancement in Google Ads, enabling advertisers to maximize reach across Google’s full advertising inventory—including Search, Display, Discover, Gmail, and Maps—through a single, AI-driven campaign. Unlike traditional manual bidding strategies, Performance Max leverages Google’s AI to dynamically optimize bids, placements, and creatives based on real-time performance signals. For e-commerce businesses, integrating Performance Max with platforms like Shopify or WooCommerce simplifies product feed synchronization, ensuring seamless campaign execution.
The effectiveness of Performance Max is underscored by L’Oréal Vietnam’s results, where the campaign achieved a 4.1X higher return on ad spend (ROAS) and a 13X higher conversion rate compared to previous Smart Shopping efforts. During its December campaign, Performance Max contributed 40% of ad traffic to L’Oréal’s online store, culminating in a 338% ROAS. This success highlights the AI’s ability to target high-intent shoppers and adjust bids autonomously for optimal performance.
To harness Performance Max, advertisers must provide high-quality creative assets for AI optimization and define clear conversion goals to guide the system’s learning. By consolidating cross-channel reach and automating optimization, Performance Max empowers brands to drive scalable results while reducing manual intervention.
II. Integrating Web-to-App Strategies for Higher Conversions
Mobile apps are a critical driver of customer loyalty, with 87% of retailers agreeing that app users have a higher lifetime value than non-users. However, many shoppers still discover brands via mobile web, creating a disconnect. Web-to-App Connect bridges this gap by deep-linking users directly to in-app content, improving conversion rates by 2X compared to mobile web. This seamless transition eliminates friction, enhancing user experience and retention.
Fashion retailer Boohoo exemplifies this strategy’s potential. By implementing Web-to-App Connect, Boohoo achieved a 25% revenue increase, a 5.5X higher conversion rate, and an 83% lower cost per conversion when driving traffic to its app instead of its mobile site. These results highlight the power of unifying web and app experiences to maximize ROI.
To optimize Web-to-App Connect, retailers should leverage Google Ads capabilities such as AI-powered bidding to prioritize high-value app users. Tracking in-app conversions is essential for refining targeting and bidding strategies, ensuring campaigns align with user behavior. Additionally, enabling deep linking directs users to relevant in-app pages, streamlining the path to purchase.
For retailers aiming to scale performance, integrating Performance Max campaigns can further amplify results. Performance Max leverages Google’s AI to optimize ad delivery across Search, Display, Discover, Gmail, and Maps, ensuring maximum reach and efficiency. By combining Web-to-App Connect with Performance Max, brands can create a cohesive omnichannel strategy that drives higher conversions and customer lifetime value.
III. Harnessing First-Party Data with AI-Driven Ads
The deprecation of third-party cookies has elevated first-party data as the cornerstone of modern digital marketing, with brands leveraging these insights achieving up to 2.9X higher revenue compared to those relying solely on third-party sources. This shift underscores the critical role of AI-driven advertising solutions, such as those offered by Topkee through Google Ads, which enable businesses to transform raw data into actionable strategies. Topkee’s comprehensive approach begins with a thorough website assessment and analysis, utilizing advanced scoring tools to identify SEO gaps and optimize content structure—ensuring alignment with search intent and maximizing visibility for high-intent audiences.
To operationalize first-party data, Topkee developed TTO CDP, a centralized platform for managing multiple ad accounts, budget allocation, and conversion tracking. This system automates event-based data synchronization with Google Ads, enabling precise audience segmentation and dynamic bidding strategies.
AI-driven personalization is amplified through keyword research and creative production, where Topkee combines competitor analysis and AI-generated ad copy to align messaging with user intent. Our remarketing strategies, powered by TTO attribution tools, analyze behavioral triggers to deliver contextually relevant ads—proven to increase purchase likelihood by over 70% compared to generic placements. Performance Max campaigns further automate multi-channel targeting, leveraging Smart Bidding to maximize conversions while maintaining ROI transparency through detailed advertising reports.
IV. Campaigns for Retention and Engagement
For brands with mobile apps, App Campaigns for Engagement (ACe) are a powerful retention tool within Google Ads. These AI-driven campaigns leverage machine learning to re-engage users by promoting personalized in-app actions, such as completing purchases or redeeming rewards. Topkee's Google Ads services emphasize maximizing ROI through intelligent campaign setups, by combining dynamic creatives, smart bidding, and data-driven audience segmentation.
A key advantage of ACe is its integration with Performance Max (Pmax), another AI-powered campaign type offered by Google Ads. Pmax complements ACe by optimizing bids across multiple channels to target high-value users. Topkee's approach includes initializing TTO to set conversion events and automate data synchronization with Google Ads. This ensures accurate attribution of in-app actions, enabling brands to measure engagement metrics like purchase frequency or reward redemptions.
To maximize Ads performance, Topkee implements several best practices derived from its Google Ads expertise: First, setting clear engagement KPIs aligned with business goals. Second, deploying dynamic creatives tailored to user behavior patterns identified through TTO’s attribution reports. Third, leveraging AI bidding strategies like Target ROAS to prioritize high-value segments.
V. Merchant Differentiation and Competitive Insights
In a crowded e-commerce market projected to grow 10.4% globally in 2023, effectively communicating unique value propositions—such as fast shipping, regional pricing, and promotions—is critical for conversion optimization. Google Merchant Center's competitive visibility reports and best-seller data enable brands to benchmark performance, refine inventory strategies, and identify market gaps. For instance, highlighting promotions in Shopping ads can attract deal-sensitive shoppers searching for keywords like "discount [product category]" or "best price [product]." Additionally, leveraging Performance Max campaigns—which consolidate Google Ads inventory across Search, Display, and Maps—helps brands dynamically showcase differentiated offers while optimizing bids through AI. According to internal data, L'Oréal Vietnam achieved a 4.1X higher ROAS using Performance Max by aligning ad creatives with localized promotions and shipping benefits. To sustain competitiveness, retailers should prioritize real-time insights from Merchant Center's Reporting API to adapt pricing, shipping options, and promotional messaging based on regional demand fluctuations and competitor benchmarks.
VI. Building Shopper Confidence with AI-Powered Solutions
Hong Kong shoppers face a “confidence gap”, spending 7+ hours researching purchases due to information overload and disinformation. AI-powered solutions like Performance Max and App Campaigns for Engagement (ACe) address this challenge by leveraging first-party data and Google's AI to deliver hyper-relevant messages across Search, YouTube, Display, and Maps. For instance, Samsung Hong Kong utilized Customer Match and AI-generated Google Ads keywords to target males aged 35-44 interested in outdoor photography, driving a 70% conversion lift and 2X sales for Galaxy S23. Similarly, Yuu's Performance Max campaign achieved a 23% cost efficiency improvement while doubling conversions by serving optimized creatives across channels. These AI-driven strategies demonstrate how precise audience targeting and cross-channel automation can shorten purchase journeys while building trust.

Additionally, Web to App Connect enhances mobile conversions, delivering 2X higher rates by directing users to in-app content. These innovations align with the growing emphasis on first-party data and omnichannel strategies, as demonstrated by Samsung's 70% conversion lift using Customer Match and AI-driven keyword optimization. The shift toward AI-driven, data-centric advertising will continue to redefine retail marketing efficiency.
