Mary Kate, our roundtable host and Head of Growth Marketing for North America at AB Tasty, leads efforts to help companies create impactful digital experiences through AB Tasty’s suite of experimentation, personalization, product recommendations, and site search tools.

AB Tasty’s integration with GA4 & BigQuery

Connecting AB Tasty with GA4 gives marketing teams insights into visitor behavior through advanced analytics on CPA, conversion rate, bounce rate, SEO, and traffic. This integration allows teams to use data from either tool to measure the impact of experiments pre- and post-rollout, generating data-backed hypotheses and fostering innovation.

Google BigQuery, a fully managed cloud data warehouse solution, offers rapid data storage and analysis at scale. With its serverless, cost-effective structure, BigQuery allows businesses to analyze large datasets efficiently, making it easier to make well-informed decisions.

With Google BigQuery, users can effortlessly execute complex analytical SQL queries and leverage built-in machine-learning capabilities.

Why is data from GA4 foundational to any CRO program?

In experimentation, data is the catalyst that drives actionable insights. Data flows in from multiple sources, and businesses generate detailed reports by working with partners to integrate tracking and tagging. But the question then becomes: what comes next? That’s where experimentation enters. Using data from tools like GA4, teams can transform hypotheses into tests, uncovering which changes impact user engagement or conversions most effectively.

GA4’s role extends further by providing a consistent framework for testing across platforms. When integrated with BigQuery, GA4 allows teams to cross-reference test outcomes with other data points, revealing not just what worked but why it worked. As Alex noted, “We gather good data, run good tests, and then verify results across disparate sources like BigQuery to see if what we tested had the expected downstream impact.”

Data accessibility and agility are also important. Trends evolve quickly, with viral content or market shifts requiring rapid adaptability. “Having partners like Google, with all data in one place, and a platform like AB Tasty, where experiments can be quickly set up, is essential for staying competitive” Alex emphasized.

How BigQuery powers scalable experimentation

With the growing volume of data, businesses need a way to consolidate and interpret it to drive impactful decisions. BigQuery, as Taige explained, is a robust cloud warehouse that streamlines data for meaningful insights, making it a key player in the experimentation ecosystem.

“Think of BigQuery as a filing cabinet for your organized data,” Taige noted. By consolidating disparate data sources, teams can create a unified view that informs testing and optimization efforts. Through this approach, tools like GA4 and BigQuery enable accurate decision-making that scales with the business. With BigQuery as the backbone, AB Tasty and AdSwerve can build on this structure to optimize user experiences through precise experimentation.

Beyond just data storage, BigQuery integrates with various Google Cloud tools and supports a wide range of use cases—from standard reporting to advanced machine learning. For marketers, this means fewer technical bottlenecks and quicker access to the data needed to stay agile. As Taige explained, “You may not need deep technical skills to access BigQuery’s benefits; the right partnerships and data structure can give you a powerful, accessible foundation.”

Leveraging BigQuery’s built-in AI and machine learning models

BigQuery offers an array of AI models for specific use cases—from translation and personalization to customer segmentation. These models add value by automating processes, such as localization or customer behavior prediction, allowing for smoother, more targeted marketing.

BigQuery’s flexibility means that companies can incorporate custom or third-party models, ensuring compatibility with a variety of AI solutions. This adaptability helps organizations innovate and iterate on experimentation programs, expanding what they can achieve with data.

Simplifying data access for marketing efficiency

For marketing teams, BigQuery’s role as a centralized data hub allows seamless data consolidation from platforms like Google Ads, Salesforce, and GA4. This integration ensures that marketers aren’t slowed down by fragmented data sources, freeing them to focus on insights and execution. As Taige highlighted, “The peace of mind that BigQuery provides comes from knowing that all data is consolidated and accessible, allowing teams to be nimble and creative.”

With BigQuery, marketers can view performance metrics, analyze customer journeys, and refine strategies—all within a unified environment. This lets teams optimize campaigns in real time as new data insights emerge.

Next-Generation capabilities enabled by Google Cloud

Looking ahead, digital  is paving the way for more advanced experimentation capabilities.  The conversation shifts to AI and machine learning, bringing new opportunities for personalization and optimization. As Mary Kate pointed out, while AI-driven insights can revolutionize customer experiences, many brands are still years away from realizing the full potential of these tools.

True value will come not from adopting every new tool but from understanding the foundational data supporting AI and asking the right questions about how these technologies can serve customer needs. Taige added, “If you don’t have a data strategy, you won’t have an AI strategy.” While AI amplifies data power, it requires organized, high-quality data to work effectively.

By consolidating and centralizing data through BigQuery, teams gain real-time insights and can make informed decisions. This data foundation enables the current wave of omnichannel strategies and sets the stage for future AI applications. Businesses that adopt this holistic approach—consolidating data, optimizing channels, and preparing teams for AI—will unlock new experimentation opportunities and drive impactful customer experiences.

With GA4 and BigQuery, businesses have the tools to streamline data consolidation and power next-generation experimentation. Ready to join your data and experimentation? Discover how AB Tasty can help bring data-driven optimization to life.

Experimentation Hotspots: Proven Strategies to Optimize Key Pages

When it comes to optimizing your website for better performance, experimentation is key to uncovering the areas that will make the biggest impact. Every page and interaction is an opportunity to boost conversions, streamline the user experience, and reduce friction. But with so many possibilities, where do you start testing? What are the key hotspots on your website that can deliver quick wins and meaningful improvements?

Finding the right areas to test can be tricky, but knowing where to focus is important for getting results quickly. That’s why we’ve identified five key questions to help guide your experimentation efforts:

  • Is the content relevant to “me” (the visitor)?
  • Is the next action clear?
  • What may be distracting?
  • What could cause anxiety?
  • What is creating urgency?

By addressing these questions, you can start identifying the areas on your website—what we call Experimentation Hotspots—that offer the most potential for improvement. In this guide, we’ll explore these important areas, from the homepage to the checkout funnel, that are ideal for testing. Whether you’re optimizing for mobile, app, or desktop, these tips will help you kickstart your experimentation journey and start making impactful changes. 

1. Homepage

The homepage is where you show people who you are and what your brand means. It serves as the gateway to various sections, from product categories to special offers, and is where users often return mid-session. Your homepage often sets the tone for the rest of the user’s journey, making optimization crucial.

One effective strategy is to experiment with the placement and labels of your call-to-action (CTA) buttons. Ensuring that users can quickly locate key actions, such as signing up or starting their shopping journey, can make a significant difference in engagement. Testing different CTA labels, such as “Explore Now” versus “Shop Now,” helps determine which drives the most conversions.

Additionally, it’s essential to test the layout and how content is presented. Category links, sales promotions, and other critical pieces of content should be placed in a way that draws attention without overwhelming users. Small adjustments—like changing the placement of sales banners or highlighting popular categories—can enhance the overall user experience and increase interaction with your content.

Areas to optimize

  • Header
  • Main Navigation
  • Categories
  • Content Pushes
  • Layout

The beauty brand, Lush, shifted its homepage messaging by testing two variations—one focused on self-care and another on gifting care packages. The version centered on gifting led to a 250% increase in engagement, showing how even minor tweaks in messaging can significantly improve user interactions.

2. Product listing page (PLP)

The product listing page (PLP) is where users begin narrowing down their choices. This page is most effective when visitors can scan and compare products easily, helping them make decisions more efficiently. While it might seem like there’s limited space to display information, there’s a lot of room for optimization that can smooth the path to purchase.

Testing how high-quality images, clear pricing, and CTAs like “Add to Cart” are displayed can improve product visibility. Adding reviews or badges like “Best Seller” can boost credibility and urgency. Experiment with hover effects to show additional details when users hover over a product.

Experiment with the placement and functionality of filters to make product discovery easier. Test whether a sidebar, dropdown, or dynamic filtering works best for your users. Simple adjustments to category labels or sorting options, like by price or ratings, can enhance the shopping experience.

Areas to optimize

  • Product Card Information (e.g., imagery, price, CTA)
  • Reviews and Badges
  • Hover States
  • Filters and Sorting Options
  • Headers/Banners

Clarins UK reintroduced the wishlist functionality to their PLP and PDP. This allowed users to save their favorite products for later, which led to a 1.54% increase in basket page views. It also increased the number of transactions by 1.83%, showing the value of small user experience enhancements. 

It’s also important to consider the differences between mobile and desktop experiences when testing. A solution that works well on desktop might not perform the same on mobile due to varying user behaviors. Despite a long-standing focus on mobile optimization, it’s still common to overlook these differences. 

3. Product display page (PDP) 

The product description page (PDP) is the centerpiece of any e-commerce experience and at the center of a customer journey. Many retailers are now asking, “How can we make the PDP feel more like a landing page?” With more customers arriving directly on PDPs from social media, rather than the homepage, the PDP often serves as the first touchpoint. This makes it even more crucial, as it’s where customers ultimately decide whether or not to make a purchase. Reducing friction and providing clear, relevant information are essential to driving conversions at this stage.

Testing how high-quality images, clear pricing, and CTAs like “Add to Cart” are displayed can improve product visibility. Adding reviews or badges like “Best Seller” can boost credibility and urgency. Experiment with hover effects to show additional details when users hover over a product.

Experiment with the placement and functionality of filters to make product discovery easier. Test whether a sidebar, dropdown, or dynamic filtering works best for your users. Simple adjustments to category labels or sorting options, like by price or ratings, can enhance the shopping experience.

Key areas to experiment with

  • Product Imagery and Descriptions: Ensure your images and descriptions are high-quality, answering common questions about the product (e.g., size, fit, material).
  • Call-to-Action Buttons: Test the wording, design, and placement of your CTAs to find what drives the most conversions.

Additional areas to optimize

  • Page Layout (order of information)
  • Product Images and Videos
  • Shipping & Return Messaging
  • Cross-Sell Items
  • Call to Actions
  • Reviews and User-Generated Content
  • Experience for New Visitors
  • Mobile vs Desktop Experience
  • Add-to-Cart Behavior & Mini Cart

French beauty product L’Occitane implemented a social proof widget on its PDP, showing how many people had recently viewed a product. The first variation displayed “X people are viewing this product,” while the second version said “Selling Fast.” This simple tweak created urgency and reassurance, leading to a 5.76% increase in transaction rate and a 3.36% increase in revenue per visitor. 

Social proof taps into user psychology—when customers see that many others are viewing or purchasing a product, it creates a sense of urgency and reduces anxiety, helping to drive sales.

4. Checkout funnel

The checkout process is where the real magic (or frustration) happens. It’s the final step in the customer journey, and even small obstacles here can lead to abandoned carts. Simplifying the checkout funnel can make the difference between completing a sale and losing a customer at the last moment. This stage is not just about speeding up the process—it’s also about building trust and ensuring customers feel confident in their purchase.

Optimizing your checkout involves refining everything from the mini basket to the confirmation page, making the experience as seamless as possible. 

Testing opportunities

  • Product Imagery and Descriptions: Ensure your images and descriptions are high-quality, answering common questions about the product (e.g., size, fit, material).
  • Call-to-Action Buttons: Test the wording, design, and placement of your CTAs to find what drives the most conversions.

Additional areas to optimize

  • Basket Summary
  • Step Progression
  • Login and Guest Checkout Options
  • Account Creation
  • Form Field Labels & Microcopy
  • Payment Methods
  • Coupon Field Visibility & Design
  • Cross-Sells & Product Recommendations
  • Confirmation Page

Calvin Klein ran a test where they displayed a “last viewed” carousel on the empty cart page after a user removed all items from their cart. This reminded users of previously viewed products, reducing the bounce rate by 4.19% and increasing orders by 7.5%. By preventing the cart from feeling empty and offering product recommendations, the brand successfully retained potential customers and increased conversions.

5. Personalization

Personalization is key to creating a unique and engaging experience for each visitor. In an online shopping survey, 88% of respondents rated personalized product recommendations as helpful when asked to score them on a scale of 1-5 (with 5 being very helpful and 1 not helpful). By understanding user behavior and segmenting audiences, you can deliver tailored content that enhances user satisfaction and drives higher conversions. Personalization not only improves the shopping experience, but also fosters customer loyalty, encouraging repeat purchases over time. 

Start with

  • Behavioral Targeting: Personalize content based on how users interact with your site. For example, use data on past clicks or scrolling behavior to serve more relevant offers.
  • Abandoned Cart Reminders: Encourage users to complete their purchase by reminding them of items left behind.

French fashion retailer, Maje created a personalized campaign for users who abandoned their carts. When those users returned to the site, they were shown the products they had previously left behind, making it easy for them to continue shopping. This strategy resulted in an 11% increase on click rate on the pop up, with a significant portion of those users completing their purchases.

In addition, AB Tasty tools like Emotions AI can help recognize emotional triggers or online body language (e.g., scroll behavior or clicks) to tailor content even further, providing users with the most relevant experiences.

Wrapping up

From optimizing your homepage to personalizing the user experience, every aspect of your website offers an opportunity for growth. Even small tests—like changing the placement of a carousel or adjusting CTA wording—can lead to significant results.

By regularly experimenting and optimizing key hotspots on your site, you can improve user engagement, reduce friction, and ultimately increase conversions. Remember, every site is different, so test frequently and use data to inform decisions. This approach helps ensure that you’re continually refining your site for optimal success.
