How Supersports Vietnam Achieved a 16.6% AOV Lift With Zotasell AI Upsell

Supersports Vietnam didn’t have a traffic problem. Shoppers were happily browsing their massive catalog of fitness gear, checking out exactly what they came for, and that’s all.

For a major Shopify retailer, this flat Average Order Value (AOV) was quietly eating into their margins. With thousands of SKUs, the site simply couldn’t guide customers toward complementary items at the right time fast and smartly.

That’s where Zotasell changed the equation.

In this post, we’ll break down how Supersports Vietnam combined Zotasell’s AI recommendations with Lazy Load Infinite Scroll to turn passive browsers into high-value buyers.

About Supersports Vietnam

Supersports is one of Southeast Asia’s most established sports and fitness retailers, with active stores in both Vietnam and Thailand. Their catalog spans athletic footwear, performance apparel, fitness accessories, and equipment.

Built on Shopify, they drive massive traffic to their store through social media and influencer campaigns. Having a massive 30,000+ product catalog is usually a brand’s biggest strength—but for Supersports, it was actually a headache. 

With so many items to scroll through, it was hard to keep the mobile experience smooth while remaining personalized.

Supersports Vietnam’s goal was simple: convert high traffic into larger basket sizes. 

3 Main Challenges Supersports Vietnam Had to Solve

Supersports Vietnam didn’t have a problem getting people to their site, they had a problem getting them to buy more. Customers were coming in, buying a single item, and leaving. To fix this, the team had to tackle three major hurdles.

High Traffic, Flat AOV

Despite a consistent flow of visitors, Supersports Vietnam’s Average Order Value (AOV) was stuck. 

Shoppers would find the exact shoes or shirt they wanted, buy it, and leave. Because the site wasn’t automatically suggesting matching socks, bags, or gear, massive upsell opportunities were slipping through the cracks.

Without a system to automatically suggest matching items, the upsell opportunity disappeared with every single-item checkout. More catalog, more visitors, same basket size.

A 30,000+ SKU Catalog Too Big to Personalize

The core reason shoppers weren’t seeing complementary items was simple: the catalog was too large to manage manually.

With tens of thousands of products, the team couldn’t manually update the “You May Also Like” sections. 

Those sections were static, often outdated, and largely irrelevant to what a specific shopper was actually looking at. SuperSport needed an automated system that could surface the right product in real time — without requiring daily input from the team.

Slow and Clunky Mobile Browsing

Finally, there was a frontend friction problem. 

Shoppers in Vietnam and Thailand are accustomed to the seamless, continuous scroll of platforms like Shopee and TikTok Shop. Supersports Vietnam’s store, however, required shoppers to click through paginated results — a hard interruption to the browsing flow.

Worse, loading a large catalog on a single page caused noticeable lag. In a market driven by impulse discovery, that friction was killing sessions before an upsell could even be triggered.

How Supersports Vietnam Used Zotasell to Drive Growth

Supersports Vietnam didn’t need to rebuild their store to fix their problems. They added two focused tools on top of their existing Shopify infrastructure, and the results followed immediately.

AI-Powered Product Recommendations to Close the AOV Gap

Supersports Vietnam added Zotasell’s “Related Products” and “Frequently Bought Together” widgets directly to their product pages. The team didn’t have to manually link thousands of items.

Instead, Zotasell’s AI scanned the whole catalog to create smart, automatic suggestions in real time. The widgets also matched Supersports Vietnam’s fonts and colors automatically, making them look like a natural part of the store.

Vietnam and Thailand’s eCommerce shopper is heavily influenced by social proof and discovery. When a shopper arrives on a product page after seeing an influencer post, they’re already primed to buy. 

The window for an upsell is narrow but valuable. Zotasell’s AI seizes it instantly, skipping generic “bestsellers” to suggest exactly what similar customers bought together. The result is a recommendation that feels like advice, not advertising.

Lazy Load Infinite Scroll to Fix the Performance Bottleneck

Supersports Vietnam implemented Zotasell’s Lazy Load Infinite Scroll on their homepage to solve two problems at once: page performance and product discovery depth. 

Instead of loading the entire catalog on page render, the architecture loads products progressively as the user scrolls — reducing initial page load time while keeping the browsing session continuous.

On the other hand, forcing users to click “Next Page” buttons ruins their shopping momentum. Zotasell fixes both problems by loading new products smoothly and silently as the user scrolls down the page.

The performance lift directly made a massive difference to their ad spend. When a paid traffic click lands on a fast-loading, scroll-driven homepage, the session depth increases — more products seen, more opportunities for Zotasell’s AI to surface a relevant upsell trigger. 

Faster pages also improve quality scores in paid campaigns, compounding the media efficiency gain. This is an operational change that paid dividends across every channel simultaneously.

A Frictionless Mobile Experience

Before Zotasell, a shopper arriving via Instagram or a KOL link would land on a product page, convert (or not), and leave — with no meaningful pathway to discover adjacent products. 

The homepage browsing experience was limited by pagination and static layouts, and the “Related Products” section, if present, was rule-based and often irrelevant.

After applying Zotasell’s AI recommendations, that same shopper clicks an ad and smoothly scrolls through dozens of items without waiting for a page to load. 

When they click a pair of shoes, Zotasell instantly suggests the perfect matching gym bag based on real buyer data.

The impact was felt immediately in cart engagement. Shoppers began interacting more deeply with recommendations, exploring a wider range of items in each session. 

This increase in session quality created the behavioral foundation for larger baskets — and the AOV numbers followed.

The Results: 16.6% AOV Growth and More

The moment Supersports Vietnam turned on Zotasell, the impact was immediate. By simply guiding shoppers to the right products at the right time, they turned passive traffic into highly profitable shopping carts.

16.6% Higher Average Order Value (AOV)

In just 30 days, Supersports Vietnam’s AOV jumped by 16.6%. Customers tended to buy single items and started confidently adding complementary gear to their carts. 

For a high-volume retailer, a 16.6% AOV lift means every ad dollar spent on acquisition produces more revenue. The unit economics of the entire business improve without touching CAC.

A 12% Jump in Upsell Rates

In the first 7 days, the upsell rate reached 15.40%. Within the next 30 days, over 12.01% of all orders included at least one upsell item. That’s an incredible win for a store with over 30,000 products. 

The number proves Zotasell’s AI wasn’t just pushing random, annoying suggestions; it was showing items shoppers actually wanted to buy.

Zero Drop in Overall Conversions

When testing upsell tools, most merchants focus entirely on boosting Average Order Value (AOV). But Supersports Vietnam experienced an even bigger win: a jump in their overall conversion rate.

This happened because of how they set up Zotasell. By combining Related Products with Infinite Scroll, they focused on product discovery rather than just pushing bundles at checkout. As shoppers scrolled, the AI naturally revealed highly relevant items they would have otherwise completely missed.

The result? Shoppers completed more total transactions, driving up revenue across the entire store.

40% Faster Page Loads & Deeper Browsing

Lazy Load Infinite Scroll resolved SuperSport’s mobile performance issue immediately. Page load times improved by 40%, bounce rate dropped 18%, and shoppers viewed 25% more pages per session.

Supersports Vietnam could finally surface their full catalog to mobile shoppers without the friction that was previously ending sessions before they could convert.

Beyond the amazing number within just 30 days, the Supersports Vietnam team shared their truthful review on Shopify: 

“Super easy to use and set up. The UI is clean and intuitive, and it doesn’t affect my store’s loading speed at all. The team is super friendly and always ready to help, they even built some custom features based on my request. Absolutely love this app!”

FAQ: Scaling AOV for Shopify Stores with AI Upsell

Will adding an AI upsell app slow down my Shopify store?

No. In fact, you can improve speed and personalization at the same time. The key is choosing a lightweight app like Zotasell that renders new products smoothly as shoppers scroll, rather than trying to load thousands of SKUs all at once.

How long does it take to see results from AI upsell recommendations on Shopify?

Supersports Vietnam saw a measurable AOV lift within the first week. Most Shopify stores with sufficient traffic volume see early signals within 7–14 days of activation. The speed depends on traffic volume and the more sessions the AI ​​can analyze.

What is the highest-converting placement for upsells?

The Product Page (specifically the “Related Products” widget). While cart-page upsells are popular, Supersports Vietnam’s data revealed that product pages capture shoppers at their peak buying intent. 

When a buyer is looking at a specific item, an AI widget instantly showing the perfect matching accessory captures the impulse-buying moment.

Do I need AI recommendations, or can I manually link products?

If your catalog has more than 1,000 SKUs, manual linking is a growth bottleneck. Static “You May Also Like” rules quickly become stale and irrelevant. An AI-powered engine analyzes real-time shopper behavior to suggest what similar buyers actually purchased together. 

Conclusion

By letting AI guide their shoppers, Supersports Vietnam transformed passive browsing into a 16.6% AOV lift. If your store is struggling with small basket sizes, closing that gap is the fastest way to grow your business right now.
