Switching from Constructor to Marqo was night and day. When we A/B tested Marqo, the impact was immediate and measurable - customers were finding products faster, and our Average Revenue Per User increased substantially.

Company Overview
SwimOutlet is America’s most popular online swim shop, trusted by professional athletes and recreational swimmers, with a catalog spanning performance swimwear, accessories, beachwear, and water-sport gear. Founded in 2000 and based in Campbell, California, SwimOutlet has become a leading force in North American swim retail.
The company offers more than 20,000 products from leading brands such as Speedo, TYR, Arena, and Nike Swim. With a mission to make every aquatic activity accessible, SwimOutlet serves competitive swimmers, triathletes, and beachgoers through its e-commerce platform and more than 10,000 dedicated Team Stores for swim clubs nationwide.
Challenges
After moving to Constructor, SwimOutlet aimed to strengthen its search experience and merchandising agility. Yet as the brand expanded, the team found it increasingly difficult to keep results relevant, intuitive, and aligned with shopper intent.
It’s marketing efficiency at scale.
With Marqo powering search, we’ve shifted from maintaining a sales channel to amplifying a growth engine. As acquisition costs rise, we’re investing where returns compound: our own site experience. Smarter search isn’t just conversion optimization anymore. It’s marketing efficiency at scale.

With over 20,000 SKUs and a highly detailed product assortment, key search signals and merchandising logic weren’t always reflected accurately, creating friction for shoppers and limiting performance insights.
Specific challenges included:
Constructor struggled with brand and product-name recognition, often surfacing incomplete or inaccurate results
Missing session metrics, category IDs, and readable collection names made it difficult to analyze performance or refine search logic
The team began searching for a solution that could interpret their catalog with nuance, give merchandisers real autonomy, and remove the need for engineering workarounds. A two-week A/B test with Marqo quickly showed how much more was possible.
Solution
Marqo was brought in to power smarter discovery, a unified, intent-driven search experience that connects customer behavior with business results.The rollout focused on powering both search and collections pages.
In a rapid implementation, the team:
Improved relevance by combining vector and keyword signals, enabling Marqo to understand brand and product-name intent with greater precision.
Restored merchandising control so boosts, buries, and featured products were respected end-to-end, and rules could now be targeted by specific attributes or categories.
Enhanced analytics visibility with deeper session tracking, clear category and collection identifiers, and real-time insights for performance tuning.
Unified infrastructure by running search and collections under a single vector-based architecture, eliminating fragmented configurations and reducing engineering overhead.
Optimized discovery experience by leveraging behavioral signals: clicks, add-to-carts, and purchases, to automatically surface high-performing items and improve shopper engagement.
This shift gave sneaker shoppers an intuitive way to search — by brand, style, release date, or model code — while significantly increasing engagement and driving higher cart values.
It feels like an extension of our own team.
What stood out with Marqo was how easy it is to work with their team. They move fast, they listen, and they understand the pace of ecommerce. Having direct access to their product and support teams means we can test ideas, get feedback, and see changes in real time. It feels like an extension of our own team.

projected annualized revenue impact
The shift to Marqo reshaped how KICKS CREW converts intent into revenue. Accurate model-number lookups, boosted new releases, and smarter ranking deliver exactly what customers expect — and more. Instead of losing shoppers to irrelevant results or buried inventory, KICKS CREW now drives bigger baskets and stronger loyalty from its core search experience.
What This Means
With search and collections now unified under Marqo, SwimOutlet is continuing to build on its success by expanding Marqo’s capabilities across the site experience.
The platform has become a foundation for discovery, adaptable, scalable, and aligned with how customers actually shop.
We’ve seen what happens when discovery truly works, higher ROI, deeper engagement, and a clearer picture of what drives our customers. That’s the kind of progress every marketing team should aim for.
