How SwimOutlet Boosted Revenue and ATC Rates with Marqo

Company Overview

SwimOutlet is one of America’s most recognized online swim retailers, trusted by professional athletes and recreational swimmers alike. Founded in 2000 and headquartered in Campbell, California, the company offers a broad catalog spanning performance swimwear, accessories, beachwear, and water-sport gear, serving customers across North America.

Why SwimOutlet Evaluated Marqo

As SwimOutlet’s catalog and customer expectations continued to grow, the team identified an opportunity to further evolve their on-site search and product discovery experience. With increasingly nuanced shopper intent and a growing long-tail of queries, SwimOutlet sought a solution that could better interpret context, understand domain-specific language, and adapt relevance dynamically.

The goal was to modernize discovery while reducing reliance on manual tuning and static rules.

Challenges

Managing discovery across more than 20,000 SKUs placed increasing demands on SwimOutlet’s search experience. The team prioritized sharper relevance, smoother navigation, and faster iteration cycles.

They needed a system capable of understanding their catalog at a deeper semantic level while maintaining flexibility and operational efficiency.

It’s marketing efficiency at scale.

As acquisition costs climb, the smartest investment we've made is in our own site experience. Marqo changed the way customers search. This isn't just conversion optimization anymore — it's marketing efficiency at scale.

Solution

Marqo's pixel was installed on the SwimOutlet website to continuously track clicks, add to cart events, purchases and general user behaviour. This user interaction data collection allows Marqo to understand and optimize for both general and user specific behaviour.

This pixel data was ingested by Marqo's platform, which utilized this data to train a custom LLM and continuously improve search relevance. Through this mechanism, Marqo was able to deliver intent-aware relevance that adapts to SwimOutlet’s products and attributes across both search and collections without relying on generic models or manual setup.

SwimOutlet deployed Marqo for search and browse use-cases for their AA/BB test, has since expanded to using Marqo to power recommendations after going live with 100% of traffic on search and browse.

What stood out most with Marqo is how easy they are to work with. They move fast, they listen, and they understand the pace we operate at. Having direct access to their product and support teams means we can test ideas, get feedback instantly, and see changes in real time. It genuinely feels like they're an extension of our team.
