“Anyone with an ecommerce website should be doing UX research. As part of a data-driven company, I don’t know what we would do without UserZoom and the confidence my team gets from UX insights”

Caroline Jensen

VP of Marketing, Whistle


It was a huge leap when Whistle evolved from a pet GPS company to a pet health company with no data to back up their hunch. To support the pivot in strategy with confident go-to-market decisions, the Marketing team first needed to address stagnant website conversions. 

“I don’t have the time or resources to waste on A/B testing. Sacrificing traffic and potential sales to observe marginal performance differences doesn’t make sense. I need to know what visitors think and why.” Caroline Jensen, VP of Marketing, Whistle


Vice President of Marketing Caroline Jensen and the team determined the most efficient approach would be research that paired visitors’ attitudes about their experience with their behavior on the site - UX research. 

With a limited research budget and no internal user experience (UX) research expertise, they found UserZoom - a UX insights system that brings together a multi-method research platform, participant recruiting capabilities, and a team of seasoned UX research experts who could provide strategic guidance and conduct studies on their behalf.

The UserZoom research team quickly revealed friction throughout the site, but the Wistle team needed deeper insights to make meaningful changes. Using a combination of surveys and video interviews with their target audience to get unfiltered reactions to the messaging and customer journey, they validated that health monitoring was the most valuable product feature for prospective customers. A pricing study uncovered that consumers were even willing to pay more for health-based plans.

“Of course when we surveyed customers who bought a GPS tracker they said that was the most important feature to them. But with UserZoom we engaged the universe of dog owners instead, and for the first time in the company we had data about where the market was heading - pet health.” Caroline Jensen, VP of Marketing, Whistle

After pinpointing what needed fixing across the website functionality and messaging, the UserZoom research experts then conducted a content audit and benchmarking study to establish a baseline for the most impactful conversion points in the customer journey. Armed with a reliable metric - UserZoom’s QXscore - Whistle could repeat this process to measure performance over time as they made changes based on research insights.


In less than a year after choosing UserZoom, the Whistle team applied their UX research insights to increase site conversion by an astounding 4,700%. 

But conversions are only the tip of the iceberg. The digital experience insights from the research helped the marketing team understand the interplay of visitor attitudes and behaviors. Which ultimately helped them overhaul the go-to-market strategy to position Whistle as a pet health company in an increasingly crowded market of GPS pet trackers.

In addition to the tremendous business gains, UserZoom makes Caroline and her team’s working lives easier by enabling them to challenge assumptions and apply data-driven decision-making to their work. As Caroline puts it, “The QXscore makes my life so much easier because nobody can argue with data''.
