Whoosh's numbers, and what each one means
Every store starts on a 50/50 test for its first few weeks, about a month: half the shoppers get Whoosh and half do not. Once the result is clear, it moves to 90/10, keeping 10% of shoppers as a control group so the lift stays measured. Whoosh's own figures come from these tests on client stores.

In their own words
What merchants and agencies say about Whoosh.
“The closest thing to a silver bullet in ecomm that we’ve come across. By only improving site speed, our conversion rates lifted 10% overnight.”
Drew Mansur Co-founder at TileCloud “Whoosh are obsessed with speed, and proof is in the pudding. Our load times dropped from 4.8 seconds to 1.35 seconds.”
Jaryd Leibbrandt Co-founder at Nakie “Whoosh delivered exactly what it promised: faster pages, better scores, and zero effort from our dev team. It’s one of the easiest wins we’ve had.”
Charles Hurtebize Founder at Lepicerie Agency (Veja & Gramicci AU) “I was skeptical about the revenue recovery claims, but the numbers don’t lie. We’re saving thousands of sessions every month that we previously lost to bounce. Pretty impressive for a speed optimization tool.”

Questions about results
How quickly can I see results after installing Whoosh?
It depends on the Whoosh plan you’ve chosen. Smart App Loading can impact key performance metrics such as LCP and INP immediately (note: PageSpeed Insights reflects the last 28 days of data, so don’t expect immediate changes there). AI Page Preloading relies on real user data to build an understanding of common navigation patterns, so timing for results significantly depends on the traffic your website gets. Typically, we see the effects within the first two weeks.
How do you measure the revenue Whoosh recovers?
With an A/B test on your own store. Every store starts on a 50/50 test for its first few weeks: half your shoppers get Whoosh and half don’t, and your dashboard compares conversion and revenue between the two groups. The difference is the revenue Whoosh recovers. Once the result is clear, the split moves to 90/10, keeping 10% of shoppers as a control group so the lift stays measured.
