A/B testing
Test every personalization, prove every gain
Ecommerce A/B testing tells you whether a change made money or just looked good. In Skubl, every personalized experience can run against a holdout group of shoppers who see your default store, so you can see the real lift in conversion rate and revenue per visitor.
Testing is built into Skubl’s ecommerce personalization, not bolted on.

The problem
Personalization without a control group is guesswork
Revenue went up after you launched a new experience. Was it the experience, the season or the sale that started the same week? Without a holdout, you can’t tell.
- 01
Correlation dressed up as results
“Revenue influenced” counts sales that would have happened anyway.
- 02
Tests that stop too early
A good first week is called a win before the result is reliable.
- 03
Separate testing tools
A split testing tool that can’t see your personalization can’t measure it.
How Skubl solves it
How ecommerce A/B testing works in Skubl
01
Holdout groups by default
A share of shoppers sees your default experience, so every result is measured against a real control.
02
Multivariate testing
Test several variants of an experience at once and see which combination performs best.
03
Shopify A/B testing without theme copies
Tests run inside your live theme, without duplicating it.
04
AI-assisted allocation
Optionally shift traffic toward winning variants while a test runs.
Statistical significance, in plain language
What the numbers on a test result actually mean.
- Lift
- How much better or worse the variant did than the control, such as +4% conversion rate.
- Confidence interval
- The range the true lift probably falls in. If the range includes zero, you haven’t proven a difference yet.
- Statistical significance
- A sign the difference is unlikely to be chance. It says nothing about whether the lift is big enough to matter.
- When to stop
- Decide the sample size before you start, and run for at least one or two full weekly cycles.
Multivariate testing vs. split testing
- Split test
- Two or more complete versions of an experience, with traffic divided between them.
- Multivariate testing
- Several elements changed at once, such as headline, image and offer, to find the best combination. Needs more traffic.
- Holdout
- A group that sees no personalization at all, used to measure the total value of personalizing.
