Results from Shopify orders
An order counts only when Shopify's own record ties it to the visitor's group.
Profit per visitor
Add your cost of goods and every test reads profit per visitor beside revenue and conversion.
No flicker
The group is decided before the page paints, so shoppers never see the control first.
Audience targeting
Run a test for mobile visitors, new visitors, one country or one traffic source.

Which stores can run checkout tests?
