When a test wins, we make it part of the site
Steadyrack run conversion experiments to find what actually moves the needle, across three regional stores. Plenty of teams stop there: a test wins, and it just keeps running inside the testing tool, month after month, a third-party script deciding the outcome on every page load. It works, but it is rented, and it is slower than it needs to be.
What we did
We do the step after the win. When a test proves itself, we take the winning version and build it properly into the theme, so it becomes permanent site code Steadyrack own, and the testing tool can be switched off for that experiment. A collection layout that splits a product into its size options with their own cards. A product-page block that updates to show which size suits which use as the customer chooses. Proven in testing, then hardcoded across all three stores.
The result
The wins are permanent, they load faster because they are native theme code rather than a script fetched on every visit, and they belong to Steadyrack outright. The testing tool goes back to doing what it is for: finding the next win, not hosting the last one forever.
What to take from it
A winning experiment is only worth what you do with it. Leaving it live in the testing tool indefinitely means paying every month for a result you could own outright, and serving it slower than a customer deserves. When a test wins, make it part of the actual site.
