The mental picture most merchants have of a theme test is impossible on Shopify. There is one published theme, and Shopify says so in the enum itself: the main role is the currently published theme and there can only be one at any time. Nothing publishes two and splits traffic between them. What these apps do instead is alter sections and layout on the single live theme, per visitor, which is why the good ones talk about rendering without a flicker and the weaker ones flash the original design before swapping it.

Price testing has a harder ceiling. A variant carries one price, and the only interface that overrides what a cart line actually costs is limited to the top plan. Below that, a test can vary what is discounted from the order or the shipping, not the unit price a shopper sees attached to the product. Checkout itself is not variable either for most stores, since extensions on the information, shipping and payment steps are documented as available only on the top plan.

And the measurement is entirely the app's. Shopify's own visit data records the landing page, a referral code and a marketing event, with no field for which variant somebody saw. Whichever tool you pick owns the assignment, the attribution and the arithmetic, so its statistics are as important as its editor.

What to look for in a CRO app

What it can actually vary on your plan
Write the test you want first: a different hero, a different product page layout, a different price, something at checkout. Then check it against the limits above, because half the ideas merchants bring to this category need the top plan and the listings rarely say so.
How the swap is rendered
A visitor who sees the control for half a second before the variant loads has polluted your test and had a worse experience. Ask how the assignment happens and watch a real test on a slow connection.
Which number decides
Conversion rate alone can pick the worse variant if the winner sells cheaper things. Revenue per visitor, average order value and, where it can be fed in, margin are the measures that answer the actual question. Most listings here offer at least one of them.
When it will call a result
Ask what the tool does about significance and duration: whether it warns you off reading a test on day two, whether it accounts for weekly cycles, and whether you can see the raw counts rather than a verdict.
What a price test does to everything else
Different shoppers seeing different prices touches feeds, ads, comparison sites and returning customers. Decide in advance who is excluded, how long the test runs and what a customer is told if they notice.

What does the Built for Shopify badge mean?

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time. When comparing similar apps, preferring ones with the badge is a safe default. Learn more about the Built for Shopify badge →
