# Troubleshooting Content Experiments and FAQs

How to read content experiment results, fixes for common editor and delivery problems in Elevate A/B Testing, and answers to frequent questions.

***

### Reading the results

For what each metric means and how a winner is decided, see the reports and statistical significance documentation. Two things are specific to content experiments.

**Small changes produce small effects.** A restyled button will not move revenue per visitor in a week. If the change was narrow, judge it on a narrow metric and accept that the answer may be a tie.

**A multi element variation is one result, not several.** If you changed the headline, the button, and the section order, a win tells you the combination worked. Treat it as a decision to ship, not a lesson about headlines.

### The changes do not appear on the storefront

**Likely cause.** The theme extension is not enabled, or the page you are viewing is not one you edited.

**Fix.** Confirm the extension is on, then confirm you are on the right page and in the right variation.

### The change appears, then reverts

**Likely cause.** The theme rerenders the section after load and overwrites the change. Common on elements that update when a variant is selected.

**Fix.** Check the element in Preview after interacting with the page, not just on load. If the theme rebuilds that element, target a stable parent or use custom CSS instead of an element level change.

### The element I selected was not the one I meant

**Likely cause.** Clicking usually selects the innermost element, often the text rather than its container.

**Fix.** Use the Layers panel to select the parent explicitly. The editor labels the selected element with its tag and class, which tells you what you have.

### The layout breaks on mobile only

**Likely cause.** The change was made in desktop view and the mobile layout has different constraints.

**Fix.** Switch the editor to mobile and adjust. Check every variation at both widths before launching.

### Hiding an element broke the page

**Likely cause.** You hid a container rather than the element inside it, so everything it held disappeared with it.

**Fix.** Undo, select the specific element in the Layers panel, and hide that instead.

### Edited text is not saving

**Likely cause.** Content changes require **Apply**. Style changes do not.

**Fix.** Select **Apply** under the content editor after making a text change.

### The variation is slower than the control

**Likely cause.** Custom JavaScript or CSS added to the variation, or a large added image.

**Fix.** Reduce what the code does on load and compress added images. A speed difference is a second change and it will affect your result.

### FAQs

**Do I need the theme extension?** Yes. Changes are applied on the page, so the extension is required and the experiment cannot launch without it.

**Do I need to duplicate anything?** No. Your original page is saved automatically as the control and nothing in your theme is duplicated.

**How many variations can I run?** Up to five including your control.

**Can one experiment cover more than one page?** Yes. Use the page search in the editor to move to another page and make changes there within the same experiment.

**Can I add code as well as visual changes?** Yes. The editor offers **Custom JavaScript** and **Custom CSS** per variation. If the code is the point rather than a finishing touch, a custom code experiment is the better fit.

**Can I add elements that are not on the page already?** Yes. Text, headings, images, and containers.

**Should I use content or page testing?** Content edits elements on the page you already have. Page serves a different template. If you would be duplicating a template to change one element, use content.

**Which Shopify plans support it?** All of them.
