How to verify your A/B test is working

Learn how to confirm your test is working successfully as your configuration.

Verify your ABConvert test is working using preview URLs, browser console checks, Chrome extension, and unlisted products for safe QA testing.

Method 1: Use the view links in the analytics page

After launching the test, you can click the test by going to the “Analytics” page.

  • Price Test and Content Test in “View test groups”

    Price Test and Content Test in “View test groups”

  • Shipping Test, URL Redirect Test, Template Test, Theme Test in “Summary”

    Shipping Test, URL Redirect Test, Template Test, Theme Test in “Summary”

Method 2: Add ?preview=0 or ?preview=1 in the URL

Preview URLs let you see specific test variants without affecting your analytics data.


How to preview different variants

Add preview parameters to your product or page URL:

- '?preview=0' – Shows the original (control)

- '?preview=1' – Shows test variant 1

- '?preview=2' – Shows test variant 2 (if applicable)

Example:

- Original: 'yourstore.myshopify.com/products/product-name?preview=0'

- Variant 1: 'yourstore.myshopify.com/products/product-name?preview=1'

Note:

Preview parameters work for most test types. If your test includes targeting rules (geographic location, customer tags, device type), you may need to match those conditions to see the variant.

Method 3: Use the ABConvert Helper Chrome extension

ABConvert Helper is a Chrome extension that lets you inspect, debug, and manually test your ABConvert A/B tests directly in the browser. This guide covers everything you can do with it.

How to install the extension

Download the ABConvert Helper extension from the Chrome Web Store

(for those who has installed it already, please update to use the latest version)

How to use the extension

  1. Visit your Shopify store's website in chrome browser

  2. Look for the new ABConvert icon in your browser toolbar (top-right corner) and click it

  3. The extension side panel will open and automatically scans the page

  4. If it shows ABCONVERT ACTIVE, it means you have active tests in your store website now, which you can continue checking details with following tabs

Tests tab

The Tests tab lists all active ABConvert tests detected on the current page. Each card shows the test type, version (original version v1.0 or new beta version v2.0), and experiment ID.

Each test card includes test configuration details to check, and force variant function to test.

View configuration

Click Configuration on any card to expand the full test details:

- Audience targeting — country filter, device filter, visitor type

- Traffic allocation — what percentage of visitors enter the test

- Test groups — control vs. variant traffic split

- Test-specific settings — prices, redirect URLs, DOM mutations, etc.

Force Variant

Force Variant lets you jump directly into a specific test group without waiting for random assignment.

1. Click Force Variant on any test card to expand the controls

2. Select a group — Control or Variant

3. If the test has a country filter, choose a country from the dropdown

4. Click Apply & Reload

The extension reloads the page with the correct URL parameters automatically. To return to normal random assignment, click Clear & Reload.

Components tab

The Components tab shows raw detection results — what scripts, theme embedded apps, web pixels, and cart attributes are present on the page. Use this to verify detection is working correctly or to check what cart attributes have been assigned to your session.

Controls tab

Use this tab to reload, clear cacher, or override local seed or country in your browser for further testing.

FAQ

Why can't I see the test variant of my test?

We only display one variant to each visitor. If you want to check different variants, you can either:

  1. Use an incognito browser to visit your store and close the browser entirely before revisiting.

  2. Use ?preview=0 or ?preview=1 in your URL; it will display the assigned variant. (0 to original, 1=test group 1, etc)​

The ABConvert Helper shows errors. What should I do?

Take a screenshot of the extension results, note your test type, and contact support team. The technical information helps our team diagnose issues quickly.
