Want to run A/B tests on your Shopify store? You’ll need to add a small Plerdy tracking code to your website. Don’t worry — this takes only a few minutes and requires no coding skills.
Follow these steps.
Step 1. Copy the A/B Test Code in Plerdy
- Log in to your Plerdy account.
- Go to A/B Testing in the Conversions section.
- Click “Add A/B Code.”
- A pop-up window will appear — copy the A/B testing code shown there.
You’ll paste this code into Shopify in the next step.
Step 2. Open Your Shopify Theme Code
- Log in to your Shopify Admin panel.
- In the left menu, go to:
Online Store → Themes - Find your active theme.
- Click the three dots (•••) next to it.
- Choose Edit code.
You’re now inside your theme files.
Step 3. Paste the Plerdy Code
Where you add the code depends on where you want A/B testing to work.
Option A — Add the code to ALL pages (recommended)
- In the left file list, open:
Layout → theme.liquid - Scroll down to the bottom of the file.
- Find the closing tag: </body>
- Paste the Plerdy A/B code right BEFORE this tag.
- Click Save (top right corner).
Done! The code is now installed sitewide.
Option B — Add the code only to specific pages
If you want A/B testing only on certain pages, insert the code before </body> inside the relevant template files instead of theme.liquid.
Step 4. Check That the Code Is Installed Correctly
Now let’s make sure everything works.
- Open your website in a new browser tab.
- Go back to Plerdy → A/B Testing (Conversions).
- Click “Add A/B Code.”
- In the window that opens, click “Check installation.”
You’ll see a status message confirming whether the code is detected.
That’s It 🎉
Once the status is confirmed, you can start creating A/B tests in Plerdy and improving your Shopify store’s conversion rate based on real user behavior.
