How to Show "Units Sold" on Shopify Product Pages (No App Needed)

Adding a “Units Sold” label on your Shopify product page is a great way to boost trust and drive conversions. When customers see that others are buying, it creates a sense of urgency and social proof — making them more likely to click "Add to Cart." 🙌

In this post, we'll show you how to create a dynamic "units sold" display using Shopify’s native features and XynoThemes — no app required.

🔧 Step 1: Add a Custom Metafield for Units Sold

• Go to your Shopify Admin > Settings > Custom data > Products.
• Click Add definition.
• Set the Name to something like “units_sold”.  it must be exactly “units_sold” for the theme to recognize it correctly. If you use a different name, it will not work.
  Choose the Type:
  → Select Interger .
• Save the metafield definition. After savings, your meta look like this 

✏️ Step 2: Add Units Sold Data to Products

• Now go to Products > [Your Product]
  Scroll down to the Metafields section.
  Enter the number of units sold under your custom field.
  Click Save.

🧩 Step 3: Add the "Units sold" Block

• From your Shopify admin, go to Online Store > Themes.
• Click Customize on the theme you’re editing.
• Navigate to Products > choose Default Product (or any product template you’re using).
• In the theme editor, click “+ Add block” inside the product section.
• Choose the block called  'Unit solds' . This block shows both "unit solds" and "inventory status"

And see the results:
