Shopify Liquid Tutorial: Build a Custom Product Badge
TL;DR: To build a custom product badge, create a new metafield for your badge text and display it in your product template using a Liquid conditional statement. This method allows you to dynamically show labels like “New” or “Sale” based on specific product data without hardcoding values into your theme files.
Creating custom product badges enhances your store’s visual appeal and helps customers quickly identify key product attributes. This guide walks you through the process of implementing a dynamic badge system using Shopify’s Liquid templating language. By following these steps, you can add professional-looking labels that update automatically based on your inventory or product details.

Step 1: Define Your Badge Logic
First, determine the criteria for your badge. Common examples include displaying “Sold Out” when inventory is zero or “New” for products added within the last thirty days. You can use existing product attributes or create custom metafields via the Shopify admin. Metafields provide flexibility for custom data, such as a “featured” flag or a specific campaign label. Ensure your logic is clear before writing code to avoid confusion during implementation.
Step 2: Access Your Theme Files
Navigate to your Shopify admin dashboard and select “Online Store,” then click “Themes.” Find your current theme and click “Edit code.” You will need to modify the product card snippet, usually located in the `snippets` directory. Look for a file named `product-card.liquid` or `product-tile.liquid`. This file controls how products appear in collections and search results. Make a backup of this file before making any changes to prevent accidental data loss.
Step 3: Insert the Liquid Code
Inside the product card snippet, locate the area where product titles or images are displayed. Insert the following Liquid code block to conditionally render your badge. Replace `your_metafield_key` with the actual key of your metafield. For example, if you want to show “New” based on a metafield, use `{% if product.metafields.custom.new_product %}`. Wrap your badge text in a styled `span` tag to apply CSS classes for coloring and positioning. This ensures the badge appears consistently across your site.
Step 4: Style Your Badge
Liquid handles the logic, but CSS handles the look. Add a class name to your badge span, such as `product-badge`. Then, update your theme’s CSS file, typically found in the `assets` folder. Define styles for `.product-badge` to set background color, text color, padding, and font size. Use absolute positioning if you want the badge to overlay the product image. Test different colors to ensure high contrast and readability. A well-styled badge should be noticeable but not intrusive.
Step 5: Test and Deploy
Save your changes and preview your store. Check various collection pages to ensure the badge appears correctly on products that meet your criteria. Verify that products without the metafield value do not display the badge. Test on different devices to confirm responsiveness. If everything looks good, publish the theme. Monitor your store analytics to see if the new badges improve click-through rates or conversion. Regularly review your badge logic to keep it relevant and effective.
Tips for Success
Keep your badge text concise to avoid cluttering the product card. Limit the number of badges per product to prevent visual overload. Use consistent branding colors for all badges to maintain a cohesive store aesthetic. Consider using A/B testing to determine which badge styles resonate best with your audience. Finally, document your badge logic in your theme notes for future reference and easier maintenance by other developers.
