Testing Bundle Widget Placement on Shopify Product Pages

Above the Fold vs. Below the Fold

The most important placement decision for a bundle widget is whether it appears above or below the fold on your product page. Above the fold means the widget is visible without scrolling, guaranteeing that every visitor sees the bundle offer. Below the fold means only visitors who scroll see it. On mobile, where most Shopify traffic arrives, the fold is lower on the page and a significant proportion of visitors never scroll past the add-to-cart button. Testing above-fold placement typically produces higher bundle engagement.

Placement Relative to the Add-to-Cart Button

The bundle widget placed near the add-to-cart button benefits from the customer's buying intent at that moment. When a customer is evaluating whether to click add to cart, they are in an active purchase mindset. A bundle offer visible at this moment has the best chance of being considered seriously. Placement below the add-to-cart button or after the product description is a natural secondary position that still captures engaged visitors who read through the page.

Mobile-Specific Placement Considerations

Mobile product pages have less vertical space before the fold than desktop. On mobile, any element placed before the bundle widget reduces the proportion of visitors who see the bundle offer. Review your product page layout specifically on mobile and identify whether the bundle widget is visible without scrolling. If it is not, consider simplifying or compressing the elements above it to move the widget higher. See the mobile optimisation guide for more.

Running the Placement Test

Test your current widget position for two weeks, then move it to an alternative position and measure the bundle engagement rate (clicks on bundle products) and conversion rate for the following two weeks. Compare the results and implement the higher-performing placement permanently. Use Bundle MixMatch for bundle management and install for free.
