Shopify render priority and load order

When building a Shopify store, understanding how sections are rendered can help optimize your store’s performance and improve load times. Shopify follows a specific logic to determine which sections load first, and knowing this can help you structure your theme more efficiently.

In this post, we’ll explore:

• How Shopify prioritizes section rendering

• The difference between static and dynamic sections

• Best practices to optimize section loading

How Shopify Determines Section Load Order

Shopify renders sections in a specific order based on their type and placement in your theme.

Here’s how it works:

1. Static vs. Dynamic Sections

   Static Sections – Defined in theme files (e.g., header.liquid, footer.liquid) and always load in the same order.

   Dynamic Sections – Added via the theme editor (e.g., featured collection, slideshow) and can be reordered by merchants.

2. Rendering Priority Shopify follows this general load order:

   Critical Static Sections (head, body, theme.js)

   Above-the-Fold Static Sections (Header, announcement bar)

   Dynamic Sections in Order of Appearance (Top to bottom in theme editor)

   Below-the-Fold Static Sections (Footer)

   This ensures that the most important content (like headers and critical CSS/JS) loads first, improving perceived performance.

How to Optimize Section Loading

1. Minimize Render-Blocking Dynamic Sections

   Avoid too many dynamic sections above the fold.

   Use asynchronous or deferred loading for non-critical JS.

2. Use Static Sections for Key Elements

   Headers, footers, and critical UI elements should be static for faster rendering.

3. Lazy Load Non-Critical Sections

   Use the loading="lazy" attribute for images and media in lower sections.

4. Reduce Section Dependencies

   Avoid excessive Liquid logic in dynamic sections to prevent delays.

Final Thoughts

Understanding Shopify’s section rendering priority helps optimize store speed and user experience. By structuring your theme with static sections for critical elements and lazy-loading dynamic content, you can improve load times and boost conversions.
