How to Implement Lazy Loading on Shopify for Faster Page Loads

Lazy Loading

Lazy loading improves initial load times and reduces bandwidth usage by loading images and videos only when they enter the viewport.

Using Native Lazy Loading

Modern browsers support native lazy loading for images and iframes, providing an easy way to implement this feature without additional libraries.

Implementing Lazy Loading with JavaScript

Use JavaScript libraries like Lozad.js to enable lazy loading for images and iframes, ensuring compatibility with older browsers and offering more advanced features.

Lazy Loading Background Images

Dynamically load background images using JavaScript when they come into the viewport, as CSS does not natively support lazy loading for background images.

Testing and Debugging

Use tools like Google Lighthouse and PageSpeed Insights to test and ensure lazy loading is correctly implemented and effective.

Optimizing Lazy Load Thresholds

Adjust the threshold settings for lazy loading to preload content slightly before it enters the viewport, ensuring a smoother user experience and reducing the chance of users encountering unloaded content.
