How can I reduce my page's initial load time using lazy loading?

Asked on Dec 05, 2025

Answer

Reducing your page's initial load time with lazy loading involves deferring the loading of non-critical resources, such as images and iframes, until they are needed. This technique helps improve performance by minimizing the amount of data that needs to be loaded upfront.

<!-- BEGIN COPY / PASTE -->
    <img src="image.jpg" loading="lazy" alt="Description of image">
    <!-- END COPY / PASTE -->

Additional Comment:

Use the "loading" attribute set to "lazy" on images and iframes to defer loading until they are near the viewport.
Ensure that critical images, such as those above the fold, are loaded normally to avoid layout shifts.
Consider using native lazy loading as it is supported in most modern browsers, reducing the need for additional JavaScript libraries.
Test your implementation using tools like Google Lighthouse to ensure lazy loading is effectively reducing load times.
