Lazy loading is a technique that delays loading non-essential images until they are needed. This improves page load times, saves bandwidth, and enhances user experience, especially on slower connections.
What is lazy loading?
Lazy loading is a method to defer loading of images until they are about to appear in the viewport.
How does lazy loading help with page load times?
Lazy loading reduces the amount of content loaded initially, making pages load faster.

1. Use the Native Lazy Loading Attribute
Use the `loading='lazy'` attribute for native browser support to simplify image loading without JavaScript.
2. Implement Lazy Loading for Off-Screen Images
Ensure images outside of the viewport are lazy-loaded to reduce initial load time.
3. Prioritize Above-the-Fold Content
Ensure important images load immediately to avoid blocking visible content from appearing.
4. Use Intersection Observer for Better Control
Use the Intersection Observer API to fine-tune when and how images load in the user's viewport.
5. Test Your Lazy Loading Implementation
Use tools like Google PageSpeed Insights to test lazy loading and optimize the implementation.
Lazy loading is a powerful technique to improve page load times and performance. Properly implementing lazy loading will make your site faster and more user-friendly, enhancing both user experience and SEO.
