Lazy loading delays loading images until they’re about to enter the viewport, improving initial page load times. Here’s how to implement it:
- WordPress 6.0+ includes native lazy loading support – no plugin needed for basic functionality
- Add loading=’lazy’ attribute to image tags automatically
- Use the a3 Lazy Load plugin for advanced features
For optimal implementation:
- Prioritize above-the-fold images by excluding them from lazy loading
- Use proper image dimensions to prevent layout shifts
- Consider using low-resolution placeholders
The a3 Lazy Load plugin offers additional features like custom threshold distances and support for iframes and videos.
