Image-Heavy Pages Not Using Lazy Loading
Pages with many images load all at once without lazy loading, increasing initial load time and page weight.
By Seoxpert Editorial · Published
Why it matters
When all images load eagerly, especially those not immediately visible, it increases page load times and delays interactivity. This negatively affects Core Web Vitals, impacting both user experience and search rankings.
Impact
If unresolved, pages may load slowly, harming SEO performance and user satisfaction.
How it's detected
An automated crawler scans pages for multiple <img> tags and checks if images below the fold lack loading="lazy".
Common causes
- Images below the fold missing the loading="lazy" attribute
- Developers unaware of native lazy loading support
- Legacy code or frameworks that do not add lazy loading by default
- Copy-pasting image code without optimizing for performance
How to fix it
Code examples
Problem: All images load eagerly
<img src="photo1.jpg" alt="">
<img src="photo2.jpg" alt="">
<img src="photo3.jpg" alt="">Fix: Use lazy loading for images below the fold
<img src="photo1.jpg" alt=""> <!-- Above the fold -->
<img src="photo2.jpg" loading="lazy" alt=""> <!-- Below the fold -->
<img src="photo3.jpg" loading="lazy" alt=""> <!-- Below the fold -->FAQ
Should all images use loading="lazy"?
No, only images below the fold should use loading="lazy". Above-the-fold images should load eagerly for best performance.
How do I identify which images are below the fold?
Images not visible when the page first loads (without scrolling) are considered below the fold.
Will lazy loading affect SEO image indexing?
Modern search engines support lazy loading and will still index images with loading="lazy".
What if my framework handles images automatically?
Verify that your framework adds loading="lazy" to below-the-fold images, or configure it to do so.
