Frequently Asked Questions
What's the simplest lazy loading method?
Add loading='lazy' attribute to img and iframe tags. It's supported in all modern browsers and requires no JavaScript. The generator provides this code.
Should I lazy load all images?
No - don't lazy load above-the-fold images that are immediately visible. Those should load normally. Lazy load images that require scrolling to see.
How does lazy loading affect SEO?
Native lazy loading is SEO-friendly - search engines can still index images. JavaScript solutions should include noscript fallbacks for crawlers.
