Google: Why Lazy Loading Can Delay Largest Contentful Paint (LCP)​

On Google’s podcast, Martin Splitt explains how default lazy loading can delay LCP, why some libraries hinder indexing, and how to verify fixes.

• Google warns against lazy-loading above-the-fold images.
• It can delay LCP and feel jarring for visitors.
• Verify in Search Console by checking the rendered HTML.

“If you are using lazy loading on an image that is immediately visible, that is most likely going to have an impact on your largest contentful paint. It’s like almost guaranteed.”

Funny enough we actually experienced this previously no matter what we done with the server settings the LCP was still apparently sucking, we ditched lazy load for only category pages and results improved.

Personally these kind of metric piss me off a little when fibre is the fast become the norm and more so when google is the self declared internet police.

Well, lazy loading above fold has always been stupid whatever Google says.

Lazy load above the fold also frequently contributes to CLS js

Don’t.
