WordPress Lazy Loading Guide

Lazy loading postpones non-critical media until it is closer to the viewport.

Where it helps

Pages with many below-the-fold images or embedded media can avoid transferring everything during initial render.

Do not lazy-load the hero blindly

If the primary above-the-fold image becomes the LCP element, delaying it can hurt the metric you are trying to improve.

Native and plugin behavior

Modern browsers and WordPress can provide native lazy-loading behavior, while performance plugins may add additional media handling.

Test visual stability

Reserve dimensions for media so content does not jump as assets load, and verify galleries, sliders and embeds still work.
