// Performance
A technique that defers loading off-screen images and videos until the user scrolls near them. Reduces initial page weight and speeds up above-the-fold rendering. Implemented with the `loading='lazy'` attribute or Intersection Observer API.
Why it matters: Lazy Loading is one of the performance signals that shapes how search engines, AI tools, and real visitors experience your website. Getting it right removes friction, protects your rankings, and makes every other optimization work harder. Auditing it regularly is the fastest way to catch regressions before they cost you traffic or conversions.
