Lazy Loading is a performance technique that delays loading images, videos, or other resources until they are needed.
Example of Lazy Loading
Images far below an article’s opening can load as the reader approaches them. The main image visible immediately should be evaluated separately, and image dimensions should be reserved so later loading does not shift the text.
Why Lazy Loading matters
It matters because development decisions affect speed, security, scalability, tracking, SEO, and maintenance. A site that looks good but is fragile or hard to update can quietly hold back every marketing channel.
