What is Lazy Load?
Lazy Loading is a feature that aims to make a page faster by postponing the loading of images, scripts, embeds and stylesheets.
How does Lazy Load work in practice?
Lazy Load causes the site to load as a whole, leaving out only deferred resources, which are loaded after the website loads.
How does Lazy Load technically work?
When you open a website, the Browser creates the DOM (Document Object Model) of the page leaving out deferred objects such as images, videos, scripts, and stylesheets.
After the page is fully loaded, deferred objects are loaded along the scroll.
If you are still using CDN to distribute your content, it is likely that the user will not even notice that the features have been delayed, which further contributes to the browsing experience.
Why use Lazy Load?
Many users slow down a site in a hurry, which increases the bounce rate, so with this in mind, Google implemented Core Web Vitals to encourage sites to go faster and provide a better experience for users. p>
