Lazy loading defers the loading of non-essential resources to improve page speed and user experience.
Lazy Loading is a design pattern that postpones the loading of non-essential resources at the point of page load. Instead of loading all images and videos simultaneously, lazy loading allows these elements to load only when they are about to enter the viewport. This technique significantly speeds up initial page load times, enhancing user experience and improving SEO metrics.
By implementing lazy loading, websites can decrease their initial server requests, leading to faster page speeds. Tools like Web.dev provide guidelines on how to implement this effectively. This is particularly beneficial for sites with many images, such as portfolios or e-commerce platforms.
Lazy loading helps improve page speed, which is a critical factor for SEO. Faster loading pages lead to better user retention and can positively impact search rankings.
For example, a blog that has implemented lazy loading for images will only load images as the user scrolls down the page, rather than all at once, resulting in a smoother and faster browsing experience.
