One very simple and powerful way to make websites faster is by using lazy loading. This easy guide to lazy loading website elements will explain everything in simple steps so you can improve the loading time of any website. Lazy loading means the website will only load the images, videos or any external content when the user scrolls and actually needs it. This improves user experience, reduces server load and also helps in SEO. If your website is slow then visitors will leave within seconds, but with lazy loading you can keep them engaged easily.
What is Lazy Loading in Websites
Lazy loading is a method where images, videos or iframes are not loaded all at once when the page first opens. Instead, they load only when needed, for example when the visitor scrolls down. This improves loading speed and saves bandwidth. If you check any big news website or online shop, they use lazy loading to keep their huge pages fast and smooth.
Why Lazy Loading is Important
- Improves page loading speed instantly
- Reduces unnecessary use of bandwidth
- Makes website smooth on mobile data also
- Helps in ranking better on Google search
- Gives better user experience and keeps bounce rate low
How Lazy Loading Works
When any element like image is marked with a lazy loading attribute, it will not be downloaded until the user scrolls near it. This step by step management is done by browser or by JavaScript code. Modern browsers support simple HTML attribute loading='lazy' for images and iframes which makes the job very easy for developers.
Simple Lazy Loading Using HTML
If you want a very basic setup, then just add loading='lazy' to your image tag like this:
<img src='photo.jpg' loading='lazy' alt='sample image'>
By writing just this, the browser will wait until the user scrolls near the image before loading it. This is the easiest way to speed up your website without using any heavy scripts.
Lazy Loading for WordPress Websites
If you are using WordPress, then you will be happy to know that lazy loading is already available in the latest versions. Still you can improve with plugins like a3 Lazy Load or WP Rocket. With these plugins, you can fine tune how images, videos, and even background iframes are loaded. Many Indian bloggers and e-commerce store owners use such plugins to get better Google PageSpeed scores.
Lazy Loading for Custom Websites
If you are making your own website without CMS then you can use JavaScript libraries like Lozad.js or vanilla-lazyload. These are very light and easy to set up. You just need to mark your images with data attributes and the script handles the rest. Example:
<img data-src='photo.jpg' class='lazy' alt='pic'>
The JS code will replace data-src with real src only when needed. This method works smoothly on all browsers and helps when you have hundreds of images in a single page like product catalogues.
Examples of Lazy Loading in Real Businesses
A small furniture shop in Pune with many product photos can make its online store faster with lazy loading. Instead of forcing buyers to wait 10 seconds for all photos, only top part of the page will load first. As the customer scrolls, furniture images will appear. This keeps buyers happy and helps the shop owner sell more easily. Another example is a tuition teacher uploading lecture videos on his site. With lazy loading, only the first video shows instantly, others load later, saving bandwidth and cost.
Comparing Lazy Loading and Normal Loading
| Feature | Normal Loading | Lazy Loading |
| Initial Page Speed | Slow | Fast |
| Data Usage | High | Low |
| User Experience | Sometimes heavy | Smoother |
| Setup Effort | Default | Small fix needed |
| SEO Benefit | Not much | Improves performance signals |
SEO Benefits of Lazy Loading
Google has made it clear that website speed is a ranking factor. Lazy loading helps to reduce Largest Contentful Paint (LCP) and improves Core Web Vitals which are now very important for SEO. A website that loads fast will rank higher and convert better. So when you add lazy loading, you are not just saving bandwidth but also improving your digital marketing results instantly.
Lazy Loading and Mobile Experience
In India, many users access websites on mobile with 4G or sometimes weak internet. For them, lazy loading gives a big advantage. Instead of trying to load 50 product photos at once, their phones only download the first few. This means less waiting and longer engagement on your website. So if you want to grow digital sales, mobile-friendly performance using lazy loading is a must.
Lazy Loading for YouTube Videos
Embedding YouTube videos directly on your site can make pages very heavy. To fix this, you can use a trick: instead of loading the full YouTube player, just load a thumbnail image first. When the user clicks play, then only the video loads. This saves a lot of page size and makes website smooth. There are also plugins for WordPress and scripts available for custom websites for this method.
