Optimizing Your Webpage with Lazy Loading

The download speed of a website is critical for brand engagement. According to some research, the average internet user expects a website to load in two seconds or less. If a user has to wait to access your page’s content, it’s likely that they’re already browsing other sites.

Almost all of the contents of a webpage are downloaded in one go when you open it. Because a new visitor is unlikely to read the entire article, this results in bandwidth and memory waste. There is a workaround for this: lazy loading.

Lazy loading is a website speed optimization technique that improves a webpage’s performance while also lengthening its loading time. Not only that, but it also helps you turn your user into a customer.

The data on a web page is cached and rendered once it is opened. There is no assurance, however, that the visitor will stay long enough to read the complete text. Some users are prone to skimming the page, reading only the top content, and then leaving.

So, what exactly is “lazy loading”? It’s the content on the page loading slowly. Because there is no guarantee that the user will stay on the site long enough to read the content at the bottom of the page, this is an alternative to bulk loading.

A crucial rendering path is the time it takes for a user to reach the page’s largest contentful paint (LCP). The load speed of a page is determined by how long it takes for the main content to load. LCP is a crucial component of user experience and speed.

Google introduced core web vitals in May 2020, which serve as a baseline signal for evaluating how a user will interact with a webpage. They aid SERP ranks and website performance because they are part of the algorithm. Since the release of core web vitals, LCP has become increasingly relevant.

A major part of fundamental web vitals is how a user interacts with a web page. The user will leave the page if the critical rendering time increases. It’s possible that lazy loading will have an effect here. If you delay the loading of non-critical elements or content that appears at the bottom of the page, your user is more likely to stay on the page.

How does Lazy Loading Work?

Web pages include images and videos in addition to written material. Because images and videos are typically larger in size, they take longer to load on the page. It’s not just the user’s internet speed that affects how quickly a website loads; it’s also the website’s speed.

After the site has been cached and displayed, lazy loading occurs. This allows the user to get to the information they need quickly. It’s also quicker because the site won’t take as long to load. You must conserve bandwidth and memory if your bottom content is image or video-heavy.

When you visit a website, the content that appears at the top of the page is the actual content. The bottom, on the other hand, would have placeholder content. The contents of the website will only load once you scroll beyond the top with lazy loading. As a result, the placeholder material will only be replaced by the genuine text once you reach the bottom of the page.

When implementing lazy loading, there are a few factors to bear in mind.

Positioning matters: If you’re using lazy loading on your website, make sure it’s positioned correctly. The user will see the top material first, so it’s critical to keep them interested in the page’s content. Because the top of the fold loads first, it’s critical to display interesting statistics and information here to keep the user interested and generate leads.

Because images and video files are larger than content files, they take the longest to load on a webpage. You can make your page load faster by optimizing these images and videos. You can do things like lazy load images, use a compression tool to compress your images, and host your videos on external sites.

Impact of Lazy Loading in SEO

For fast page loading, lazy loading is the best option. Pages load rapidly, allowing the user to get to the content more quickly. When trying to optimise for SEO, however, it can have an impact on search engine ranks.

When a page takes a long time to load, search engines are unable to crawl the full page, and slow loading has an impact on this crawling. This does not, however, imply that your page’s content will be ignored. There will just be a delay, and the rankings will not appear at the top of the page.

Lazy loading can be achieved by ensuring that the most important stuff is displayed first. You can also give links to the information that is loaded slowly. So, even if the complete material isn’t loaded, the user can still get the information they need by following the links provided.

How to Know if my Site Needs Lazy Loading

Lazy loading isn’t required for every website. Running your site through a speed performance tool is one approach to see if it needs lazy loading. You can use speed performance tools to get recommendations on how to implement slow loading.

Lazy loading might help you improve the speed of your website by optimizing the items on it. Reducing redirects, deleting render-blocking JavaScript, optimizing movies and graphics, and so on are all examples of this. There’s a chance you’ll get a recommendation for ‘defer off-screen image.’ If you come across this, you’ll need to use picture lazy loading on your site.
You can also use the core web vitals report in the search console to see if your site has LCP difficulties.

This will tell you if any of your website’s pages are having problems loading. It does not mean that you will have to use lazy loading if some pages take longer than 4 seconds to load. This can be used as a ‘tip-off’ tool to determine which portions of your site are slow, as well as other suggestions.

Contact a developer before deciding to create lazy loading on your own. While it may appear to be an easy task, it is not. Most website hosts either encourage or provide third-party plugins for their lazy loading implementation.

This will cost you some money, but it will help you generate revenue and increase brand engagement in the long run.

Lazy loading can be incredibly advantageous if you’re running an SEO strategy.

Improves Page Load Time: A balance must be struck between allowing consumers to access data and conserving bandwidth. The user can quickly get the data thanks to lazy loading. The user does not need to scroll to the bottom if the information they are looking for is right at the top of the page. This ensures that no bandwidth is wasted. It’s also crucial to provide a live user experience. If the content is immediately accessible at the top, they are more likely to return to your page.

Faster Content Connection: The load time will be longer if you try to load the complete website in one go. As a result, consumers will have to wait longer for the information they require. One of the benefits of lazy loading is that it allows the user to connect to the material more quickly. They may see the content as soon as the top of the page loads. They only see the material farther below after they start scrolling. They are able to read and participate in the content they require. If the user does not want to scroll to the bottom of the page, this saves bandwidth for the website.

Longer Visit Time: It is critical for any developing organization to retain and engage its consumer base. Customers learn more about your brand when they spend longer time on your website. Customers are more likely to stay on a website when information is readily available, resulting in new business leads. A quick website also indicates that the user will return to the page in the future for more information. This familiarity with the brand aids in the conversion of leads.

Make the Most of Your Resources: Not every user will go through the site in detail. Some people will only look at the top of the page, while others will look at every page. Lazy loading aids in catering to the amount of information required by the audience. With lazy loading, the top of the page is loaded first. Data will be loaded once the user begins scrolling to the bottom. This aids in resource optimization. You save bandwidth, data, and time on the browser by doing so.


Finally, using lazy loading into your SEO plan improves the user experience and speeds up the delivery of website content. It speeds up loading times, earns income, and boosts brand awareness. If you wish to use lazy loading, an SEO service can assist you with finding the correct diagnostic tool and implementing picture lazy loading, among other things.
