Improving Lighthouse Score with Lazy Loading and Code Splitting

User experience can be determined by the performance of your site in the current high pace digital world. Lighthouse is the tool which Google constantly uses, evaluating your performance in this. Lighthouse is an effective indicator that can positively or negatively affect the SEO of your site. As the pioneer website development company in Mumbai has come across clients who are oblivious of how minute backend design such as lazy loading and code splitting can completely boost their Lighthouse scores.

Why Lighthouse Score Matters for Your Business

The score of lighthouses influences not only the performance, but also accessibility, SEO, and general experience of the users. Such scores are a Google-recommended way to make sure your site is fast, active, and adaptable to any devices.

A poor Lighthouse score can:

• Cause bad Google ranking
• Increase the bounces rates
• Decrease the conversion rates
• Dented brand image

That is why other high-performing businesses select the development partners that will make every nut-and-bolt work, like the loading of the images or JavaScript processing.

Understanding Lazy Loading

What is Lazy Loading?

Lazy loading With lazy loading elements on the web page, such as images, videos or even an iframe, will not be loaded until they reach the top of the screen in the viewport. This will not wait to load content not even required in the front end and will reduce time taken to load dramatically.

For example:
Whereas all the images are loaded once a page is loaded, with lazy loading, only the first visible images are requested. Other ones are activated when someone is scrolling.

Benefits of Lazy Loading

1. Quicker First Page Speed - Users will view your site more quickly including when they are on a cell phone or a slow connection.
2. Better SEO- the performance is rewarded by search engines.
3. Lower bandwidth consumption - This can be of great use to users with low data packages.
4. Improved User Experience - Visitors move faster, which makes them happier.

We make sure we optimally use the lazy loading at CreativeWebo, primarily on media-intensive products listing or portfolio pages.

What is Code Splitting and How Does It Help?

Code Splitting Explained

Code splitting literally schedules your JavaScript bundles into small packages which are loaded only when required. It is like a novel divided into chapters--only that what a reader (or browser) needs is requested.

With more recent tools such as Webpack, Vite, or Next.js, the developer can separate the code in terms of route, function or component.

Impact on Lighthouse Score

• Faster Time to Interactive (TTI): It allows users not to wait until the big files are completely downloaded.
• Better first contentful paint (FCP): The pages seem usable much more quickly.
• Fewer Numbers Of JavaScript Blocking: Mobile users are particularly sensitive to it.

At CreativeWebo, we often adopt route-based code splitting in SPAs (Single Page Applications) such that our web pages are both fast and scalable.

 Real-Life Results from CreativeWebo

A real estate site with 100+ listing pages became one of our recent clients whose Lighthouse score on mobile was 42.
