Core Web Vitals Tips to Improve Your Site’s Speed and Stability
Convenience and speed are not just perks but are often expectations. When it comes to your website, users won’t stick around for a sluggish, lumbering page to load, which is why top web development practices are essential.
But satisfying those expectations isn’t just about impressing your visitors; it’s also about impressing Google. Enter Core Web Vitals: Google’s user experience ranking signal, one that will have an immediate impact on your search rankings and, by extension, your business growth. In this blog, we dive into what Core Web Vitals are all about and explain why they’re now more important than ever for businesses in Singapore, plus what to do to get yours in peak shape.
What Are Core Web Vitals?
Core Web Vitals is a set of three measurable website performance aspects Google considers when deciding whether your site provides a pleasant browsing experience:
1. The Largest Contentful Paint (LCP)
This measure is the test for how fast the largest thing on your page — for example, a hero image, video, or big monolithic text block — can become visible to the user, which is vital in web design and development. A quick LCP means your site appears ready for users fast and doesn’t feel like a wait.
Goal: Under 2.5 seconds.
2. First Input Delay (FID)
Interactivity is crucial in website design to enhance the user experience. This aspect focuses on how quickly your site responds when a user tries to perform an action, such as clicking a link or tapping a menu, which is essential for mobile app development. High latencies here feel icky. It’s like pushing a lift button that doesn’t light up.
Goal: Under 100 milliseconds for optimal web development services.
3. Cumulative Layout Shift (CLS)
Suppose a user moves a layout element from its original position before the timeout. In that case, the user agent must update the element’s layout snapshot to correspond to the new position of the component.
This measures how much your content jumps around as the page loads, a key factor for web development services. Imagine trying to tap ‘Buy Now’ and inadvertently hitting ‘Cancel’ because a mobile app banner appeared.
Goal: To receive a CLS score < 0.1.
Why Singapore Businesses Should Care
Poor website performance stands out significantly, particularly when compared to the competition. This is why Core Web Vitals are so important to local brands and businesses:
Better Google Rankings: Google considers Core Web Vitals a ranking factor in the competitive landscape of web development companies in Singapore. The sites that pass are more likely to show up higher in search, which means that you outrank slower competitors.
Improved User Experience: Faster and more stable pages make visitors happier and encourage them to browse more for longer, increasing the chances of new clicks converting to customers.
Mobile-First Population: Singaporeans have one of the world’s highest smartphone penetrations. Most users are browsing over mobile networks, making speed and smoothness even more important.
Improved Brand Perception: A slow, jumpy website just isn’t professional, and it can undermine trust in your brand, no matter how excellent your products or services are, especially when compared to top web development companies.
How You Can Boost Core Web Vitals For Your Singapore Site
Not every case of improving your Core Web Vitals will mean a rebuild of your entire website. In many cases, making small changes can yield significant benefits, especially when working with a top web development agency. Here’s a handy way to begin your design services journey:
- Optimise & Compress Images: Heavy images are one of the major culprits for slow LCP. Leverage modern formats, like WebP, to optimise images without compromising quality and serve smaller-sized images based on screen size.
- Browser Caching and CDN: If you are using a third-party image on a page, you must also react to the browser caching and CDN requirements. One way to achieve this is using a Content Delivery Network (CDN), which supports website development by storing your website files on servers closer to your visitors. For Singapore, such an arrangement translates into a likelier ability to serve the wider domestic and regional audience, with expedited delivery times supported by robust web design and development from a leading agency in Singapore.
- Minify & Defer JavaScript: Too much or poorly written JavaScript can cause interactivity to slow down. Minimise your files to reduce their size and prioritise non-essential scripts to prevent blocking other content from loading.
- Define the Sized Media Dimensions for Media: Always specify the width and height for images, videos, and advertisements. This approach ensures that browsers reserve the proper space and content doesn’t jump around as things load.
- Monitor & Test Regularly: Keep tabs on your performance and catch new issues early with tools such as Google PageSpeed Insights, Lighthouse, and the Core Web Vitals report in Search Console.
