Core Web Vitals for Nepal: How to Make Your Website Fast on Mobile Networks

Short answer: Core Web Vitals are Google's three user-experience metrics: Largest Contentful Paint (LCP) for loading, Interaction to Next Paint (INP) for responsiveness, and Cumulative Layout Shift (CLS) for visual stability. Google's "good" targets are LCP of 2.5 seconds or less, INP of 200 milliseconds or less, and CLS of 0.1 or less.

Why does speed matter more in Nepal?

Most visitors browse on phones, and connection quality varies by location and time. A page that feels fine on office broadband can be slow on a mobile network. Slow pages lose visitors before they see your content, and speed is also a ranking signal.

What do LCP, INP and CLS measure?

• LCP: how quickly the main content, usually a hero image or headline, appears.
• INP: how quickly the page responds when someone taps or clicks.
• CLS: how much the layout jumps while loading.

How do you improve LCP?

1. Compress images and serve modern formats such as WebP or AVIF.
2. Size images to the display, not the original photo.
3. Preload the main hero image and avoid lazy-loading it.
4. Use good hosting with caching and a CDN.
5. Render pages on the server so content arrives in the first response.

How do you improve INP?

• Remove unused JavaScript and heavy third-party scripts.
• Split large scripts and load non-critical ones later.
• Avoid long tasks that block the main thread.

How do you improve CLS?

• Always set width and height on images and embeds.
• Reserve space for banners, ads and pop-ups.
• Load web fonts with a fallback to prevent text jumping.

How do you measure your scores?

Use PageSpeed Insights, which shows real-user field data where available, plus Lighthouse and the Core Web Vitals report in Google Search Console. Test on a mid-range phone, not only on a fast laptop.
