Since 2021, Google officially uses page experience signals — including Core Web Vitals — as a ranking factor. For businesses in India competing for local search traffic, this matters more than most people realise.
What Are Core Web Vitals?
Core Web Vitals are three specific metrics Google uses to measure how a real user experiences your website: LCP — Largest Contentful Paint How long until the largest visible element (usually a hero image or heading) finishes loading.
- ✅ Good: under 2.5 seconds
- ⚠️ Needs improvement: 2.5–4.0 seconds
- ❌ Poor: over 4.0 seconds
INP — Interaction to Next Paint (replaced FID in 2024) How responsive is your page when a user clicks a button or taps a menu? Measures the delay between a user action and the visual response.
- ✅ Good: under 200ms
- ⚠️ Needs improvement: 200–500ms
- ❌ Poor: over 500ms
CLS — Cumulative Layout Shift Does your page jump around while loading? Elements that move unexpectedly (ads loading, fonts swapping, images without dimensions) create a poor experience.
- ✅ Good: under 0.1
- ⚠️ Needs improvement: 0.1–0.25
- ❌ Poor: over 0.25
Why This Matters Specifically in India
Average mobile internet speeds in India range from 15–45 Mbps on 4G, with significant variation by city. Jabalpur, Bhopal, Indore, and other tier-2 cities often see lower average speeds than metros. A website that scores “Good” in Google’s lab (simulated fast connection) may score “Poor” for real Indian users on actual mobile networks. Google measures from real user data (Chrome User Experience Report) — not just lab simulations. This means: your competitor’s site may rank higher than yours purely because it loads faster on Indian 4G connections, even if your content is better.
How to Measure Your Score
PageSpeed Insights (best starting point): Go to pagespeed.web.dev, enter your URL, and run on mobile. This gives you both lab data and real-world field data from Indian Chrome users if you have enough traffic. Google Search Console: GSC → Core Web Vitals report shows which pages are “Poor”, “Needs Improvement”, or “Good” based on real users visiting your site. Chrome DevTools: Open Chrome, press F12 → Lighthouse tab → run an analysis. Use “Mobile” preset with simulated throttling to see what Indian mobile users experience.
The Top Fixes for LCP (Most Common Problem)
LCP is the most impactful metric and the most commonly failing one. Fix 1: Preload your hero image
<!-- Add to your <head> section -->
<link rel="preload" as="image"
href="/images/hero.webp"
imagesrcset="/images/hero-480w.webp 480w, /images/hero.webp 1200w"
imagesizes="(max-width: 640px) 480px, 1200px">Fix 2: Convert images to WebP format WebP images are typically 30–50% smaller than JPEG at the same quality. Convert using Squoosh.app (free, browser-based) or cwebp command line tool.
cwebp -q 82 input.jpg -o output.webpFix 3: Use responsive images with srcset
<img src="/images/hero.webp"
srcset="/images/hero-480w.webp 480w,
/images/hero-800w.webp 800w,
/images/hero.webp 1200w"
sizes="(max-width: 640px) 480px, (max-width: 1024px) 800px, 1200px"
alt="Softcrony Technologies"
loading="eager"
fetchpriority="high">Mobile users load the 480w version (~30KB), not the full 1200w version (~120KB). On Indian 4G, this saves 2–3 seconds of load time. Fix 4: Enable gzip on your server Add to your .htaccess file:
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/css
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/json
</IfModule>Fix 5: Remove render-blocking CSS and JS Load non-critical CSS asynchronously:
<link rel="preload" href="/style.css" as="style"
onload="this.onload=null;this.rel='stylesheet'">Add defer to non-critical scripts:
<script src="/app.js" defer></script>The Top Fixes for CLS (Layout Shift)
Always specify image dimensions:
<!-- Bad: causes layout shift while image loads -->
<img src="photo.jpg" alt="Team">
<!-- Good: reserves space before image loads -->
<img src="photo.jpg" alt="Team" width="800" height="600">Self-host or preload Google Fonts: Google Fonts load asynchronously and cause text to reflow when they arrive (FOUT). Fix with font-display: swap or self-host the font files. Reserve space for ads: If you run ads, set a minimum height on ad containers so the page doesn’t jump when ads load.
Realistic Improvement Timeline
Based on our experience optimising Indian business websites:
- Week 1: Convert images to WebP + add srcset → typically improves LCP by 1–2 seconds
- Week 1: Enable gzip in .htaccess → saves 60–70% on CSS/JS transfer size
- Week 2: Add image dimensions everywhere → usually fixes CLS completely
- Month 1: Google’s algorithms update your ranking based on new field data
What Score Do You Actually Need?
You don’t need a perfect 100. A Lighthouse score above 80 on mobile and all three Core Web Vitals in the “Good” range is sufficient to have no performance-based ranking penalty. Focus on getting out of “Poor” first. Getting from “Poor” to “Needs Improvement” often produces visible ranking improvements. Getting from “Needs Improvement” to “Good” is a bonus. — Softcrony offers free website performance audits for businesses in Jabalpur and across India.
