Why Core Web Vitals Define SEO Success in 2025 — INP, TTFB & My Proven Optimization Tips (By Hridoy Chowdhury)

🚨 Google now ranks your performance, not just your content.

I’m Hridoy Chowdhury—SEO Consultant, Mentor, and Educator based in London—and if there’s one thing I want you to pay attention to this year, it’s this:

Core Web Vitals have evolved. INP and TTFB are now officially part of Google’s user experience ranking factors.

If your site feels slow or responds sluggishly, you're not just losing visitors—you're losing rankings.

Let me break it down 👇

⚙️ What Are Core Web Vitals in 2025?

Google’s updated Core Web Vitals now include four key performance metrics:

1. 🧠 INP – Interaction to Next Paint

→ Measures responsiveness after user clicks ✅ Aim: Less than 200ms

2. 🌐 TTFB – Time to First Byte

→ Measures server response delay ✅ Aim: Less than 0.8 seconds

3. 🖼️ LCP – Largest Contentful Paint

→ Measures how fast the main content loads ✅ Aim: Less than 2.5 seconds

4. 📦 CLS – Cumulative Layout Shift

→ Measures visual stability (no annoying jumps) ✅ Aim: Less than 0.1

These are real ranking signals—especially on mobile. If your site fails these, no content or keyword can save you.

🔧 How to Improve Your Core Web Vitals (Quick Wins)

As someone who optimizes 100+ sites every year, here are the go-to tactics we use in my agency:

✅ 1. Compress Images (Use WebP or AVIF)

Heavy PNGs = slow LCP. Use tools like Squoosh or TinyPNG.

✅ 2. Use a CDN (Content Delivery Network)

I recommend Cloudflare or BunnyCDN for global delivery.

✅ 3. Minify JavaScript & CSS

Reduce script execution delays. Use tools like UglifyJS or your caching plugin.

✅ 4. Set Font Display: Swap

Avoid invisible text while fonts load. This fixes CLS spikes.

✅ 5. Run Monthly Speed Audits

Use Google PageSpeed Insights or Lighthouse. Don’t guess—test.

🧠 Pro Tip from My Agency Workflow We include Core Web Vitals in every technical SEO audit. Clients love seeing tangible UX improvements—not just keyword data.

Because UX = SEO now.

📉 A Real Result:

After optimizing Core Web Vitals for a Shopify store:

• Bounce rate dropped by 19%

• Mobile LCP improved by 1.8 seconds

• 7 new keywords entered top 10 within 30 days

That’s not magic. That’s performance-based SEO done right.

You can use it for:

✅ Client education

✅ Internal audits

✅ Or just leveling up your own SEO knowledge
