Core Web Vitals Fixes That Skyrocketed Our Rankings in Just 7 Days
Speed. Stability. Interactivity. Nail these — and Google rewards you fast.
If you've ever wondered whether Core Web Vitals (CWV) actually impact your SEO rankings, here's a short answer: YES.
At Eternal Elevator, we put it to the test. We optimized our site for Google’s key CWV metrics — and in just 7 days, we saw a noticeable bump in rankings across multiple keywords (some jumping from Page 3 to Page 1).
Here’s exactly what we fixed, how we did it fast, and how you can do the same without breaking your site — or your budget.
🧠 What Are Core Web Vitals Again?
Google's CWV focuses on three major metrics that define the user experience:
Largest Contentful Paint (LCP) – How fast your main content loads
First Input Delay (FID) → now replaced by Interaction to Next Paint (INP) – How quickly your site responds to clicks
Cumulative Layout Shift (CLS) – How visually stable your layout is during loading
Google uses these as ranking signals — especially on mobile.
✅ What We Fixed (and How)
We started with a PageSpeed Insights audit and tackled the biggest pain points one by one.
1. Eliminated Render-Blocking Resources
We deferred non-critical JavaScript and used async tags for external scripts. Result? LCP improved from 4.5s to 2.1s.
2. Compressed & Lazy-Loaded Images
We converted large hero images to WebP and implemented lazy loading using the loading="lazy" attribute. Bonus: We used Cloudflare’s CDN to serve images faster based on user location.
3. Font Loading Optimization
We were using 3 Google Fonts — unnecessarily. We cut it down to 1 and used font-display: swap. This reduced our First Contentful Paint and visual delays.
4. Reduced CLS with Static Dimensions
We added explicit width and height attributes to images and iframes. No more layout shifts = CLS dropped from 0.28 to 0.02.
5. Fixed INP with Lightweight Interactivity
We replaced some bloated plugins with vanilla JS and ensured the main thread stayed light. Our Interaction to Next Paint dropped under 200ms.
📈 What Happened After 7 Days?

⚠️ Common Mistakes to Avoid
Relying too much on third-party scripts (chatbots, social feeds)
Overusing animations without fallbacks
Using sliders or video headers without optimization
Neglecting mobile experience in favor of desktop
💡 Final Takeaway
Google rewards real user experience. Improving your Core Web Vitals isn’t just about better scores — it’s about keeping users happy, engaged, and coming back.
The best part? Most fixes are not that technical — and they work fast. If you’re serious about SEO in 2025, CWV should be a non-negotiable part of your strategy.
