Achieving 90+ page speed score using Google PageSpeed tool is a very challenging task, especially when you want to achieve it on both desktop and mobile. This is already known that mobile optimization is more difficult compared to desktop.
In this article, we will understand how high page speed score can be achieved for a WordPress website using practical optimization methods and real testing results.
What Is Core Web Vitals and Why It Matters
Core Web Vitals is basically a set of metrics which measure how users interact with your website. It checks page loading speed, visual stability, responsiveness and overall user experience.
These metrics decide how good your website performance is for real users. When Core Web Vitals passes, it means website is performing well in terms of speed and user interaction.
Real Performance Example (Before Optimization)
Before optimization, current website performance was:
- Desktop Score → 61 / 100
- Mobile Score → 41 / 100
Core Web Vitals → Failed on both Desktop and Mobile
This clearly shows website needed optimization improvement.
Target Performance After Optimization
After optimization, performance improved to:
- Desktop Score → Around 96 – 97
- Mobile Score → Around 85 – 90
Core Web Vitals → Passed on both Desktop and Mobile
Other performance factors also improved:
- Performance → 96
- Accessibility → 92
- Best Practices → 100
- SEO → 100
This shows strong overall optimization result.
Plugin Used For Speed Optimization
The plugin used for optimization is Airlift by BlogVault. This is a free WordPress plugin designed to improve website speed and performance.
This plugin works by analyzing website performance and optimizing multiple technical elements which slow down the website.
How The Plugin Works (Technical Level)
The plugin analyzes website like a real user. It checks:
- CSS files optimization
- JavaScript optimization
- Image compression and lazy loading
- Font loading optimization
- Viewport image preloading
- Caching level improvements
- Real user interaction simulation
It interacts with buttons, sliders, and elements to understand real loading behavior.
Step By Step Optimization Process
Step 1: Check Current Page Speed Score
Copy website URL and check performance using PageSpeed tool.
Step 2: Download Plugin
Download plugin and upload inside WordPress dashboard.
Step 3: Install and Activate Plugin
After activation, plugin automatically starts analyzing website.
Step 4: Wait For Optimization
Initial optimization usually completes in few minutes. Backend deep optimization can take longer time.
Real Result After Optimization
After first phase optimization:
- Mobile Performance → Around 90
- Desktop Performance → Around 97
- Core Web Vitals → Passed
This result was verified using official PageSpeed testing tool also.
Does Optimization Break Website Design?
This is very important concern. Many caching plugins improve speed but sometimes break website layout.
In this case, website design stayed same. No layout break happened. Website loading became faster without design change.
Why Website Speed Is Very Important
Website speed affects:
- Google ranking
- User experience
- Bounce rate
- Ad revenue potential
- Conversion rate
Slow website means users leave quickly.

Final Practical Observation
Plugin gave good optimization improvement. Real testing shows strong result improvement without breaking site design.
But final result always depends on:
- Hosting quality
- Theme coding quality
- Image sizes
- Server response time
Conclusion
Achieving 90+ PageSpeed score is difficult but possible with proper optimization strategy.
Speed optimization is not only plugin dependent. Full website structure also matters.
