In this WordPress Speed Optimization case study, I will show you exactly how I took my slow site from a Red score of 65 to a Green score of 87+ using free tools.
I recently tackled a frustrating issue with my site, Tipzz N Trickz. My Google PageSpeed Insights mobile score was stuck at 65 (Red Zone), and the “Largest Contentful Paint” (LCP) was a painful 4.5 seconds.
I knew that to get AdSense approval, my user experience had to be flawless. Nobody waits 4 seconds for a site to load.
After applying a few smart tweaks, my score jumped to 87+ (Green Zone), and the site now loads like a rocket 🚀. This post is a personal breakdown of my WordPress Speed Optimization journey — no fluff, just results.
Step 1: The Heavy Logo Mistake (The Big Win)
My logo file (Tipzz-N-Trickz-Logo.png) was 192 KB — way too heavy for mobile data. This was the main culprit killing my LCP score.
What I did:
- Downloaded my logo.
- Used TinyPNG (a free online tool) to compress it down to 11 KB.
- Re-uploaded the optimized logo to my site header.
Result: This instantly fixed the LCP issue and shaved off nearly 2 seconds from the load time. If you have a slow site, check your logo size first!
Step 2: CSS & Google Fonts Fix
My site was making too many separate requests to the server. I used the Autoptimize plugin to clean up my CSS and font loading.
Settings I enabled:
- ✅ Aggregate CSS-files (Found in the JS, CSS & HTML tab).
- ✅ Combine and link Google Fonts in head (Note: I found this setting under the “Extra” tab in Autoptimize).
Why it works: Combining stylesheets reduces HTTP requests. Loading fonts in the head prevents the text from being invisible or flashing while the page loads.
Step 3: Next-Gen Image Conversion
Old PNG and JPG images were slowing things down. Google loves “Next-Gen” formats like WebP because they are much smaller in size.
The Fix:
- I installed the Converter for Media plugin.
- I clicked “Start Bulk Optimization” to auto-convert all my existing images to WebP format.
Result: Images now load faster and use less bandwidth — a big win for mobile users.
Step 4: Fixing Cache Policy
Google flagged my site for having a “7-day cache policy.” It wanted static assets (like images) to be cached for longer to save data for repeat visitors.
Solution:
- Installed WP Fastest Cache (Free version).
- Enabled the “Browser Caching” checkbox.
- This forces the server to set the expiration time to 1 year instead of 7 days.
Step 5: Removing JavaScript Bloat
I discovered that Microsoft Clarity was injecting heavy JavaScript (clarity.js) that took over 26KB of bandwidth.
Action Taken: I deactivated and deleted the Clarity plugin. While heatmaps are useful, right now, speed and AdSense approval are my top priorities.
Result: JavaScript execution time dropped, and my site became noticeably snappy on mobile devices.
Conclusion
This WordPress Speed Optimization case study proves that small changes can make a big difference. From compressing a logo to tweaking cache settings, I went from a sluggish 65 to a solid 87+ on mobile — all without spending a rupee on premium plugins.
