The Wake-Up Call
You might think your company website is fast—until you run it through Google PageSpeed Insights and get a score that makes your morning coffee taste bitter. That’s exactly what happened to us at eMazzanti Technologies. Our website scored a humbling 45 on mobile. After three weeks of relentless optimization, troubleshooting JavaScript, and more performance audits than we care to admit, we hit 92 on mobile and 98 on desktop. The lessons we learned can help you skip the frustration and head straight for those coveted green scores.
The Image Nightmare
Images are often the biggest culprits behind sluggish websites. We found massive, high-res images used for tiny thumbnails—an all too common mistake. Switching to the WebP format, setting proper image sizes, and implementing lazy loading transformed our homepage. Load times dropped by three seconds. At one point, we discovered a background pattern image that was larger than the rest of the page combined. Replacing a 2MB PNG with a 2KB SVG made a night-and-day difference. Sometimes, the simplest fixes are the most effective.
- Image Optimization: Use next-gen formats and size images appropriately for every device.
- Lazy Loading: Only load images when they enter the viewport.

The JavaScript Jungle
JavaScript can easily become a tangled mess. We found multiple jQuery versions, unused animation libraries, and abandoned tracking scripts. By merging and minifying files, removing unnecessary scripts, and deferring third-party code, we slashed our Time to Interactive by nearly 60%. Ruthless pruning is essential—if a script isn’t vital, it shouldn’t load.
- Audit Regularly: Remove outdated or unused scripts for leaner, faster pages.
- Defer Loading: Load non-essential scripts after the main content.

The CSS Cleanup
Bloated CSS is like digital cholesterol—slowing everything down. We trimmed duplicate rules, deleted unused styles, and implemented critical CSS for above-the-fold content. Instead of loading massive frameworks for minimal use, we replaced them with custom code. Our First Contentful Paint time halved as a result.
- Critical CSS: Inline styles needed for immediate content, defer the rest.
- Custom Over Frameworks: Use only what you need to keep style sheets light.
The Caching Revolution
Caching is your website’s memory—why do the same work twice? We set up browser caching, implemented a service worker for offline access, and configured smart server-side caching. Repeat visitors saw pages load almost instantly. Don’t be surprised if someone on your team doesn’t see updates—incognito mode bypasses cache!
- Browser Caching: Store static assets locally for faster reloads.
- Server-Side Caching: Reduce backend processing for popular pages.

The Mobile-First Reality
If your site isn’t designed mobile-first, you’re missing the mark. We prioritized mobile design, stripped unnecessary animations, and simplified complex interactions. The mobile PageSpeed score jumped 20 points from these changes alone. Once mobile is optimized, desktop usually follows naturally.
- Prioritize Mobile: Optimize images, layouts, and scripts for mobile devices first.
- Simplify Interactions: Remove hover effects and animations that don’t translate to touch.
The Server Situation
Sometimes, slowdowns aren’t your fault—they’re your server’s. We implemented a CDN, optimized server response times, and enabled GZIP compression. Our server was in California, but most users were in Europe. CDN positioning solved latency issues overnight, making the site feel snappier worldwide.
- CDN Deployment: Distribute content closer to your users for faster load times.
- Compression: Use GZIP or Brotli to shrink files before delivery.

The Font Fiasco
Web fonts can be beautiful—and a big drag on performance. We were loading five weights of a custom font but only used two. By optimizing font loading, using font-display swap, and subsetting to only needed characters, we eliminated unnecessary delays. No need to load Cyrillic for an English-only site!
- Subset Fonts: Only include characters your site uses.
- Font-Display Swap: Prevent invisible text while fonts load.
The Optimization Future
Web optimization is an ongoing journey. We’re experimenting with new formats like AVIF, adopting module/nomodule JavaScript patterns, and leveraging native lazy loading. The landscape keeps evolving, and so do our techniques. Staying ahead means continuous learning and adaptation.
