Website Speed Optimization That Actually Moves PageSpeed Scores
LCP under 2.5s, CLS under 0.1, INP green on mobile. We tune images, JS, CSS, fonts, and hosting until your site passes Core Web Vitals.
A Slow Site Costs You Rankings, Conversions, and Ad Quality Score
Google ranks fast sites higher. Customers bounce from slow sites. Google Ads gives slow sites a worse Quality Score, which costs you per click. Yet most sites take 5-8 seconds to load on mobile, fail Core Web Vitals, and lose money every day to speed.
The root causes are predictable: bloated images, render-blocking JS, unused CSS, slow fonts, third-party scripts (chat widgets, analytics, ad tags) loaded synchronously. Each has a fix, but it takes a methodical pass to do all of them.
We optimize speed end-to-end: images converted to WebP/AVIF, JS deferred and code-split, CSS critical-path inlined, fonts self-hosted with font-display: swap, third-party scripts loaded async. Real, measurable gains on PageSpeed Insights and Search Console.

Our Speed Optimization Process
- 01
Audit + Baseline
PageSpeed Insights, Lighthouse, WebPageTest, and Search Console Core Web Vitals data combined to baseline current performance and identify root causes.
- 02
Asset Optimization
Images converted to WebP/AVIF with responsive srcset, lazy loaded below the fold. CSS purged of unused styles, critical CSS inlined.
- 03
JS + Third-Party Tuning
JS code-split, deferred, lazy-loaded. Third-party scripts loaded async with proper sequencing. Chat widgets, analytics, and ad tags tuned.
- 04
Verify + Monitor
Re-test on PageSpeed Insights and real-user data via Search Console CrUX. Set up monitoring so regressions get caught early.
Engineered from day one.
Image Optimization
WebP/AVIF conversion, responsive srcset, lazy loading, hero image preloading.
CSS Critical Path
Critical CSS inlined, unused CSS purged, non-critical CSS deferred.
JS Code Splitting
Bundle splitting, route-level code splitting, defer + async on non-critical scripts.
Font Optimization
Self-hosted variable fonts, font-display: swap, preloaded above-the-fold fonts.
Third-Party Tuning
Chat widgets, analytics, ad tags loaded async with proper sequencing to protect LCP.
CDN + Hosting
CDN configured (Cloudflare, Vercel, Netlify), HTTP/3, Brotli, edge caching where possible.
