Core Web Vitals tuning.
100/100 speed and zero layout shift.
We eliminate Cumulative Layout Shift, drop Largest Contentful Paint under one second, and tune Interaction to Next Paint. Turn slow websites into instant conversion engines.
140+ Speed Audits
Slow mobile loads over 3.5 seconds and jumping page elements hurt Google rankings and cause visitors to abandon carts.
We remove unused code, inline critical styles, compress images, and reserve layout slots for instant rendering.
100/100 Google mobile scores, server response under 50 milliseconds, zero visual shift, and higher conversions.
Performance numbers.
Strict technical standards measured across all client deployments.

Largest Contentful Paint
Zero visual jumping
Interaction to Next Paint
What we build.
Contentful Paint
We accelerate your largest visual elements so hero text and banners display in under one second.
- Critical CSS inlining for fast rendering
- WebP image formats with responsive sizing
- Preloading priority hero assets at edge
Layout Stability
We lock page elements in place during loading to stop frustrating jumps while users read or click.
- Fixed aspect ratio dimensions on images
- Font fallback metric overrides via CSS
- Reserved space for banners and ads
Interaction Response
We free up browser processing so buttons, menus, and search bars respond immediately to user touch.
- Splitting long JavaScript tasks into small chunks
- Removing unused tracker code from templates
- Delaying background scripts until idle moments
Image Compression
We convert bulky PNG and JPEG graphics into modern formats to cut total page weight by 80 percent.
- Automated WebP conversions across all media
- Responsive picture tags for phone screens
- Lossless compression preserving crisp detail
Script Cleanup
We eliminate heavy JavaScript libraries and render blocking stylesheets that stall page rendering.
- Deferring non-critical scripts to end of load
- Stripping unused framework CSS and rules
- Cleaning duplicate font files and tag managers
Memory Caching
We configure lightning fast server memory storage to serve dynamic HTML pages in milliseconds.
- Redis object caching for database queries
- Cloudflare edge caching rules configured
- Fast HTTP response times under 50ms
How we compare.
Direct developer code optimization versus temporary caching plugins.
Feature Architecture spec | Temporary Plugins Caching plugins | FixrWeb Code Edits Direct developer tuning |
|---|---|---|
Root Cause Fix Underlying issue | Saves static HTML copies over bloated scripts | Deletes unused scripts, rewrites CSS, and tunes database |
Mobile 4G Speed Cellular loading | Scores drop on mobile phones when cache misses | Consistent 95 to 100 mobile scores on real devices |
Layout Stability Visual shift | Content jumps as fonts and late banners pop in | Exact container slots guarantee zero visual shift |
E-Commerce Safety Cart dynamics | Risk of caching user shopping carts and forms | Clean cart isolation with fast Redis memory cache |
Third-Party Scripts Tag management | Loads all tracking tags at once on page startup | Defers analytics until after initial interaction |
Maintenance Update stability | Updates often break themes and conflict with code | Permanent clean code baseline that stays fast |
