Slow stores lose 40% of sales.
We fix the code, not just the symptoms.
Most speed "experts" install another optimizer app that makes your store slower. We dive directly into your Liquid templates, vendor scripts, and render trees to deliver lightning-fast paint times, zero layout shifts, and measurable conversion lifts.
The Engineering Sprint
What actually happens during
your speed optimization.
No band-aids. We systematically deconstruct and refactor the front-end bottlenecks that drag down mobile user experience and checkout completion.
01 · ASSET & FONT TUNING
Next-Gen Media & Local Fonts
We convert oversized raster assets to modern WebP formats, eliminate layout shifts with explicit aspect ratios, and replace external render-blocking Google Font chains with self-hosted, preloaded variable fonts.
02 · SCRIPT RESCHEDULING
App Bloat & Pixel Decoupling
Klaviyo, Gorgias, reviews, and ad pixels freeze mobile CPUs. We implement intelligent script scheduling that delays non-critical tags until user engagement, keeping tracking 100% accurate while freeing the main thread.
03 · CRITICAL CSS & DOM
Eliminating Render-Blocking Chains
We extract and inline critical above-the-fold CSS styles, prune unused vendor styles, and streamline bloated DOM nesting so mobile browsers paint your hero section in under 1.2 seconds.
04 · LAYOUT SHIFT ERADICATION
CLS Zeroing & Fluid Typography
Unexpected jumps during page load destroy user trust and fail Google's Core Web Vitals. We reserve space for banners, popups, and dynamic app widgets so the layout remains rock-solid.
05 · ZERO DOWNTIME TESTING
Staged QA & Device Testing
Every change is implemented in an isolated theme environment. We audit your checkout, cart drawers, currency converters, and subscription flows on physical iOS and Android devices before anything touches production.
06 · HANDOVER & MONITORING
Full Autonomy & Long-Term Maintenance
We provide a video walkthrough of every change and a checklist for your marketing team on how to upload future banners and install new apps without hurting your hard-earned 90+ score.
Proven Authority
We don't preach speed.
We engineer it daily.
We recently audited and optimized Klickspell itself from the low 70s to a flawless 98/100 on Mobile and 99/100 on Desktop with 0ms Total Blocking Time and zero third-party dependencies.
The exact same principles applied to California skincare brand Jaxon Lane and modern DTC brands are deployed to supercharge your store.
Engineering Integrity
Real Core Web Vitals vs.
Cheap "90+ Score" Cloaking Scams
A rampant issue on freelance marketplaces is speed "optimizers" who trick synthetic test bots rather than fixing actual store latency. Here is how to tell the difference:
What Cheap "90+ Speed" Services Do
- Bot Cloaking: Injects scripts that detect Google Lighthouse bots and disable Klaviyo, Meta Pixel, and apps exclusively during synthetic tests.
- Zero Real Speed: Real shoppers on 4G mobile devices still wait 5 to 8 seconds for pages to render.
- Broken Tracking: Often causes severe tracking drop-offs, misattributed revenue, and broken Meta/TikTok pixel events.
- CrUX Failure: Fails Google's real-user field data (Chrome UX Report), failing search ranking boosts.
The Klickspell Architectural Standard
- Direct Code Refactoring: Purges orphaned "zombie" Liquid snippets and dead asset requests left by uninstalled apps.
- Conditional Scheduling: Loads review widgets and chat widgets only on pages and interaction moments when needed.
- 100% Tracking Integrity: All marketing pixels and analytics fire accurately without blocking critical initial paint.
- Passed Real-User CrUX: Delivers sub-second LCP and near-zero TBT for actual human customers on real mobile devices.
