What We Optimize

From image pipelines to server config — we cover every layer of your stack to deliver measurable speed improvements.

Core Web Vitals Audit

Full Lighthouse + CrUX analysis. We identify exactly what drags your LCP, FID, and CLS into the red — large images, render-blocking scripts, layout shifts.

Speed Optimization

Image conversion to next-gen formats (WebP/AVIF), code minification, lazy loading, critical CSS inlining, and tree-shaking unused JavaScript.

CDN & Infrastructure Tuning

Configure Cloudflare, AWS CloudFront, or Vercel Edge for global speed. Smart caching rules, Brotli compression, and HTTP/3 for sub-second TTFB.

Theme & Code Refactoring

Remove bloated apps and unused CSS/JS. Refactor Liquid, React, or PHP to load only what each page needs. Lean code = fast execution.

Mobile Performance

70% of eCommerce traffic is mobile. We eliminate long tasks, optimize touch targets, and ensure your store is butter-smooth on every device.

Asset Optimization

Automated image pipelines, font subsetting, sprite sheets, and preloading critical resources. Every kilobyte counts for mobile shoppers.

Why Speed Matters

Every second of delay costs you customers and revenue. Here is what the data says.

53% of users leave

if a mobile page takes longer than 3 seconds to load. Every second of delay costs you real customers.

$2.6 billion lost annually

across eCommerce due to slow websites. Speed directly correlates with revenue — faster stores sell more.

Google rewards speed

Core Web Vitals are a confirmed ranking factor. Faster pages rank higher, get more organic traffic, and lower your CAC.

70% higher conversion

for pages that load in under 2 seconds vs. pages that load in 5+ seconds. Speed is the cheapest CRO lever you have.

Cart abandonment drops

A 1-second improvement in load time can increase conversions by up to 7%. Fewer abandoned carts, more completed orders.

Better crawl efficiency

Google crawls fast sites more thoroughly. More indexed pages means more keywords ranking and more entry points for shoppers.

How We Work

01

Deep audit

We run comprehensive PageSpeed, Lighthouse, and real-user monitoring tests. You get a detailed report showing exactly what slows your store down and by how much.

02

Prioritized fix plan

We rank every issue by impact vs. effort. High-impact, quick wins first — you see results within days, not months.

03

Implementation

Our engineers fix everything — image optimization, code refactoring, caching, CDN setup — on a staging environment first. No surprises on your live store.

04

Verify & monitor

We verify improvements with before/after benchmarks, set up ongoing monitoring, and provide a report you can share with your team.

Our Speed Guarantee

If we don't improve your PageSpeed score within 7 days, you don't pay. No contracts, no risk — just measurable results.
