Most Shopify stores are slow because nobody owns it.
Speed isn't a one-time project. It's a margin problem that compounds every theme update, every app install, every quarter you don't measure it. We fix it – on a fixed price, with before/after benchmarks.

Why your Shopify store got slow.
It almost never starts with the theme. It starts the day you installed the third app. Then the fifth. Then the reviews app, the upsell app, the loyalty app, the analytics app. Each one ships 30–80kb of JavaScript onto every page load – most of it executing before your hero image renders.
Then your theme updates. The vendor changes how images load. A developer ships a quick fix on a Friday. A new pixel gets added for a campaign. Nobody benchmarks any of it. Six months later the mobile PageSpeed score is 28, the bounce rate is up, and nobody can point to what changed.
Speed dies in Shopify the same way every time: it's an organizational problem, not a code problem. There's nobody whose job it is to own it.

What we measure before touching code.
Field data first, then the storefront code path that produces it.
- LCP

- INP
- Main thread contention
- CLS
- Layout stability
- Apps
- JavaScript per page load
"Speed is a margin problem,
not a vanity score."
What we actually fix.
Core Web Vitals
LCP, CLS, INP – measured on real mobile traffic, not a lab test. We target the lift that moves conversion, not the score that wins a screenshot.
Mobile experience
70%+ of your US traffic is mobile. We optimize image delivery, font loading, and tap responsiveness for the device your customer is actually holding.
App stack bloat
We audit every third-party script, identify what's earning its weight, and defer or remove what isn't. Then we document it so it stays clean.
How we think about speed.
LCP, CLS, and INP aren't acronyms to memorize. They're business levers. A 0.5s LCP improvement on a $2M/yr store is real money. A CLS fix that stops the add-to-cart button from jumping is a conversion fix, not a UX fix.
We don't sell you a 100/100 PageSpeed score. We sell you the specific changes that move the metric your customer feels – and we measure both before and after, on the device and connection your actual buyers are using.
If your store doesn't actually need this work, we'll tell you. We'd rather lose a quote than ship a fix that doesn't move your number.

Performance Fix
A fixed-price engagement targeting Core Web Vitals, mobile speed, and third-party app bloat. Measurable in PageSpeed before and after.
Is this the right fit?
- $500K+/yr Shopify store
- Mobile-first traffic (70%+ mobile)
- Mobile PageSpeed below 50
- Conversion drop after a recent change
- 10+ third-party apps installed
- Core Web Vitals failing in Search Console
- Pre-launch or sub-$10K/mo store
- You want a redesign, not speed work
- Your real bottleneck is checkout, not speed
- You want a single PageSpeed screenshot
- You won't grant Shopify staff access
- You expect 100/100 on every page
