Services / Improve what’s live / Speed
Make the store faster — so the traffic you already have can convert.
We find what's dragging load time — theme code, apps, images — then ship the fixes. Core Web Vitals up. Bounce down. Shoppers stay.
Shopify Plus Partner
Shoppers don't wait. Neither should the page.
A slow store doesn't feel like a technical problem. It feels like people bouncing, ads getting more expensive, and mobile never converting.
Symptom
"Mobile is most of our traffic — and the slowest experience"
Most Shopify traffic is on a phone. If the first paint is late, the add-to-cart never happens. Desktop scores hide the leak.
Symptom
"We keep adding apps and the store got heavier"
Reviews, popups, upsells, pixels — each one seemed small. Together they block render, fight each other, and quietly tax every session.
Symptom
"Google says we're slow and ads feel more expensive"
Poor Core Web Vitals hurt ranking and paid efficiency. You're paying for clicks that never see a usable page.
Our speed process
Find the drag, fix the real causes, prove the lift.
We don't chase a Lighthouse screenshot. We measure field and lab data, then change the theme, apps and assets that actually block shoppers.
01
Measure & diagnose
Waterfall, Core Web Vitals, theme weight, app scripts and image delivery — mapped to homepage, collections, PDP and cart.
02
Fix the biggest leaks
Lean Liquid, deferred JS, image and font strategy, app cleanup. Highest impact first — so the store feels faster early in the project.
03
Prove it held
Re-test lab and field metrics. You get before/after on the templates that matter — not a generic “we optimized the site.”
What we fix
The weight Shopify stores actually carry.
Theme code
Bloated Liquid, unused CSS and render-blocking JS are the usual suspects — especially after years of stacked agencies.
Images & media
Photography-heavy catalogs don't have to be slow. Delivery, sizing and lazy-load decide whether the PDP feels instant.
Apps & scripts
Every app injects something. We keep what earns its keep, remove what doesn't, and stop duplicate pixels from fighting.
Core Web Vitals
LCP, INP and CLS — lab scores and real-user data. We optimize the templates Google and shoppers actually hit.
What we examine
Every layer between the click and a usable page.
Homepage & landing LCP
Hero media, fonts and above-the-fold scripts — the first impression paid traffic actually waits for.
Collection & filter weight
Grids, swatches and filtering that don't freeze the page when someone starts shopping.
Product page media
Galleries, videos and variant images sized and sequenced so the buy button appears on time.
Cart & checkout path
Drawers, upsells and third-party checkout extras that shouldn't stall the last step.
Mobile field performance
Real devices and real networks — not only a desktop lab score that looks fine in the office.
App & pixel inventory
What's loading, when, and whether it still earns a place on the storefront.
What you get
A faster store — with proof, not a score screenshot
Shipped code, cleaner apps, and numbers you can show the team — on the templates that actually sell.
- Faster first paint
- Shoppers see a usable page sooner — especially on mobile, where most sessions live
- Stronger Core Web Vitals
- LCP, INP and CLS treated as conversion work, not a SEO side quest
- Less wasted ad spend
- Clicks land on a page that's ready — so paid traffic has a chance to buy
- A theme you can still run
- Leaner code without locking the editor or stripping the brand

How it works
From baseline to a store that feels instant.
-
01Day 1
Kickoff & baseline
Access, known pain, and a snapshot of lab plus field metrics on homepage, collection, PDP and cart — so every fix has a scoreboard.
-
02Week 1
Diagnosis
Theme, apps, images and third-party scripts ranked by impact. You see what to keep, what to cut, and what to rewrite.
-
03Weeks 1–3
Ship the highest-leverage fixes
Code, media and app changes go live in priority order. Quick wins first; structural weight next.
-
04Week 3+
Re-test & handoff
Before/after on the templates that sell. A short list of what to watch so speed doesn't quietly reverse as apps pile up again.

Speed gets people in. These keep them buying.
Start with a UX audit
If the journey is leaking after the page loads, we find where shoppers stall — and design the fixes.

Once the store is fast enough to use, CRO ships and tests the changes that move revenue.

Case studyGood questions
What merchants ask before a speed project.
No. Lighthouse is a lab snapshot. We use it, plus waterfalls, theme and app inventory, and field Core Web Vitals — then we change the code. A green score that doesn't match the live store isn't the goal.
Only the ones that don't earn their weight — or that we can replace with lighter theme code. Reviews, analytics and checkout extras stay when they're actually used. Duplicate pixels and abandoned apps go.
Yes — especially on mobile. A late first paint is a bounce you never see in the heatmap. Gooseberry cut load time in more than half and grew from a few thousand a month to $100K+. Speed isn't the only lever, but a slow store caps every other one.
No. Plus helps with some checkout and automation work, but theme weight, images and apps slow every plan. We optimize the storefront you have.
Most stores see the first shipped fixes inside two to three weeks after kickoff. Full scope depends on how stacked the theme and app list are — we'll give you an honest timeline on the intro call.
That's the point. We don't flatten the brand to chase a score. Photography, type and layout stay — we change how they load.
