Performance and technical debt

Star service

Fix a slow, overcomplicated Shopify store. Prove the numbers are real.

Most stores we see are not slow because of the theme. They are slow because of years of apps, snippets and pixels nobody removed. The same mess breaks tracking: Shopify says one number, GA4 and Meta say another, and ad money gets spent on guesses. We clean it up, measure it with real customer data, and show you the before and after.

Is this you?

What merchants say in the first email.

  • "Our store is slow" and nobody can say which app did it
  • Field Core Web Vitals fail on mobile, where most of your orders come from
  • App bills that grew every month and nobody has audited
  • Shopify orders, GA4 and Meta disagree, so ad spend is being judged on bad data
  • Pixels firing twice, or not at all since the checkout changes of 2025 and 2026
  • A theme with five years of edits that nobody dares touch

What you get

The result, in plain terms.

Faster pages on real customers' phones, measured with field data, not a lab score
Unused paid apps removed, and Shopify Flow set up where it does the same job for free
One set of numbers you can trust: Shopify, GA4 and Meta reconciled with a live test order
Consent handled properly for EU and UK traffic so remarketing keeps working
A ranked backlog of what to fix next, with the before-number recorded so the after is provable

How we do it

The way we work on this.

01

Field data first

We start from what real customers experience: Chrome's field data for your domain, on the devices and networks they use. A Lighthouse score in a lab tells you almost nothing, so we never sell one.

02

Apps before theme code

Most speed is lost to third-party scripts, not Liquid. We list every app and pixel, what it costs, what it loads, and whether anything still uses it. Removals come before rewrites.

03

A live test order, every time

We place a real order and follow the event through Shopify, GA4 and Meta. Double-counting, missing purchases and paused pixels all show up in that one order. A dashboard light stays green through every one of them.

04

Shopify-side only, on purpose

We fix the plumbing that Shopify controls: Web Pixels, server-side events, consent, app conflicts. Attribution models and campaign management belong to your marketing team or agency, and we work alongside them.

05

Before and after, written down

Every fix ships with the number it changed. Product page load time, purchases matched between systems, dollars a month saved on apps. If a number did not move, we say so.

After it ships

Launch is the midpoint.

Performance degrades every time an app is added or a theme is updated. That is why this service bridges into a monthly plan: a speed check, an app-bill review and a tracking check with a live test order, every month, with one ranked improvement shipped from your backlog.

Monthly plans from $800

Deliberately not included

  • Ad account management or attribution modelling (we refer you to a partner and share what we found)
  • Merchant Center or Meta catalog recovery beyond the Shopify-side feed
  • Claiming or owning any client ad account. We request access; you keep admin.

FAQ

About this work.

The questions merchants ask before saying yes. Straight answers, including the ones that lose us work.

No, and be careful with anyone who does. Scores can be faked by hiding scripts from the test. We commit to measured improvements in field data and to a written before and after on every fix.
