Theme Rebuild Required
01The Problem
Every app you install adds its own scripts to every page. One or two apps rarely matter, but a year of installs quietly turns into a slow store nobody meant to build.
The problem
You've installed apps over time to add features, reviews, upsells, personalization, and each one added its own scripts to every page. Now your store feels sluggish, PageSpeed scores are low, and you're not sure which apps are actually the problem versus which ones you need.
How we solve it
We audit every installed app, your theme code, and your images to find what's actually slowing pages down, then fix it directly, compressing images, deferring scripts, cleaning up code, without a theme rebuild or a redesign you didn't ask for.
No theme rebuild required
We optimize your current theme and design rather than starting over.
Every app reviewed
Real impact measured per app, not a generic 'remove some apps' suggestion.
Measured before and after
PageSpeed and Core Web Vitals scores documented so improvement is verified.
02Our Speed Optimization Process

Before & after report
PageSpeed and Core Web Vitals scores measured before and after so gains are verified.
04Compare Options
A speed app can automate a few fixes, and a generalist can remove an app or two. Here is where each one runs out and where a dedicated audit pays off.

Feedback from ecommerce teams we have built stores, checkouts, and integrations for.

What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.
Sarah Mitchell
Operations Manager of Harborline Commerce
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
James Whitmore
Head of Marketing of Lumen Outdoor
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

08Overview
DeveloperLook audits your Shopify app stack, theme code, and images to find what's actually slowing your store down, then fixes it without a full theme rebuild. Projects start from $399, most go live in 3 to 7 business days, and we measure speed and Core Web Vitals before and after so improvement is verified, not assumed.
Who it's for
Stores with a slow PageSpeed or Core Web Vitals score
Google PageSpeed Insights or Search Console shows your store failing Core Web Vitals, and you're not sure why.
Stores with a growing app stack
You've installed several apps over time, and pages feel noticeably slower than they used to.
Stores that don't want to lose their current design
You like your theme and don't want a rebuild, you just want it faster.
Stores worried speed is costing conversions
You suspect slow load times are increasing bounce and cart abandonment, but haven't confirmed it.
Stores that tried speed apps with little result
You installed a speed optimization app, but PageSpeed scores barely moved.
Not a fit for
You're not on Shopify. A general website speed optimization service, not this Shopify-specific one, would fit your platform instead.
You want a deep technical SEO and Core Web Vitals diagnostic as its own project, separate from general speed fixes. A dedicated Core Web Vitals optimization service covers that angle specifically.
You want a full custom theme rebuild, not an optimization of your current one. Our Custom Shopify Theme Development service covers that.
You want a broader audit covering UX, conversion, and technical debt beyond speed. Our Shopify Store Audit service covers that wider scope.

12FAQ
Straight answers on Shopify speed, app bloat, and Core Web Vitals for merchants.
Start with an audit of your installed apps, theme code, and images to find what's actually slowing pages down, then fix the highest-impact issues first, usually bloated apps, unoptimized images, and render-blocking scripts.
We measure your current PageSpeed and Core Web Vitals scores, identify which apps and theme elements are adding the most load time, and fix those directly rather than guessing at generic best practices.
Our projects start from $399 for a full audit, with implementation typically running $999 to $2,199 depending on your app count and theme complexity. You get a fixed quote after a free review of your store.
A straightforward audit and optimization project typically takes 3 to 7 business days. Larger app stacks or heavily customized themes needing a deeper refactor can take 1 to 2 weeks.
Yes, most apps add their own JavaScript and CSS to your pages, and the impact adds up as you install more of them. Not every app is equally costly though, which is why an audit of actual impact matters more than just counting how many you have installed.
Google considers a page 'good' when it passes Core Web Vitals: Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1. A PageSpeed Insights score of 90 or above generally reflects that.
Often, yes. Many gains come from optimizing how existing apps and scripts load, deferring non-critical ones, compressing images, and cleaning up theme code, rather than removing functionality you actually use.
No, not unless you ask for design changes. We optimize the code and assets behind your current design rather than rebuilding or restyling it.
We record your PageSpeed Insights and Core Web Vitals scores before starting, then re-test the same pages after optimization using the same tools, so you see a documented before-and-after comparison rather than a vague promise of 'faster'.
