Find the real bottleneck first
Store speed isn't one number — a store can feel slow for very different reasons, and guessing wastes money. We start by measuring: what's actually blocking the page from rendering, which requests are heaviest, and where the time goes on real devices and real connections.
Only after we see the waterfall do we fix, so the work targets what's actually hurting you instead of chasing a vanity score.
- Real measurement with Core Web Vitals (LCP, CLS, INP), not just a single grade
- Audit of installed apps and the scripts each one injects on every page
- Image and font weight analysis — usually the biggest, easiest wins
- Theme code review for render-blocking JavaScript and CSS
- Testing on mobile and throttled connections, where most shoppers actually are
Fix the causes that actually move the needle
On Shopify, speed problems cluster in a few places: too many apps loading globally, unoptimized images, and a theme that ships more code than the page needs. The fixes are concrete and mostly one-time.
We cut the weight and defer what isn't needed for the first paint, so pages become interactive faster — especially on phones.
- Remove or replace apps that inject heavy scripts store-wide
- Compress, resize, and lazy-load images; serve modern formats
- Defer and minimize non-critical JavaScript and third-party scripts
- Reduce layout shift (reserve space for images/embeds) to stabilize the page
- Preload critical fonts/assets and trim unused theme code

Frequently asked questions
Why does store speed matter beyond just feeling slow?
Two reasons. Shoppers abandon slow pages, especially on mobile, so speed directly affects conversions. And Google uses page-experience signals like Core Web Vitals as a factor in rankings, so a slow store can quietly cost you search traffic too. We won't promise a specific revenue lift, but these are the mechanisms a slow store bleeds through.
Can you fix speed without removing the apps I rely on?
Often, partly. Some apps are worth their weight and we optimize how they load rather than remove them. Others inject heavy scripts on every page for a feature you use on one page — those we can scope, defer, or replace with a lighter option. We'll show you which apps cost you what, and let you decide the trade-offs.
Is it the theme, the apps, or Shopify itself?
Rarely Shopify itself — its infrastructure is fast. In practice the slowness is almost always the theme's code, oversized images, or the stack of apps loading on every page. That's good news, because those are all fixable without leaving Shopify. The audit tells us the exact split for your store before we touch anything.
