Why does Shopify store speed matter?

Speed directly affects revenue. Slower stores have higher bounce rates and lower conversion – even a one-second delay can measurably cut sales. Speed is also a Google ranking factor, so a faster store earns more organic traffic as well as converting more of it.

What are Core Web Vitals?

Core Web Vitals are Google's key performance metrics: Largest Contentful Paint (loading), Interaction to Next Paint (responsiveness) and Cumulative Layout Shift (visual stability). They affect both user experience and search rankings, and they're a core focus of our optimisation work.

How fast can you make my Shopify store?

It depends on your starting point and what's slowing the store down – heavy themes, too many apps, unoptimised images or bloated code. We routinely take stores to sub-2-second loads and 90+ Lighthouse scores, and we tell you what's realistically achievable after the audit.

Do too many apps slow down Shopify?

Often, yes. Many apps inject scripts and styles on every page, used or not. We audit your apps, remove or replace the worst offenders and clean up the code they leave behind – without changing how the store looks.

Why Teplin

Real speed gains, not a vanity score

Anyone can chase a green Lighthouse number. We optimise what your customers actually feel and what shows up in conversion and rankings.

Creating Value

01/05

Real-world speed, not just lab scores

A perfect Lighthouse score means nothing if real users on real devices still wait. We optimise for field data and actual experience, not just the test bench.

02/05

Speed tied to revenue

We don't optimise for its own sake. We focus on the speed improvements that move conversion, bounce and rankings. Those are the metrics that actually matter to your business.

03/05

We fix causes, not symptoms

As developers, we go into the code to tackle heavy themes, render-blocking scripts and bloated apps. We fix the root cause instead of papering over it with a caching app.

04/05

App & bloat clean-up

Most slow Shopify stores are weighed down by apps loading scripts on every page. We audit, trim and replace the worst offenders to lighten the load.

05/05

It stays fast

We don't just hit a number once. We set you up to keep performance high as you add content, apps and campaigns, so the speed lasts instead of being a one-off spike.

Core Web Vitals

The metrics Google and your customers care about

Core Web Vitals shape both your search rankings and how fast your store feels. These are the three we optimise hardest.

LCP

01

Largest Contentful Paint

How quickly the main content loads. We target under 2.5 seconds so visitors see your store fast, not a blank screen.

INP

02

Interaction to Next Paint

How responsive the store feels when tapped or clicked. We keep interactions snappy so nothing lags when customers engage.

CLS

03

Cumulative Layout Shift

How visually stable the page is. We stop content jumping around as it loads, so buttons don't move just as customers tap.

What's included

Everything in our speed optimisation service

A complete performance overhaul, from audit to implementation to keeping it fast over time.

Why speed pays

Every second costs you sales

Speed isn't a technical nicety. It's a revenue lever. Slower stores see higher bounce rates and lower conversion, and the effect compounds. Every visitor who leaves before the page loads is a sale you paid for and lost.

Faster stores convert better, rank higher and feel more premium. It's one of the rare improvements that lifts both the traffic you get from Google and the share of it that buys, often for far less than the equivalent in ad spend.

Build it, then grow it

Stores get slow again

New apps, new campaigns and new content all risk creeping the load time back up. The brands that stay fast treat performance as ongoing, not a one-off. Most speed clients keep us on a retainer to keep the store lean as it grows.
