Shopify Performance Optimization

A slow Shopify store costs you in three places at once: search rankings, conversion rate, and customer trust. Shero audits and optimizes Shopify stores for Core Web Vitals, mobile performance, and checkout speed using a structured process that starts with data and ends with measurable improvements.

Of 1,000 Shopify stores pass Core Web Vitals on mobile

Our own benchmark, run across 1,000 live stores. The ones that passed were not on better themes. They were running fewer scripts.

Years keeping Benchmade fast

Performance is not a project we finished. It is a thing we have been doing on that store for three years while the catalog, the apps and the campaigns kept changing around it.

2.0-2.5s

Median mobile LCP across the stores we tested

The threshold is 2.5 seconds, so the median Shopify store is sitting right on the line. Half of them tip over it the next time someone installs an app.

3x

Faster load, Swag Golf

We rebuilt the theme around their limited-release drops and tripled load speed. Mobile conversion went up 28% in the same work.

"Working with Shero Commerce for the past three years has been a game-changer for our B2B ecommerce business. Their expertise in website support and eCommerce strategy has significantly improved our online presence and optimized our B2B operations."

Your store might be fast enough in the office

Most Shopify performance problems are invisible until you measure them on a real mobile device on a real connection. The issue is usually not your theme or your hosting. It is the combination of apps installed over time, images that were never compressed, tracking scripts that load before the page content, and a checkout flow that was set up at launch and never reviewed. Each of these alone is a minor problem. Together they cost you rankings and conversions every day.

Why brands run performance optimization with Shero

Performance optimization is not a one-time fix. Here is how Shero approaches it as an ongoing discipline rather than a single cleanup project.

01

Ongoing monitoring as the store grows

Performance degrades over time as apps are added, themes are updated, and catalog size grows. We offer ongoing performance monitoring as part of a Shopify support retainer so issues are caught before they affect rankings or conversions.

02

Mobile performance treated as the primary target

Most eCommerce traffic comes from mobile devices, but most optimization audits start from desktop scores. We optimize specifically for mobile: deferred scripts, compressed images, streamlined checkout fields, and Core Web Vitals compliance on smaller screens.

03

Images and media optimized at scale

Images account for a large share of page weight on most stores. We compress and reformat images to WebP or AVIF, resize oversized assets, and implement lazy loading so pages load fast without sacrificing visual quality.

04

Tracking cleaned up through Google Tag Manager

Google Tag Manager and third-party tracking scripts are among the most common sources of page speed problems. Shero audits every tag before the performance fix list is produced. Analytics configuration is reviewed alongside performance work because accurate data and fast pages are both required for good decisions.

05

App bloat is the first thing we fix

Most slow Shopify stores have the same problem: too many apps injecting scripts that were never removed. We audit every installed app, identify which ones are redundant or unused, and clean up the load order. This alone produces measurable speed gains on most stores.

06

Audit before we touch anything

Every performance engagement starts with a full audit of apps, theme code, media, and third-party scripts. Site speed audit is available as a standalone deliverable for brands that want a prioritised fix list before committing to an ongoing engagement.

How Shero's performance optimization engagement works

01

Measure, week one

PageSpeed Insights and GTmetrix on the priority page types, plus field data from Search Console, and a baseline on a real mobile device on a real connection. Lab scores and field scores disagree more often than people expect, and the field data is the one Google ranks on.

02

App and script inventory

Every installed app, every tag, and what each one adds in weight and blocking time. You get the list with a cost per app, which is usually the first time anyone has seen it priced.

03

The cuts

Redundant apps removed, duplicate tags consolidated through Tag Manager, load order fixed so nothing blocks the first paint. This is where most of the gain happens and it needs no design decisions.

04

Media and theme

Images to WebP or AVIF at the right dimensions, lazy loading configured properly, render-blocking CSS and unused JavaScript dealt with in the theme. Slower work, and the part that needs a staging copy.

05

Verify on the field data

Core Web Vitals before and after, from field data rather than a lab score, because a passing lab score on a failing store is the most common false result in this work.

06

Monitoring, ongoing

A new app, a theme update or a catalog change can undo a month of work in an afternoon. We watch the field data monthly and tell you when something has regressed, usually before it reaches the rankings.
