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.

Years optimizing eCommerce store performance

Shero has been auditing and optimizing eCommerce store performance since 2010, working across Shopify, Shopify Plus, Magento, and BigCommerce stores of varying complexity and traffic volume.

70%

Of consumers say speed affects their decision to buy

70% of consumers report that page speed affects their willingness to buy from an online store according to Shopify data. Slow load times on mobile are the leading cause of cart abandonment before checkout.

CWV

Google's performance standard for ranking and UX

Core Web Vitals are Google's primary page experience signals and directly affect organic search rankings. Shopify SEO and performance optimisation are coordinated in every engagement where both are in scope.

27%

Potential conversion rate improvement from speed

A one-second improvement in mobile page speed can increase conversion rates by up to 27% according to Shopify research. Site speed is one of the highest-leverage optimizations available to eCommerce stores.

"Our journey from Magento to Shopify was riddled with complexities and challenges. Shero Commerce was our beacon. Now our platform costs are reduced and the headaches are gone."

Patrick Rice, CEO, Painful Pleasures

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

Audit before we touch anything

Every performance engagement starts with a full audit: PageSpeed Insights, GTmetrix, Core Web Vitals, app inventory, image analysis, tracking script review, and mobile checkout testing. You see the full picture and the priority order before any code changes.

02

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.

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

Unmanaged tracking scripts from Google Analytics, Meta Pixel, Klaviyo, and other tools slow down every page load. We consolidate tracking through Google Tag Manager, remove duplicate tags, and ensure scripts load without blocking page content.

05

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.

06

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.
