What a Shopify site speed audit covers

Shero's speed audit reviews Core Web Vitals, theme code quality, image optimization, app load impact, third-party script configuration, mobile performance, and redirect efficiency. The output is a prioritized fix list with specific recommendations, implementation locations, and measurable targets for each issue found.

  • Core Web Vitals (LCP, CLS, INP)
  • Theme code and render-blocking audit
  • Image and media optimization
  • App load impact assessment
  • Third-party script audit
  • Mobile performance and checkout speed

Why Shopify brands work with Shero on speed and performance

Most Shopify speed problems are caused by a small number of issues. Knowing which ones are affecting your store requires measuring, not guessing.

01

The fix list is prioritized by revenue impact, not technical severity

Not every speed issue is worth fixing immediately. Shero ranks findings by their estimated conversion and revenue impact so your team works on the changes that move the needle first, not the ones that are easiest to fix.

02

App audit that identifies what is slowing checkout and product pages

Each Shopify app adds JavaScript to your store. Shero audits every installed app's load impact, identifies the ones adding disproportionate weight, and recommends removal, replacement, or load optimization. STX's high-traffic store required this audit before launch events.

03

Theme audit that goes beyond Google PageSpeed recommendations

Google PageSpeed Insights flags symptoms. Shero identifies causes: render-blocking CSS, unused JavaScript bundles, inefficient Liquid loops, and layout shift triggers in the theme code. These require theme-level fixes, not plugin-level patches.

04

Image and media optimization with measurable before-and-after

Unoptimized images are the most common source of LCP failures on Shopify. Shero audits image formats, dimensions, compression, and lazy loading configuration, then implements fixes with before-and-after measurements so the improvement is documented.

05

Mobile performance reviewed separately from desktop

Mobile and desktop performance problems have different causes. A store that scores well on desktop PageSpeed can still fail on mobile due to render-blocking resources, uncompressed images at mobile breakpoints, or a checkout flow that does not perform on slower connections.

06

Implementation support, not just a report

Speed audit reports that sit unimplemented do not improve performance. Shero provides implementation support for every finding, either as part of the audit engagement or as a follow-on development scope, so the fixes actually get deployed.

How Shero runs a Shopify site speed audit

01

Onboarding: Access and Baseline

We collect access to Shopify admin, Google Search Console, and analytics. We run baseline Core Web Vitals measurements on priority page types: homepage, collection, product, and checkout.

02

Foundation: Full Technical Audit

We audit theme code, app load impact, image and media configuration, third-party scripts, redirect chains, and mobile performance across the priority page set.

03

Optimization: Prioritized Fix Plan

Findings are ranked by revenue impact and implementation effort. Quick wins are separated from structural changes requiring development time. Each finding includes the specific fix and where to implement it.

04

Scale: Implementation

Shero implements the prioritized fixes, from image compression and lazy loading configuration to theme code changes and app removal or replacement. Before-and-after measurements are recorded for each fix.

05

Reporting: Results and Next Steps

We deliver a final report showing Core Web Vitals before and after, fixes implemented, and remaining recommendations. For stores with ongoing performance requirements, a monitoring cadence is agreed.

06

Ongoing: Performance Monitoring

New apps, theme updates, and catalog changes affect performance over time. Shero provides ongoing performance monitoring so regressions are caught before they affect rankings or conversion rates.
