The Comprehensive Shopify Technical Audit Checklist (2025 Edition)
A beautiful store that loads slowly or has broken links is like a Ferrari with a flat tire. It looks great, but it won't get you anywhere. This technical audit checklist covers the exact process I use when auditing 7 and 8-figure Shopify brands.
Phase 1: Performance & Speed (Core Web Vitals)
Google doesn't just want your site to be fast; they want it to represent a good user experience. Since March 2024, INP (Interaction to Next Paint) replaced FID, so if you haven't audited your site recently, you're likely failing.
⚡ Performance Checklist
- Run PageSpeed Insights: Aim for >70 on Mobile and >90 on Desktop.
- Check LCP (Largest Contentful Paint): Is your hero banner loading under
2.5s? Use
fetchpriority="high"on the LCP image. - Fix Layout Shifts (CLS): Ensure all images and video elements have
explicit
widthandheightattributes. - Lazy Load Images: Ensure all non-critical images have
loading="lazy". - Audit Third-Party Scripts: Remove unused apps. Move tracking pixels to Shopify Pixels (Customer Events) where possible.
Phase 2: Technical SEO Audit
It doesn't matter how good your content is if Google can't crawl it efficiently.
1. Canonical Structure
Shopify creates duplicate URLs by default (e.g.,
/collections/all/products/product-name vs /products/product-name).
Ensure your theme is editing the canonical tags correctly to point to the root product URL.
2. Structured Data (Schema Markup)
Use the Schema Validator. You should have valid JSON-LD for:
- Product (with Price, Availability, and AggregateRating)
- Organization
- BreadcrumbList
- Article (for blog posts)
3. Sitemap & Robots.txt
Verify that your sitemap.xml is submitted to Google Search Console and that your
robots.txt isn't blocking critical resources.
Phase 3: Codebase & Theme Health
Over time, Shopify themes accumulate "code rot" from installed and uninstalled apps.
🧹 Code Cleanup Checklist
- Inspect
theme.liquid: Look for script tags from deleted apps. They often leaverender 'app-snippet'lines that cause errors. - Check Assets Folder: Delete CSS and JS files that are no longer referenced.
- Console Errors: Open Chrome DevTools > Console. Are there red errors? A clean console = a happy browser.
Phase 4: App Audit (The Silent Killer)
Every app you install adds JavaScript execution time. Be ruthless.
- Redundant Apps: Do you have three different apps for popups, rewards, and reviews? Consolidate them.
- Frontend vs. Backend: Backend apps (like order management) usually don't slow down your site. Frontend apps (page builders, sliders) do.
- Theme App Extensions: Ensure apps are using modern Theme App Extensions, which are faster and cleaner than old script tag injections.
Phase 5: User Experience (UX) & Accessibility
You can be sued for having an inaccessible website. Plus, accessibility improves SEO.
- Alt Text: Do all images have descriptive alt text?
- Keyboard Navigation: Can you tab through the entire checkout process?
- Contrast Ratios: Is your grey text on a white background readable?
- Broken Links: Use a crawler to find and fix 404 errors.
