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.

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.

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.

The Complete Technical Audit Checklist

Here's the exact audit process I follow, organized by priority. I typically complete a full audit in 2-3 days for most stores.

Priority 1: Performance (Day 1)

• Run Google Lighthouse on homepage, product page, collection page (both mobile and desktop)
• Check Total Blocking Time (TBT) — should be under 200ms
• Check Largest Contentful Paint (LCP) — should be under 2.5s
• Audit JavaScript payload size — identify apps contributing most to bloat
• Check image optimization: WebP format, lazy loading, proper srcset attributes
• Review third-party script loading (Google Analytics, Meta Pixel, Klaviyo, etc.)
• Test on actual devices, not just simulators (Samsung, iPhone, slow Android)

Priority 2: SEO Health (Day 1-2)

• Verify canonical tags on all page types
• Check for duplicate content (especially filtered collection URLs)
• Audit meta titles and descriptions for uniqueness and keyword targeting
• Verify structured data (Product, BreadcrumbList, Organization schemas)
• Check robots.txt and sitemap.xml for errors
• Review internal linking architecture
• Identify and fix broken links (404s)

Priority 3: Conversion & UX (Day 2)

• Mobile responsiveness on 3+ device sizes
• Add to Cart functionality testing across all product types
• Checkout flow testing (including edge cases: out of stock, high quantity, discount codes)
• Cross-browser testing (Chrome, Safari, Firefox, Samsung Internet)
• Accessibility basics: color contrast, alt text, keyboard navigation

Priority 4: App Stack Review (Day 2-3)

• List all installed apps and their monthly cost
• Identify ghost code from uninstalled apps
• Flag redundant apps (e.g., two review apps, two upsell apps)
• Test for app conflicts using the isolation method from my App Conflicts Guide
• Calculate total monthly app spend and recommend native alternatives

Tools I Use for Audits

Frequently Asked Questions

How often should I audit my Shopify store?

I recommend a full technical audit every 6 months, or immediately after any major change (theme update, new app installation, migration). Quick performance checks (PageSpeed test) should be done monthly.

How much does a professional Shopify audit cost?

Prices vary widely. Basic audits run $300-$500, while comprehensive audits with actionable recommendations and implementation support range from $1,000-$3,000. The ROI is usually immediate because fixing performance issues alone can boost revenue by 10-20%.

Can I do a technical audit myself?

You can run the tools yourself, but interpreting results and knowing what to fix requires experience. For example, PageSpeed might flag "Reduce unused JavaScript" but knowing which app is responsible and whether it's safe to defer requires understanding of Shopify's architecture.

What's the #1 issue you find in audits?

App bloat. Nearly every store I audit has 3-5 apps that are either unused, redundant, or could be replaced with 10 lines of custom code. This alone typically improves PageSpeed scores by 15-30 points.
