The 25-Point Technical Audit We Run on Every Shopify Store

Before we write a single line of code for any client, The Scale Room conducts a comprehensive 25-point technical audit. This audit identifies performance bottlenecks, SEO gaps, security vulnerabilities, and conversion friction points that are silently eroding revenue.

We are publishing our complete Shopify code audit checklist so you can assess your own store. Each item includes what we check, why it matters, and what a passing score looks like.

Implementation Paths

1) Performance (8 Checkpoints)

Performance is the foundation. Slow stores lose customers before they even see a product.

Performance Checkpoints

Each checkpoint is scored as pass, warning, or fail.

LCP under 2.5 seconds on mobile (measured via PageSpeed Insights field data).
CLS under 0.1 (all images have explicit dimensions, no late-injected content above the fold).
INP under 200ms (no long tasks blocking the main thread during user interactions).
Total JavaScript payload under 300KB gzipped across all first-party and third-party scripts.
Total CSS payload under 100KB gzipped with critical CSS inlined.
Image optimization: all images served via Shopify CDN with responsive srcset and next-gen formats.
Third-party script audit: every app script categorized as essential, deferrable, or removable.
Font loading: custom fonts preloaded with font-display: swap to prevent FOIT.

2) SEO (6 Checkpoints)

Technical SEO ensures Google can crawl, index, and rank your pages correctly.

SEO Checkpoints

These checkpoints verify your store's technical SEO foundation.

Unique meta titles and descriptions on all product, collection, and page templates.
Proper heading hierarchy: single H1 per page, logical H2/H3 nesting.
Canonical tags correctly implemented to prevent duplicate content issues.
XML sitemap generated and submitted to Google Search Console with all indexable URLs.
Structured data (JSON-LD) for Product, BreadcrumbList, and Organization schemas validated without errors.
No 404 errors on critical pages. All broken internal links identified and fixed.

3) Security (4 Checkpoints)

Security auditing ensures customer data protection and regulatory compliance.

Security Checkpoints

These checks protect your customers and your business.

SSL certificate active and enforced across all pages (no mixed content warnings).
Content Security Policy headers configured to prevent XSS attacks from injected scripts.
Customer Privacy API correctly integrated with cookie consent for GDPR/CCPA compliance.
Admin account security: two-factor authentication enabled on all staff accounts.

4) Conversion Optimization (7 Checkpoints)

Conversion checkpoints ensure your store is engineered to maximize revenue per visitor.

Conversion Checkpoints

These items directly impact your bottom line.

Mobile Add to Cart button placement within the thumb zone with sticky positioning.
Cart drawer or slide-out cart with cross-sell recommendations and free shipping threshold indicator.
Trust signals (security badges, return policy, review scores) visible on product pages without scrolling.
Express checkout options (Apple Pay, Google Pay, Shop Pay) prominently displayed.
Product page load time under 3 seconds on mobile with all images and reviews rendered.
Checkout conversion rate benchmarked against industry average (typically 1.5% to 3% for DTC).
404 and error page recovery: custom 404 page with search, popular products, and navigation.

Actionable Insights

Run your store through Google PageSpeed Insights (mobile) and target a score of 70+ minimum, 90+ ideal.
Validate your structured data using Google's Rich Results Test to ensure Product schema is error-free.
Audit every installed app and remove any that are no longer actively used to reduce JavaScript bloat.
Verify that your Customer Privacy API implementation correctly gates analytics and marketing pixels behind consent.
Check that express checkout options (Shop Pay, Apple Pay, Google Pay) are enabled and prominently displayed.
