Most Shopify store owners think "security check" means fraud protection. In reality, a proper store review goes much deeper — surfacing the silent issues affecting performance, compliance, and conversion that never get flagged until something visibly breaks.
Tracking That Looks Set Up But Isn't Working
Google Analytics 4, Meta Pixel, Google Ads conversion tags — these are often installed and assumed to be working. In reality, duplicate events, misfired purchase triggers, or GTM containers that haven't been updated after a theme change are extremely common. If your purchase event is firing twice, or your add_to_cart event isn't firing at all, your ad platform is optimising against bad data — and you won't know until you look.
Cookie Banners That Don't Actually Block Anything
This is one of the most widespread compliance issues in e-commerce. Under UK GDPR and the EU ePrivacy Directive, marketing and analytics cookies must only load after a user gives explicit consent. Many cookie banners are cosmetic — they display a notice, but tracking scripts fire immediately on page load regardless of what the user chooses. This isn't just a technicality; it's an active compliance risk.
Checkout Scripts and CSP Violations
Shopify's checkout environment is intentionally restricted, but it's still possible for scripts, custom fonts, or embedded elements to trigger Content Security Policy (CSP) errors. These fail silently — no visible error to the customer, but the script doesn't run. If any part of your checkout depends on a third-party tool that isn't properly whitelisted, it may not be functioning as expected.
Common Issues Found in a Store Review
- Broken tracking — Duplicate or misfired GA4, Meta Pixel, or Google Ads events.
- GDPR failures — Consent banners that don't actually block scripts before opt-in.
- CSP violations — Silent checkout script failures due to policy restrictions.
- Ghost scripts — Code from uninstalled apps or outdated libraries still loading.
- DNS & SSL issues — Misconfigured records, missing CAA entries, mixed content warnings.
- Legacy configurations — Deprecated checkout or account page behaviours limiting customisation.
Third-Party App Scripts Running Unchecked
Every app you install adds code to your store. Over time — especially across migrations, replatforms, or multiple developers — stores accumulate scripts from apps that are no longer installed, libraries that are out of date, or tools loading over HTTP rather than HTTPS. Browsers block mixed content silently, and outdated JavaScript libraries can carry known security vulnerabilities.
DNS, SSL, and Domain Configuration
A misconfigured DNS record, a missing CAA entry, or a domain that resolves inconsistently across regions can suppress search visibility and trigger browser trust warnings. These issues are especially common after domain transfers or when a store has been connected to multiple platforms over time.
Why These Issues Are So Easy to Miss
No alerts in your admin. Shopify doesn't surface CSP violations, duplicate pixel events, or consent failures — they happen invisibly.
They accumulate over time. Each theme update, app install, or developer handover is an opportunity for something to break silently.
The impact is diffuse. There's no single revenue drop you can point to — just a gradual erosion of data quality, compliance standing, and conversion rate.
Most audits don't go deep enough. A surface-level review won't catch CSP violations or pre-consent script firing — you need to test systematically.
