Store audit
Why every store needs an eCommerce technical audit
What a technical audit checks across performance, security, code, UX and SEO, the problems it usually finds and what fixing them returns.
On this page
Your store is running and customers are buying. But how do you know it isn’t leaking revenue through hidden performance issues, security gaps or conversion blockers?
Most store owners can’t tell. They manage what they can see: sales, customer feedback and traffic. The technical health of the store stays invisible unless someone looks, and a technical audit brings it into focus.
What is a technical audit?
An eCommerce technical audit is a systematic review of your store’s performance, security, code quality, user experience and SEO. It shows what’s working, what’s broken and what’s costing you money.
It works like a checkup: tests, not guesses, on the parts of your store you cannot see.
What does a store audit cover?
Performance and speed
The audit measures:
- Page load time (desktop and mobile)
- Core Web Vitals (LCP, INP, CLS)
- Time to first byte (TTFB)
- Image optimization opportunities
- CSS and JavaScript bundle sizes
- Caching strategy effectiveness
- Database query performance
- Server response times
Why it matters: slow pages cost sales. When speed is the main problem, Magento performance optimization picks up where the audit ends.
Security vulnerabilities
The audit checks:
- Outdated software and unpatched vulnerabilities
- Weak SSL/TLS configuration
- Password policy and account security
- PCI DSS compliance status
- Payment gateway integration security
- SQL injection and XSS risks
- Data encryption in transit and at rest
- User access controls and permissions
Why it matters: a breach costs far more to clean up than an audit costs to prevent it.
Code quality
The audit evaluates:
- Extension conflicts and deprecated code
- Custom code against best practices
- Database schema and query optimization
- Magento core modifications (which should be avoided)
- Test coverage and automation
- Code maintainability and documentation
Why it matters: technical debt costs more the longer it waits.
User experience (UX)
The audit reviews:
- Checkout flow usability
- Mobile responsiveness
- Navigation clarity
- Conversion funnel bottlenecks
- Accessibility compliance (WCAG)
- Form optimization and error handling
- Search functionality and filters
Why it matters: a confusing checkout is one of the most common reasons shoppers abandon a full cart, so UX fixes often pay back first.
SEO
The audit checks:
- On-page SEO (titles, descriptions, headings)
- Structured data and schema.org markup
- Sitemap and robots.txt
- Mobile-first indexing readiness
- Core Web Vitals impact on rankings
- Duplicate content issues
- Backlink profile quality
- Organic traffic trends and opportunities
Why it matters: organic search is a major traffic source for most stores, and SEO fixes compound over time.
Real issues found in audits
These are problems we find often:
- Outdated Magento versions: exposed to known vulnerabilities. A simple version upgrade is often available.
- Broken product images: missing files and bad redirects. Fixing them restores product pages.
- Slow database queries: single queries taking seconds. Indexing fixes cut them sharply.
- No caching configured: every page loads from the database. Varnish and Redis cut TTFB on cached pages.
- Confusing checkout flow: more steps than needed. Fewer steps cut abandonment.
- Conflicting extensions: 3 to 5 extensions fighting over JavaScript and breaking functionality. A code review finds them.
- Unnecessary custom code: thousands of lines of custom code for features available as standard extensions, which is pure technical debt.
- No monitoring in place: no visibility into performance or errors. An APM setup gives real-time insight.
eCommerce audit ROI
| Issue type | What the fix changes | When it shows |
|---|---|---|
| Page speed | Faster pages keep more shoppers on the path to checkout | As soon as the fix is live |
| Checkout optimization | Fewer abandoned carts at the payment and shipping steps | Within the first weeks of traffic |
| Security fixes | Lower risk of a breach, downtime and lost customer trust | Immediately |
| SEO optimization | Pages that search engines can crawl, index and rank | Over the following months |
| Code cleanup | Less development time per change and fewer regressions | On every release after the cleanup |
The return depends on your traffic, catalog and how many issues the audit finds, so we size it for your store in the audit report rather than quote a generic figure.
What our audit checks
Our free Magento store audit is a performance audit. It needs no login, because we measure everything from outside your store:
- Core Web Vitals performance
- Page load time on mobile and desktop
- Time to first byte and server response
- Caching (full-page and browser cache), read from response headers
- CDN configuration and asset delivery
- Image optimization and lazy loading
- JavaScript and CSS bundling
- Third-party script impact
A code and security review goes deeper. It needs read access to your Git repository or server access over SSH, so we scope it with you on a call. It can cover:
- Magento version and extension compatibility
- Extension conflicts and performance drains
- Custom code quality and maintainability
- Database optimization and indexing
- SSL/TLS and PCI DSS compliance
- Customer data protection measures
- Payment gateway integration security
- API rate limiting and abuse prevention
- Error logging and monitoring setup
- Backup and disaster recovery readiness
You get a detailed report with findings prioritized by business impact, specific recommendations and an effort estimate for each fix.
When should you get an audit?
- Annual baseline: every established store should be audited yearly to stay aligned with best practice
- Before scaling: ahead of major marketing campaigns or seasonal peaks
- After incidents: after downtime, security issues or performance problems
- After updates: after Magento, extension or infrastructure changes
- New ownership: when you take over the management of an existing store
- Growth milestones: when orders or traffic cross new thresholds (100K, 500K, 1M+ orders a year)
Getting started
A technical audit is one of the most useful first steps for a store that feels slow, fragile or hard to change: it turns guesswork into a ranked list of fixes.
Our free audit is a good starting point: you see how fast your store is and get a clear list of fixes. For code and security, we scope a deeper review on a call. To turn the findings into a longer-term plan, our eCommerce consultancy team builds the roadmap with you.
