Liquid theme code & frontend architecture
I inspect theme structure, render-blocking assets, expensive Liquid loops, JavaScript/CSS payloads and orphaned code snippets left behind by old apps.

Shopify technical audit: find out what is slowing down or blocking your store
After two or three years of theme edits, agency handovers and apps being installed and removed, many Shopify stores become slow, fragile and expensive to change. Every new feature risks breaking something else, and poor mobile speed hurts conversion rates. With an independent technical audit, I review your code, apps, performance, technical SEO and data flows to give you a prioritised action plan.
Why automated PageSpeed reports are not enough
A PageSpeed Insights score tells you a page is slow, but it does not tell you whether the bottleneck comes from a nested Liquid loop on collection pages, leftover JavaScript from an app uninstalled six months ago, unoptimised media or an overloaded GTM container. A technical audit inspects the actual theme code, store configuration and network waterfall to separate high-impact fixes from wasted effort.
When to request a Shopify technical audit
- Pages load slowly on mobile or take too long to respond when a customer interacts with them
- Dozens of apps have accumulated over time: monthly software costs are climbing and cart or checkout conflicts keep appearing
- Organic traffic has plateaued or dropped due to indexation issues, duplicate collection filter URLs, broken canonicals, structured data errors or hreflang mismatches
- You are changing agencies or planning a redesign and want an honest answer on whether to refactor the current theme or rebuild on a clean Online Store 2.0 foundation
What I review during the audit
Installed app stack, checkout & tracking
I map every installed app, measure its storefront impact and verify checkout setup alongside Google Tag Manager, GA4, Consent Mode and ad pixels.
Technical SEO & catalogue structure
I review URL hierarchy, collection tag and filter handling, canonical tags, sitemaps, robots rules, Schema.org structured data (Product, Offer, Breadcrumb, FAQ) and Shopify Markets hreflang.
Integration & operational reliability
If the store connects to an ERP, CRM or 3PL warehouse, I check where inventory drift, silent webhook failures or manual bottlenecks occur.
What you receive at the end of the audit
- A clear, actionable technical report written for both leadership and developers—no generic copy-pasted automated exports
- A prioritised backlog of issues ranked by business impact (conversion, SEO, stability) and implementation effort
- An audit of your installed apps showing what to keep, replace with native features or remove
- Specific code-level recommendations (files, Liquid sections, scripts) to improve Core Web Vitals and loading speed
- A technical SEO fix checklist covering canonicals, structured data, hreflang, redirects and collection filters
- A walkthrough call with your team to agree on immediate fixes—whether implemented by me or your in-house developers
Frequently asked questions about Shopify technical audits
Can you also implement the fixes after the audit?
Yes. The audit is designed to give you an objective, vendor-neutral assessment first. Once we review the prioritised roadmap together, you can either have me implement the fixes (in full or for the most critical parts) or hand the specifications to your internal team.
What access do you need to run the audit?
We agree which Collaborator permissions I need based on the audit scope, for example to inspect the theme, apps or settings. Where useful, I request read access to Google Search Console and GA4. I make no changes to your live store during the audit.
Is it better to optimise our current theme or rebuild from scratch?
Answering that question honestly is one of the main goals of the audit. Very often, surgically removing leftover app scripts, consolidating 4–5 redundant apps and refactoring a few heavy Liquid sections restores speed and stability at a fraction of the cost of a full rebuild.
How long does a Shopify technical audit take?
Typically between one and two working weeks from receiving access, including code inspection, data review and the final walkthrough call with your team.
