Shopify speed and ad tracking fixes: for stores where the ads bring visitors but not sales I help Shopify stores sell more to the visitors you already pay to bring in. I find the spots where shoppers give up, and then I fix them. One example. A clothing brand's product pages took 15.4 seconds to load. Five weeks before Black Friday, I got them to 7.4 seconds. That is the job: I find what slows your store down, and I fix it. The same work keeps finding a second problem: numbers you cannot trust. The code that tells Meta or Google about a sale fires twice, so sales count double. Ads run across every product, with no check on which ones earn. Apps bill every month for work nobody has measured. So I also check what your money is really doing, instead of trusting what Google, Meta and the apps say. Then I fix what I find. I work with established stores run by their founders. To me, speed and ad spend are sales problems, not technical boxes to tick. What I work on, eight ways in: Speed check. I measure how fast your pages load for real shoppers on a phone. I find what makes them wait, and I fix it. Accessibility check. I test your store the way a keyboard user or a screen reader meets it. I check whether a widget sits on top of problems it does not fix. You get the findings in the order a complaint would reach them. Shopify deadline check. Shopify changes its rules on set dates. Scripts ended on 30 June. Order status script tags ended on 26 August. I find what has already stopped working on your store and what is dated ahead, and I make the repairs. Tracking and attribution fix. Meta Pixel, GA4 (Google Analytics) and server-side tracking. I remove the double counting and prove it in your own dashboards. Ad spend by product and the app bill get read in the same pass. Google and Meta recovery. Your products stopped showing on Google or Meta. I find where the connection broke and get them showing again. Sale price check. AI shopping tools, like ChatGPT, now get your "was" prices from Shopify. I check that yours reach them right. Builds and theme upgrades. New sections and modern themes, with your custom work and your tracking still running. Every change to the live site has a way back. Partner Seat. 25 hours a month. I watch speed, the pages customers see, broken links, tracking and app bills. Your work goes first in the queue. Each check is $285. If you go ahead, I take the fee off the fix price. Key results: Product page load time cut from 15.4 seconds to 7.4 seconds, 52% faster. Mobile PageSpeed on product pages from 18 to 28. The apps the client chose stayed in place, at their call. Two apps were billing to track what the store's own Google channel already did. I removed them, checked the tracking was clean, and took $199 a year off the app bill. Repeat clients going back to 2018. One store has come back for 14 projects over four years. How I work: A paid check first. It measures the real problem, no guessing. If you go ahead, I take the fee off the fix price. Work in stages. You approve each one. Every delivery ends with before and after numbers, and a short list of the next things I found. 80+ projects done. Clients in the US, Canada, UK, Australia and Denmark. Send me your store address. I will tell you what slows it down, whether your numbers add up, and what a complaint would find first. No commitment.
Shopify Code Audits for Themes, Apps and Integrations
A store that has been live for a few years carries code nobody remembers adding: snippets from apps you uninstalled, edits inside the theme's own files, a tag from a campaign that ended two summers ago. A Shopify code audit is a developer reading through all of it and reporting what's safe, what's risky and what to fix first, with an effort estimate for each item.
It is not a commercial store audit. Conversion, merchandising and UX reviews belong to Store audits; a technical audit covers the theme, apps, integrations, access, checkout and tracking underneath. Speed-only projects and accessibility audits are separate services as well.

How to choose a developer for a technical audit
An audit is only as useful as the plan it leaves behind. The report should be something another developer could pick up and work through without phoning the auditor.
Ask for a sample report before anything else. An anonymised report from a recent audit shows the depth you'll get. Each finding should name the file, app or setting involved, explain why it matters and rate its severity. A branded export of a free speed test doesn't count.
Insist on a remediation plan with hours. Every finding needs an effort estimate and an owner: a change your team can make in the admin, a developer task, or a decision only you can take. Findings should be sorted into fix now, fix with the next theme update, and leave alone. That last group matters, because not every old snippet is worth paying to remove.
Keep the audit separate from the fix. Buy the audit at a fixed fee and treat remediation as a separate quote. Ask the auditor whether they're comfortable with another developer doing the work. If the report reads like a pitch for a rebuild, get a second opinion before you commit.
Match the auditor to your stack. A single-theme store with a dozen apps needs a strong theme developer. A Plus store with expansion stores, B2B, Functions and an ERP feed needs someone who has worked across all of those, and their sample report should show it.
Tell them what changed and when. The auditor works faster with a timeline: theme installs and updates, apps added and removed, agencies that have had access, integrations switched on. An afternoon spent on that list saves paid hours of detective work.
Red flags. A report produced entirely by automated scanners. A headless rebuild recommended before anyone has opened the code. No questions about integrations or who else works on the store. A request for your store owner password.
What a technical audit should check after 2026's platform changes
Several recent Shopify changes left code behind that still looks fine in the admin. An audit done today should check these by name.
Discount and shipping logic that relied on Scripts. Shopify stopped letting merchants edit or publish Scripts on 15 April 2026 and switched them off completely on 30 June 2026. On a Plus store, confirm that every tiered discount, shipping rule and payment filter Scripts used to handle now runs on Shopify Functions, and that promotional copy in the theme still matches what checkout does. Custom apps containing Functions need Shopify Plus; public apps with Functions work on any plan.
Tracking from the old checkout. Plus stores had until August 2025 to move checkout.liquid and Additional Scripts customisations off their post-purchase pages (Thank you and Order status). On other plans, those two pages stopped supporting Additional Scripts and script tags in August 2026, so purchase tracking and post-purchase snippets that lived there may have gone quiet. Checkout UI extensions on those two pages work on every plan.
Edits inside core theme files. Custom code written into the theme's own files turns every update into a manual merge, so stores stop updating. The audit should list each edit and say whether it can move into its own section or snippet.
Leftover app code and heavy tags. Uninstalling an app doesn't always remove the code it wrote into the theme. Third-party tags that load on every page should be listed with their cost in LCP, INP and CLS, the three Core Web Vitals.
Access and error handling. Flag accounts for former staff and past agencies, and apps holding order or customer permissions they no longer need. For each ERP, 3PL or marketing sync, ask what happens when a call fails: does anyone find out, or do orders quietly stop moving?
How much do Shopify technical audit services cost?
Audits are usually quoted as a fixed fee once the auditor has seen the size of the store and its stack. Typical ranges:
Technical audit
$1,500 – $10,000
Theme, apps, performance, integrations
Plus architecture audit
$5,000 – $20,000
Multi-store, B2B, checkout, systems
Developer rate
$100 – $220
Per hour, senior Shopify developers
Scope moves the price more than revenue does. Each extra theme, expansion store and integration adds hours, and so does custom checkout logic. A store with thirty apps and a theme that hasn't been updated in years takes longer to read than a newer one with ten, whatever it turns over.
Budget for the fixes separately. The effort estimates in the report become your remediation budget, and remediation can cost more than the audit. Even so, a single well-scoped audit is usually cheaper than paying developers to discover the same problems one bug at a time. Send your theme name, app list and integrations to get a quote.
What does a technical store audit cover?
Most audits report on six areas, ending in a ranked plan:
Shopify theme code review
Core-file edits, unused sections, duplicate snippets and Liquid errors
Installed app code review
Installed apps, overlaps, permissions and code left by removed apps
Checkout, discounts and tracking
Scripts replacements, Functions, extensions and purchase events
Integrations and data flows
ERP, 3PL and marketing syncs, webhooks and failure alerts
Access and permissions
Staff, collaborator and app access checked against current need
Remediation plan
Findings ranked by risk, each with an effort estimate in hours
Frequently asked questions about code and theme audits
A theme-only audit suits a store with a modest app list and no integrations, or one about to hand its theme to a new developer. Once orders flow into an ERP or 3PL, or the store runs custom checkout logic, many of the risks sit outside the theme, and a theme audit will miss them. If you're unsure, book a short scoping call and let the auditor tell you what they would need to look at.
Everything a single-store audit covers, plus how the pieces fit together: which store or system is the source of truth for products, prices and stock, how expansion stores are kept in sync, how B2B and checkout extensions are set up, and which custom apps call the API and how. Expect a diagram of the systems and data flows in the report, because most Plus problems live between systems rather than inside one.
Before a redesign, a replatform or a new agency takes over, so everyone starts from the same facts. After a year or two of apps coming and going. Before peak season, when a failure costs the most. And soon, if your store used Scripts or old checkout customisations and nobody has checked what replaced them.
Usually not as part of the audit fee. The audit is diagnostic: it tells you what is wrong, how serious it is and what fixing it will take. A few urgent items, such as removing access for a former agency, can be handled the same day with your approval. Everything else goes into a remediation quote, which you are free to give to a different developer.
Yes, if access goes through a collaborator request rather than a shared login. The developer requests access, you approve only the permissions the audit needs, and you remove it once the report arrives. If they need to test anything, ask them to work on a duplicate of the live theme and not to install apps without checking with you first.
Some of it. From the admin you can compare installed apps with the ones you actually use, review staff and collaborator accounts, and see whether your theme is behind its latest version. Our technical audit guide walks through that self-check. Code-level findings, integrations and checkout logic still need a developer.
