Engineering-Led Analysis

Find the Technical Friction Bleeding Your ROAS.

We don't run automated marketing scans. Our engineers manually inspect your store's architecture to calculate exactly how much revenue you are losing to ghost scripts, slow LCP, and checkout layout shifts.

How We Audit Your Store

You can request your initial audit with or without providing Shopify staff access. Here is exactly what we analyze in both scenarios.

External Scan (Without Access)

Perfect for a first look. We use Chrome DevTools and performance profiling to map your front-end rendering bottlenecks.

  • Network Waterfall: Identifying 3rd-party scripts blocking the main thread.
  • Core Web Vitals: Precise measurement of LCP, FID, and CLS scores.
  • DOM Mutation Tracking: Spotting layout shifts during the Add-to-Cart sequence.
  • Payload Size: Calculating total unused JavaScript bloat.
Recommended

Deep Infrastructure Scan (Read-Only)

We require a restricted, read-only staff account. This allows us to trace the external bottlenecks down to the exact lines of source code causing them.

  • Liquid Refactor Map: Identifying nested loops and fragile theme logic.
  • Ghost App Discovery: Finding active code from apps you deleted months ago.
  • Checkout Architecture: Analyzing `checkout.liquid` and active checkout extensions.
  • App Conflict Mapping: Finding overlapping plugins fighting for resources.
Common Questions

Shopify Conversion Rate
Optimization: Answered.

What is Shopify conversion rate optimization?+
Shopify conversion rate optimization (CRO) is the process of increasing the percentage of store visitors who complete a purchase — without increasing ad spend. At Webulux, we focus exclusively on technical CRO: eliminating ghost app scripts, fixing Core Web Vitals, and engineering checkout friction out of your funnel. Unlike surface-level tactics (pop-ups, button colors), technical fixes address the root infrastructure cause of low conversion rates.
Why is my Shopify conversion rate so low?+
A low Shopify conversion rate is most commonly caused by invisible technical problems: dead JavaScript left behind by uninstalled apps slowing your mobile load time, layout shifts during checkout causing drop-off, or LCP scores over 3 seconds bleeding ROAS before customers see your product. These issues require code-level inspection — they won't show up in GA4 or a standard heatmap audit.
What's a good Shopify conversion rate?+
The average Shopify conversion rate across all stores is 1.4 - 1.8%. High-performing Shopify Plus stores with optimized technical infrastructure typically achieve 3.5–5.5% CVR. If your store is below 2% and you're spending $30k+/month on acquisition, technical friction is almost certainly the culprit. Our clients average a +22% CVR lift after optimization — measured over 60 days.
How do I increase my Shopify conversion rate?+
To improve your Shopify conversion rate, start with a technical audit before any creative or UX work. The highest-ROI interventions are: (1) removing ghost app scripts that bloat your JS payload, (2) achieving LCP under 1.5s on mobile, (3) eliminating layout shift events in your checkout flow. These three fixes alone typically recover 15–25% of revenue currently leaking from technical friction.
How long does it take to see Shopify CRO results?+
Most Webulux clients see measurable CVR improvement within 21 days. Technical fixes — ghost script removal, LCP optimization, checkout refactoring — deliver immediate impact because they address root causes, not surface symptoms. We track results for 30 days post-launch to confirm lift holds under normal traffic conditions.
What does a Shopify CRO agency actually do?+
A technical Shopify CRO agency like Webulux audits your store's code architecture, identifies the specific technical problems reducing your conversion rate, and engineers the fixes — directly in your Liquid templates, app stack, and checkout configuration. This is different from a UX or design agency: we don't redesign your store. We fix what's technically broken in your existing infrastructure.
Will this break my store during Black Friday?+
Absolutely not. We never deploy directly to your live production theme. All technical CRO work — including Liquid refactoring and ghost script removal — is performed and rigorously QA-tested on an isolated duplicate staging theme. Once validated, we schedule a seamless deployment with zero downtime. If you have upcoming code freezes for Q4 or BFCM, we align our deployment schedules to guarantee stability.
Do you work with our existing dev team?+
Yes. We operate as specialized conversion engineers, not your general day-to-day webmasters. We frequently collaborate with in-house developers or external design agencies. We handle the complex architectural bottlenecks, LCP optimization, and checkout friction, and provide clear documentation so your existing team can maintain the high-performance baseline moving forward.
What if we're on a highly custom theme?+
Custom themes are where our engineering approach provides the most value. Many custom builds accumulate massive technical debt over time through overlapping developer patches and deeply nested Liquid loops. Because we read raw code rather than relying on generic page builders, we surgically refactor your custom architecture without altering the frontend brand aesthetic you've invested heavily in.
What format does the audit arrive in?+
Your Revenue Leak Audit is delivered as a comprehensive, structured PDF document alongside a detailed 10-to-15-minute Loom video teardown. We open Chrome DevTools, share our screen, and visually point out the exact ghost scripts, DOM layout shifts, and server-side delays choking your funnel, quantifying each leak in estimated monthly revenue lost.
What happens after the audit — what's the next step?+
After you review the audit, we schedule a brief discovery call to discuss the findings. If we identify significant recoverable revenue, we will present a fixed-scope technical sprint to engineer the fixes. There are no high-pressure sales pitches and no endless monthly retainers. You either hire us to execute the exact technical roadmap we provided, or you hand the audit to your internal team to implement.
How do you measure CVR lift?+
We measure success mathematically, not subjectively. We track your baseline CVR, Average Order Value, and mobile bounce rates before deployment. Post-launch, we monitor the store for 30 days under normal, statistically significant traffic conditions. By ensuring ad spend and traffic sources remain relatively consistent, we can definitively prove that the infrastructure upgrades drove the revenue lift.
