Our Technical Services

Revenue Engineering for
High-Volume Shopify Stores.

We don't sell hours — we sell infrastructure performance. Our Shopify conversion rate optimization services are built to surgically eliminate technical debt and scale your revenue. Every engagement starts with a Revenue Leak Audit. No guesswork.

Shopify Speed Optimization

Ghost code elimination, Liquid refactoring, and Core Web Vitals engineering. We don't just compress images — we refactor your theme's architectural bottlenecks to target LCP under 1.5s. This is the foundation of improving your Shopify conversion rate for stores where every millisecond equals thousands in lost revenue.

Typical result: LCP under 1.2s, 15–25% mobile CVR lift within 21 days.

✓ Ghost app script audit & removal
✓ Liquid template refactoring
✓ Image optimization pipeline
✓ Third-party script management
✓ Core Web Vitals to target thresholds

The Difference

Why Technical CRO Beats
Generic CRO Every Time.

Generic CRO agencies

✕ A/B test button colors and headlines
✕ Install more apps (adding more JavaScript bloat)
✕ Recommend redesigns that take months
✕ Report on "improvements" with no revenue tie
✕ Miss the root cause entirely — infrastructure

Webulux technical CRO

✓ Remove the dead code killing your mobile speed
✓ Refactor Liquid templates at the architecture level
✓ Fix results in days, not redesign cycles of months
✓ Every change tied to CVR, AOV, and ROAS impact
✓ Address root technical cause — not surface symptoms

Our clients average a +22% CVR lift within 21 days — not from redesigns, but from fixing the technical infrastructure already under their store.

Who We Work With

Built for Stores Where Performance
Is a Revenue Problem.

Our Shopify CRO servicesare not for every store. They're built for brands where the gap between current performance and potential performance is costing real money — and where the fix requires engineering, not marketing.

You're the right fit if:

• Your mobile LCP is over 2.5 seconds
• Your CVR is flat despite increasing ad spend
• You've installed and uninstalled more than 10 Shopify apps
• Your checkout abandonment rate is above 70%
• You're spending $30k–$200k/month on paid acquisition
• You've tried CRO before and saw no lasting results

What you can expect:

✓ A free audit within 48 hours of applying
✓ Specific revenue leak numbers — not vague recommendations
✓ Engineering-level fixes, not theme tweaks
✓ Measurable CVR improvement within 21 days
✓ Full transparency on what changed and why

Common Questions

Shopify CRO Services:
Your Questions Answered.

What Shopify CRO services does Webulux offer?+

Webulux offers three technical Shopify CRO services: Speed Optimization (ghost script removal, Core Web Vitals engineering, Liquid refactoring), Conversion Engineering (checkout friction mapping, A/B testing, mobile funnel rebuild), and Headless Performance (Next.js storefront builds for sub-500ms page loads). Every engagement begins with a free Revenue Leak Audit — no commitment required.

How much do Shopify CRO services cost?+

Speed Optimization and Conversion Engineering are project-based with custom quotes determined after your free audit. The CRO Performance Retainer starts at $6k/month for brands scaling past $100k/month on ads. We don't publish fixed pricing because the scope depends on the specific technical issues found in your store — your audit will include a cost estimate.

Do I need to redesign my Shopify store to improve conversions?+

No. Webulux's entire approach is built around improving your conversion rate without a redesign. We work inside your existing Shopify infrastructure — refactoring Liquid code, removing dead scripts, and optimizing checkout flows. Our clients average +22% CVR lift with zero visual redesign. A full rebuild is only recommended when headless architecture is the right engineering solution.

How is Shopify Speed Optimization different from just running Lighthouse?+

Lighthouse gives you a score and a generic list. We give you an engineering fix. Our Shopify speed optimization process involves manually reading your Liquid code to find ghost scripts, redundant render-blocking resources, and architectural bottlenecks that Lighthouse can't surface. Then we fix them directly — not recommend plugins to install.

When does a Shopify store need headless architecture?+

When native Shopify has hit its performance ceiling and no amount of Liquid refactoring can get you below 2s LCP. This typically applies to stores with large catalogs (1,000+ SKUs), complex personalization needs, or brands where sub-500ms page loads are a competitive requirement. Our headless builds use Next.js with the Shopify Storefront API.

What's included in the free Revenue Leak Audit?+

The audit includes: a 24-point manual technical teardown of your store's Liquid code and app stack, ghost script detection with exact file sizes and load-time impact, Core Web Vitals analysis with estimated revenue impact per issue, mobile checkout friction mapping with drop-off points identified, and a prioritized fix roadmap. Delivered within 48 hours. No automated tools — every finding is manually verified by our engineering team.
