We go through your complete store — the user flow, cart, checkout, and speed. We find exactly where visitors are dropping off and why. Then our CRO engineers build a specific action plan to fix it and get your store converting the way your product deserves.
Trusted by Shopify Plus brands spending $30k to $200k per month on marketing. We find the gaps where your revenue is draining without any sales to show for it.
Founder & Software Engineer
I have been working in tech for around 8 years. In that time I have worked with a lot of different technologies and a lot of different clients. I did CRO work for quite a few of them, and one of them said to me: "Why not build your own brand around this?"
So here we are.
Webulux is built by engineers. We know a thing or two about Shopify and how eCommerce actually works under the hood. We also work closely with marketers and SEO experts so our clients get more than they came for.
This is not a corporate agency where you wait two days for an email reply. We build real relationships. You can reach us directly and our normal response time is under 30 minutes.
Just reviewed the Webulux audit. They found 847kb of dead JavaScript from those old inventory apps we deleted last year. We deployed their refactored Liquid code Tuesday—mobile CVR is already up 31%. No redesign needed. The math on this is brutal.
LCP dropped from 4.8s to 1.2s after Webulux surgically removed the ghost scripts and fixed the layout shifts. Cart abandonment dropped overnight. Finally, an agency that actually writes code instead of installing popups.
We are engineers, not a marketing agency. Our Shopify conversion rate optimization process needs full access to your store's Liquid code, app stack, and performance data. That level of access only works when there is real trust on both sides and when the client understands what we are doing and why.
We choose our clients carefully based on their store size, their goals, and their mindset. If you want data-driven engineering fixes, you are in the right place.
Most clients I have worked with have great creatives and solid marketing strategies. The problem shows up the moment that click lands on the website.
Most CRO agencies try to fix this the old-school way. Aggressive popups that annoy visitors. Endless A/B tests on button colors. Installing yet another app to solve one small thing. But if your mobile store takes 4.8 seconds to load, your ROAS is gone before the customer even sees your product.
Ask yourself honestly: would you wait 5 seconds for a page to load and then buy? Or would you just go find it somewhere else?
The root cause is almost always technical. And a technical problem needs a technical fix, not a marketing one.
Every Shopify app you have ever installed, including the ones you deleted months ago, leaves behind dead JavaScript and Liquid code. This invisible leftover code slows your store down, especially on mobile, and quietly destroys your Largest Contentful Paint score. On average, a Shopify store that has been live for two years carries between 300 and 900kb of unused scripts. Every single one is actively hurting your conversion rate.
Traffic is coming to your store but carts are sitting empty. We look at the invisible technical layout shifts and friction points that cause high-intent buyers to stop mid-checkout and leave. One unexpected element jumping on screen at the wrong moment costs more revenue per month than most brands spend on all their CRO tools combined.
Shopify has a performance ceiling. When you hit it, spending more on ads does not fix the problem. It just scales your losses. Real Shopify conversion optimization means refactoring the Liquid code that controls your funnel, or in some cases, moving to a headless architecture that can handle the load without slowing down.
Every Webulux engagement follows the same focused process. No endless audits. No guesswork. We do one deep frontend and backend review and then we get to work. Three phases, data at every step, revenue lift at the end.
We manually scan your entire store from the UI down to the backend. No AI checklists. No generic reports. We go through your Liquid code, app scripts, Core Web Vitals, and checkout flow to build a precise Revenue Leak Report. Every finding is measured. We show you exactly what each issue is costing you per month, ranked by impact.
We remove all the unused code safely. Dead JavaScript, leftover Liquid from deleted apps, redundant scripts — gone, without breaking anything on your live store. Then we rebuild what needs rebuilding. Checkout flows are reconstructed to remove layout shifts. LCP is targeted to under 1.5 seconds.
Every line of code we touch is tied to one goal: more revenue. You see exactly what changed, and you see the numbers — conversion rate, average order value, ROAS. We do not report on improvements. We report on money. Then we monitor for 30 days after launch to make sure the lift holds, and we keep working with you from there.
Enter your monthly visitors, your current conversion rate, and your average order value. We will show you exactly how much revenue technical friction is costing you right now based on our average 22% engineering lift.
Most Shopify Plus stores sit between a 1.4% and 2.5% conversion rate. Stores with unresolved technical debt like ghost scripts, slow LCP, and layout shifts usually sit 0.5 to 1.2% below where they should be. At an $85 average order value and 100,000 monthly visitors, that gap is between $33,000 and $100,000 in revenue you could be recovering every single month. That is not a marketing problem. That is an engineering problem.

Some stores need a slightly different approach, but the engineering foundation is always the same. Our clients keep working with us because the results hold.
“Results started showing within the first week. Webulux found technical issues we didn't know existed and our sales increased 80% within two months.”
“The speed optimization sprint was flawless. They removed over 800kb of dead ghost scripts from apps we had deleted years ago. Our LCP dropped from 5.2s to 1.1s and our bounce rate on mobile dropped overnight. We had no idea deleted apps were still loading JavaScript on every page.”
“Our store had been live for four years and we had installed and deleted at least 20 apps over that time. Webulux found 620kb of dead JavaScript still loading on every single page. After removal our LCP went from 5.1s to 1.4s. Revenue that month was up 107%. The math on this is brutal. We had been losing money for years.”
“I was skeptical that page speed was our problem. Our ads were converting fine on desktop. Webulux showed me that 74% of our traffic was mobile and our mobile LCP was 4.1 seconds. After their Liquid refactor it dropped to 1.3 seconds. Mobile revenue went up 44% in 30 days. I wish I had done this two years ago.”
Engineered progressive asset delivery for 4K visuals, built a native ring configurator, and matched landing page architecture to ad intent.
Purged ghost scripts, built a native flavor selector, and engineered a high-converting cart drawer to drop LCP to 1.4 seconds and double revenue.
Restructured variant architecture, replaced 13 bloated apps with native Liquid components, and reduced LCP from 6 seconds to under 1 second.
Every engagement starts with a Revenue Leak Audit. No guesswork — only engineering backed by data. Our three core Shopify conversion rate optimization services address the most impactful revenue leaks.
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.

Walnut and oak weren't variants. They were two separate products, two separate URLs, and two separate reasons a customer's shopping session kept restarting itself. Here's the exact mechanism behind why fragmented catalogs kill CVR, and the diagnostic framework that took one brand's LCP from 6 seconds to under 1.

A $6,000 diamond needs a 360 viewer and 4K photography to sell. That same imagery, built wrong, is the exact reason the page never loads long enough for a buyer to see it. Here's the engineering behind solving both problems at once, with the exact diagnostic sequence and loading order we used to take a diamond brand from zero to $50k a month.

Three brands. Three different products. Three different agencies had already tried and failed. Every case looked like a different problem on the surface: a moving payment button, a frozen browser tab, a checkout that just felt slow. Underneath, it was the same root cause every time. Here's the exact diagnostic process, the wrong turns, and the numbers behind recovering over $150,000 a month across three checkout rebuilds.
