More revenue from your paid traffic through faster PDPs - without touching your Shopify store

I rebuild your top products as headless PDPs and measure conversion lift. Most brands see +10% minimum. Then we roll it out for all of your products. The base for more and faster experimentation.

You might know that your PDPs don't load as fast as they should. I help you quantify how much that is costing in in revenue, by A/B testing a faster version.

Why nothing else has worked

You've probably already tried the obvious things.

  • A/B testing tools aren't lying. Load times vary 20–30% session to session. That's enough variance to make most test results statistical noise. You can't optimize on a foundation that won't sit still.
  • Other CRO agency can't fix this because it lives inside Shopify. Every review widget, subscription app, and tracking script adds weight. Removing them means removing apps the business depends on. So CRO work targets copy and layout instead.
  • The team's PDP ticket has been backlogged for months. Every change to the theme risks breaking something else. That creates inertia. A parallel headless page sidesteps it - one deployment, no sprint planning, no dependencies.
How it works

A parallel page. Not a theme rebuild.

I build a parallel version of your top PDP - headless, outside Shopify's theme and app stack, with your paid ads pointing to it. Everything else - organic, email, direct - hits your main store unchanged. That setup let's us measure performance within 14 days.

Proof

Verifiable, not anecdotal.

While revenue numbers are dependent on many factors, page speed insights are easily quantifyable.

LCP 8s → 2s · PageSpeed 50 → 95

DTC brand, $30k+/mo Meta spend

Over 10% of paid Meta traffic was bouncing before the page finished loading. The product page was rebuilt headless, and the drop-off between click and page visit disappeared.

More revenue for the same spend

Fit

Who this is and isn't for.

This is for you if

  • DTC brand spending $20k+/mo on Meta or Google
  • PDP loads slower than 3s on mobile
  • You want to know exactly what your PDP speed is costing in paid traffic

Not for you if

  • Pre-revenue or no paid traffic
  • You want a full site or theme rebuild
  • You want a long-term agency relationship with monthly reporting

I spent 10 years building growth infrastructure at companies like Klarna and Grover, and realised most DTC conversion problems are page-speed problems dressed up as CRO problems. Now this is the only thing I do.
