De One Performance Want this to sell with paid media too? Our paid media & e-commerce unit: over $1,000M managed per year.

E-commerce? Our home turf

Create, migrate or improve: three paths, one obsession with sales.

Create from scratch

Your first store, born right: the correct platform, measurement installed and a catalog ready for ads.

Selling in weeks, not months.

Migrate without pain

We move your store between platforms without losing SEO, customers or history. Planned and tested migration.

Zero traffic drops.

Improve the one you have

CRO audit: speed, checkout and the friction scaring buyers away.

Sometimes +30% conversion is already in your store, trapped.

Why build it with us

Because we are not a web shop: we are the agency that makes it sell afterwards.

Born measuring: GA4, pixels and Conversions API installed from day one, not patched in later.

Born to sell: speed, optimized checkout and CRO applied from the design stage, not fixed later.

Born connected: CRM, WhatsApp and email ready to build repurchase from the first sale.

And with the team that runs it afterwards: the same house managing over $1,000M a year in ads knows exactly what converts.

Frequently asked questions

How long does a web project take?

A landing page can be live in a couple of weeks. A full e-commerce usually takes one to two months depending on scope. You get a clear timeline before we start.

Can I manage the site myself?

Yes. We deliver it with an admin panel, train you and leave documentation. Or we can manage it for you.

What happens to my current site?

We audit it and migrate content and rankings without losing SEO. You notice the change in design and speed, not in lost traffic.

Will the site actually sell?

That's the point. We build it measurable and connected, and with De One Performance we add paid media and optimization to turn it into a sales channel.
