Conversion optimization & rebuilds · European ecommerce

Your store already has traffic. Let’s make more of it buy.

We help European ecommerce brands earn more from the visitors they’re already paying for — through conversion optimization, and full rebuilds when the foundation won’t hold.

8–10 fixes ranked by revenue impact. No strings, no pitch.

20–40%
of store revenue typically comes from email & SMS

The problem

More ad spend won’t fix a store that leaks.

01

You’re paying for traffic that leaves

Spend on ads and SEO keeps climbing, but too many visitors land, look, and go — without ever adding to cart.

02

You suspect a leak — you can’t see where

The drop-off is somewhere between the product page and the payment step. Guessing is expensive; testing blind is worse.

03

The revenue is already yours to win

You don’t need more traffic to grow. A better-converting store earns more from the exact same visitors, at the same ad spend.

What we do

One focus: more of your traffic buys.

We lead with conversion and retention — the levers that pay for themselves — and rebuild the store only when the foundation is what’s holding you back.

Core

Conversion rate optimization

Continuous A/B testing across product pages, cart and checkout — the highest-value leaks first. You see the revenue impact, not vanity metrics.

Core

Email & SMS retention

Lifecycle flows in Klaviyo that recover carts and bring buyers back. Often 20–40% of a store’s revenue, and usually the most underserved.

Core

Paid media management

Meta, Google and TikTok spend managed to a target return — so a better-converting store compounds into cheaper acquisition.

Foundation

Store builds & rebuilds

Conversion-ready Shopify builds and replatforms, fixed scope, when the current foundation is holding sales back.

Foundation

Analytics & tracking

GA4, server-side tracking and consent mode set up properly — so every win is measurable and GDPR-compliant.

Included

Systematized delivery

An automation-driven process means standardized reporting and onboarding — faster delivery, and nothing slips through.

Sprint

We ship the highest-ROI fixes first, in a focused 2–3 week sprint — or rebuild the store when the foundation won’t hold. Cash-flow friendly, no long commitment to start.

03Monthly

Retainer

We run continuous A/B testing to compound conversion month over month. This is where the real gains — and the real relationship — live.

Why Maubourg
The visitors you’re already paying for are the cheapest growth you’ll ever buy. We just help more of them say yes.

European by focus

We work only with existing European stores — so we know your market, your buyers and your compliance obligations from the first call.

Everything is measured

You see the revenue impact of every change — “lifted conversion from X% to Y%, adding €Z/month at the same ad spend.” Never vanity metrics.

Systematized, not improvised

An automation-driven process behind the scenes means faster delivery, standardized reporting, and nothing missed.

Pricing

Priced to the revenue we lift.

Land with a teardown or one-off project, then retain with monthly optimization. Every retainer runs a 3-month minimum so tests have time to prove out.

FAQ

Questions, answered.

Is the teardown really free?+

Yes. We audit your live store and send back 8–10 fixes ranked by revenue impact, no charge and no obligation. If the fixes are worth acting on, we can talk about doing them together — but the list is yours either way.

Who do you work with?+

Existing European ecommerce brands — typically Shopify or WooCommerce stores already doing meaningful traffic and revenue. We focus on Europe so we know your market and your compliance obligations.

Do I need a rebuild?+

Usually not. We lead with conversion optimization because it earns more from the store you already have. We only recommend a rebuild or replatform when the foundation itself is what’s holding sales back.

How fast will I see results?+

The quick wins from a sprint can ship within weeks. Compounding gains come from continuous testing on a retainer — which is why we ask for a 3-month minimum, so tests have time to prove out.

How do you measure success?+

By revenue, not vanity metrics. Every change is tied to a number — conversion rate lifted, revenue added at the same ad spend. If we can’t measure it, we don’t claim it.
