Google Ads for NZ ecommerce brands. built around your margins, not your ROAS.

We work exclusively with online stores. Every campaign we build is structured around your product margins, your SKU profitability, and what your business can actually afford to pay to acquire a customer.

Already running ads

Spend is going out. Margin isn't moving.

Your campaigns are active and ROAS looks reasonable — but when you subtract product cost, fulfilment and ad spend, the contribution isn't there. You're not sure which SKUs are actually worth backing, whether your feed is costing you visibility, or why scaling spend doesn't seem to scale profit. We'll audit your account and give you a straight answer — no obligation to work together.

You want to build it right before you spend.

Google Ads done badly is one of the fastest ways to burn through an ecommerce budget. Done well, it puts your products in front of shoppers actively looking for them — at a cost that makes sense given your margins. Before a dollar goes out, we map your SKU profitability, set your POAS targets, and structure campaigns around what your store can genuinely afford to pay to win a customer.

Starting from scratch

Our Methodology

How we actually run your account.

We work exclusively with ecommerce brands — so every step is designed around the realities of running an online store. This is exactly what we do, in the order we do it.

01

Find & eliminate wasted spend

A full audit of your search terms, negative keyword lists, and campaign structure to identify exactly where budget is leaking — and what's been quietly draining spend without returning margin.

02

Optimise your product feed

Your feed is the foundation of Shopping and PMax performance. We fix titles, descriptions, custom labels, and category mapping so your products show up for the right searches at the right cost.

03

Build margin-led campaign architecture

Campaigns structured by product margin tier, SKU role, and buyer intent — not just product category. Every dollar gets directed to where it has the best chance of returning a profit, not just a conversion.

04

Deploy PMax the right way

Performance Max with curated asset groups, audience signals, and product exclusions built around your margins. Not the black-box default setup Google steers you toward — one that works for your business.

05

Align bids to your actual contribution

Smart bidding strategies set against your real contribution margins — not platform-recommended ROAS targets that optimise for revenue. Bids that reflect what a profitable order actually looks like for your store.

06

Report on what actually matters

Weekly reporting on POAS, contribution, and SKU-level performance — not impressions and click-through rates. You'll always know which products are earning their budget and exactly what we're doing about the ones that aren't.

Tracking & Measurement

If the data is wrong,
every decision built on it is wrong.

Most ecommerce accounts we audit have tracking gaps that silently distort every campaign decision. Before we optimise anything, we fix the measurement layer — because Smart Bidding is only as good as the signals you feed it.

The honest reality: Most Google Ads accounts are running on modelled conversion data without knowing it. That means Google’s Smart Bidding is making bid decisions based on estimated behaviour — not actual purchases. Here’s what we put in place before we trust any number.

Google Enhanced Conversions

Standard Google conversion tags rely on cookies — which are increasingly blocked or lost. We implement Enhanced Conversions using hashed first-party customer data sent server-side, so Smart Bidding receives accurate purchase signals and makes bid decisions based on what's actually happening — not Google's modelled estimates.

Google Tag & Feed-Level Conversion Tracking

We audit your Google Tag setup and verify that Shopping and PMax campaigns are receiving accurate product-level conversion data — including revenue values, SKU identifiers and transaction IDs. Without this, Google's algorithm can't distinguish which products are driving profitable purchases versus high-volume low-margin ones.

GA4 Ecommerce Event Tracking

A clean GA4 setup with full ecommerce event tracking — purchase, add-to-cart, checkout steps — integrated with your Shopify or WooCommerce store. One neutral source of truth across every channel, so you're not reconciling three different numbers from three different dashboards when trying to understand what's working.

Blended Attribution & Backend Reconciliation

We cross-reference what Google reports against your actual Shopify or WooCommerce backend orders. Platform ROAS is a starting point, not the answer. We track contribution margin by channel so you know what each dollar is genuinely returning — not what Google is claiming credit for after the fact.

How We Measure It

The numbers that actually matter.

ROAS tells you what revenue came in. These five numbers tell you whether your store is actually more profitable. Every Google Ads decision we make — which products to back, how much to bid, where to cut — connects back to at least one of them.

01

CAC

What it truly costs to win one customer

02

Conversion Rate

How well your store turns visitors into buyers

03

AOV

The average order value per transaction

04

Contribution

Revenue minus COGS, fulfilment and ad spend

05

ltv

The long-term value of a customer to your business

What to Expect

Honest about what we can do

Google Ads isn’t a magic lever for ecommerce growth. But when it’s built around your actual product economics — the right SKUs, the right margins, the right bids — it becomes one of the most predictable acquisition channels an online store can run.

The first month is about getting your account store-ready

We don't call anything a result until the structure earns it. That means a clean product feed, campaigns organised by margin tier, and bids aligned to what your store can afford to pay per acquisition — before we touch performance.

You'll know which products are pulling their weight

Weekly reporting focused on POAS and contribution — not impressions or click-through rates. You'll see exactly which SKUs are worth backing with budget, which ones are draining spend, and what we're doing about it.

By week 12, your account reflects your business

Not generic campaigns — an acquisition system built around your catalogue, your margins, and your customer lifetime value. One that gets more efficient the longer it runs, and compounds as your store grows.

No lock-in contracts

Month-to-month. Leave any time.

You own the account

Always. No handover issues.

No hidden fees

One flat management fee. That's it.

Direct access

You talk to the people doing the work.
