The problem

Most agencies will take
your budget. Few will
take responsibility
for results.

Scaling Google Ads for eCommerce means understanding your margins, your market, and your customer — not just running campaigns.

Most agencies hand your account to a junior, report on vanity metrics, and call it a month. Impressions. Clicks. CTR. Numbers that look good in a slide and mean nothing to your bottom line.

We don't work that way. We start with your business objectives and build backwards from there — campaigns that are structured to scale, optimised relentlessly, and reported honestly.

What makes us different

The work is the
difference.

Watermouse is one senior operator by design — not a team of juniors. That keeps every account focused, accountable, and genuinely invested in.

Senior oversight, always

We run lean. Senior oversight on every account, every week — not just at onboarding and quarterly reviews.

Built for European eCommerce

We've worked across NL, UK, DE, and beyond. We understand how markets differ — in behaviour, seasonality, and competitive dynamics — and how to build campaigns that reflect that.

Outcomes, not activity

We report on revenue, ROAS, and CAC — the numbers that move your business. Not impressions, not spend. If something isn't working, you'll hear it from us first.

What we do

Google Ads, done
properly.

01
Search & Shopping

Capture demand at every stage of the funnel — from brand terms to broad commercial intent. We build and manage Search and Shopping campaigns that drive profitable revenue, not just traffic.

02
Performance Max

PMax done right requires strong feed management, clear audience signals, and constant optimisation. We know what it takes to make it work for eCommerce — not just spend the budget.

03
YouTube & Display

Upper-funnel campaigns that build awareness and retarget high-intent visitors. Integrated with your full-funnel strategy, not bolted on as an afterthought.

04
Multi-market expansion

Scaling across European markets is a different challenge. We've done it — across languages, currencies, and consumer behaviours. We help you expand without losing efficiency.

How we work

Strong foundations,
then scale.

01
Audit & diagnosis

Before we touch anything, we understand your business — your margins, your best products, your current account structure, your attribution setup. We find what's working, what's wasting budget, and where the biggest opportunities are.

Week 1
02
Foundation build

We restructure or rebuild your account from the ground up. Clean structure, proper feed management, accurate tracking and attribution. This is the work most agencies skip — it's also what makes everything else work.

Weeks 2–3
03
Test & optimise

We run structured tests — bids, audiences, creatives, match types — and optimise based on what the data shows. No hunches. No set-and-forget. Continuous, deliberate improvement every week.

Month 1–2
04
Scale what works

Once we know what converts profitably, we scale it deliberately — more budget, new markets, expanded campaigns. Growth that compounds, not spikes that disappear.

Paying too much?

Switching from your current agency or freelancer?

Most European eCommerce brands overpay for Google Ads — €3,000–€8,000/month to a large agency where a junior actually runs the account, or a full-time hire at €60k+/year. Watermouse is a cheaper alternative to a traditional Google Ads agency — without going offshore or cutting corners. You get senior, EU-experienced management directly, at a lower cost structure: typically a fraction of what an EU agency charges. Same seniority, none of the overhead.

What you're likely paying now
  • €3k–€8k/mo to a large EU agency
  • A junior on the account; the senior you signed with shows up quarterly
  • Reports full of impressions and clicks, not revenue
With Watermouse
  • €1,500–€4,000/mo — often around half the cost
  • One senior operator on your account directly, every week
  • Reporting on revenue, ROAS and CAC — the numbers that matter
Switching is clean
  • Full audit of your existing account first
  • We keep what works, fix what doesn't
  • Managed transition — no performance gap, no lost history
