Case Study: How We Scaled a Supplement Brand to a 1130% ROAS

Discover how we helped a supplement brand in the Netherlands and Belgium hit a massive 1130% ROAS using Google Ads.

Case Study: How We Scaled a Supplement Brand to a 1130% ROAS in the Netherlands & Belgium Using Google Ads

Markets: Netherlands & Belgium
Agency: Robronic Media
Channel Used: Google Ads (Search, Shopping, Display, YouTube)
Results: €290,000+ in revenue from €25,000 ad spend in February
Key Metric: ROAS 11.3


1.1 The Challenge: Unorganized Accounts, Missed Opportunities

When this established supplement brand reached out to us, their Google Ads account was a tangled mess.

They had worked with another agency, but campaigns were disorganized. Cold and warm audiences were lumped together, making it impossible to track what was really working. Their primary focus had been on social media advertising, but they were missing the power of Google’s high-intent traffic.

Their goal?

  • Profit-first scaling

  • A stable acquisition strategy for cold traffic

  • Reliable data for business decisions

It was clear: they needed structure, strategy, and clarity. So we rolled up our sleeves.


1.2 The Strategy: Our 4-Phase Google Ads Game Plan

1.2.1 Rebuilding the Foundation: Tracking, Segmentation & Setup

We started by:

  • Fixing the tracking: Switched to Triple Whale for 90%+ accuracy.

  • Cleaning up their ad account: Separated cold, warm, and hot audiences.

  • Setting up their tech stack: Integrated GA4, Shopify, Funnelish, and Google Merchant Center.

Why it mattered: Without accurate data, we’d be flying blind. This setup gave us the visibility to make informed decisions from day one.

If you can’t measure it, you can’t improve it.” — Peter Drucker

1.2.2 Cold Traffic Acquisition: Warming Up New Prospects

Once the foundations were solid, we launched campaigns targeting cold traffic through:

  • Search & Shopping ads: Based on high-intent keywords.

  • Display & YouTube: To expand reach and generate brand awareness.

We tailored product titles and descriptions based on actual search intent—so the right people found exactly what they were looking for.

Result: In just February, we acquired 4,400+ orders with a €5.80 average cost per conversion.

1.2.3 Warm Traffic Optimization: Capture the ‘Almost’ Buyers

Next, we tackled warm traffic—people already familiar with the brand or product types.

We launched:

  • Brand name campaigns

  • Competitor name campaigns

This helped us intercept users who might’ve gone with another brand, putting our client front and center when it mattered most.

Tactic tip: Bidding on competitor names legally grabs traffic from people looking for similar solutions.

In the age of distraction, be the one who shows up where attention already exists.”

 

1.3 Hot Traffic & Repeat Buyers: Maximizing Lifetime Value

We didn’t stop at the first sale. We added layers to pull people back in:

  • Dynamic remarketing ads

  • Subscription funnels on Funnelish

  • A/B tested upsells and advertorials

This helped increase average order value and customer retention.

No guesswork. Just clarity.

  • Twice-weekly updates (performance + strategy)

  • Asset sharing

  • Real-time reporting

This built trust and gave the client full transparency—without needing to log into Google Ads ever again.

1.6 The Results: ROAS 11.3 and €290K in Revenue

With just €25K in ad spend, the client saw:

  • €290,000+ in revenue

  • ROAS: 11.3

  • €5.80 cost per conversion

These profits were reinvested into stock, staffing, and expansion into other European markets.
