A Google Ads account burning money

When Dollarstore.dk contacted us, they had been running Google Ads for over 2 years — but the numbers didn't add up. ROAS sat at 232%, barely covering product margins, and CPA had nearly doubled over 6 months.

Unstructured account setup

247 keywords in one campaign, no negative lists, and all products lumped together in one Shopping group.

Broken conversion tracking

GA4 and Google Ads conversions didn't match. Half of all sales were never recorded correctly.

No feed optimization

The product feed was generic, with no optimized titles or relevant attributes. Result: poor visibility in Shopping.

Performance Max without control

Pmax campaigns ran without asset groups or brand exclusions. They cannibalized Search and wasted budget on brand searches.

A 3-phase plan to restructure and scale

We didn't start by running more campaigns. We started by cleaning up. Here is the phased plan we followed — one that has proven to work for 20+ other Danish companies.

01

Foundation: Cleanup & correct tracking

Week 1-2

Before touching the strategy, the foundation had to be in order. We spent the first two weeks reviewing and rebuilding everything technical.

Pause all ineffective campaigns
GA4 + Google Ads tracking re-implemented
Enhanced Conversions activated
Merchant Center feed setup revised
02

Build: New campaign structure

Week 3-6

With a solid foundation, we built the campaigns from scratch — this time with a clear structure based on product types, margins and search intent.

Segmented Shopping by product category
Search campaigns with strict match types
Pmax with audience signals & exclusions
Brand campaign separated from Pmax
03

Scale: Systematic budget expansion

Week 7-24

Once the target ROAS was hit and stabilized, we began scaling. Not by throwing money at the problem — but by identifying the campaigns that scaled best.

Gradual budget expansion 20-30% per week
Load-up for Ramadan campaigns (seasonal)
Remarketing lists activated
Creative A/B testing of Pmax assets

The concrete optimizations that moved the needle

Strategy is only half of it. Here are the 6 concrete actions that actually moved ROAS from 232% to 650%.

Negative keyword cleanup

Built a comprehensive negative list of 400+ keywords. Result: 38% less wasted spend on irrelevant clicks in the very first month.

Feed optimization

Rewrote 1,000+ product titles, added attributes and categorized everything correctly. Shopping visibility increased 280% over 3 months.

Budget reallocation

Moved 65% of the budget from ineffective Search campaigns to Shopping and Pmax — where ROAS was 4x higher.

Pmax audience signals

Fed Pmax with customer lists, remarketing and interest groups. The algorithm learned faster and CPA dropped 42% in Pmax.

Enhanced Conversions

Implemented Enhanced Conversions via sGTM. Result: 32% more matched conversions — the algorithm got precise data.

Seasonal scaling

Built dedicated Ramadan campaigns with tailored ads and feeds. Result: 900% traffic growth during peak season.

The numbers before and after

Six months after the partnership started, we had turned the account from burning budget into one of Dollarstore's strongest growth engines.

3 things we learned from the Dollarstore case

01

Foundation beats strategy

The world's best campaign strategy doesn't work without correct tracking and a clean account structure. Fix the foundation first.

02

Pmax is powerful — when you control it

Performance Max can deliver enormous volume, but without audience signals, asset groups and brand exclusions it just burns budget.

03

Scaling requires patience

We increased budget 20-30% per week — not 200% all at once. The algorithm needs time to learn, and rapid changes destroy performance.
