36,600 at $1.78
A 12% conversion rate across 305K clicks, with cost per conversion holding at $1.78.
01 The problem
A major Nordic home and hardware retailer needed to drive both online sales and in-store visits at scale. The challenge: maintaining cost efficiency while increasing volume massively. Previous campaigns had hit a ceiling around 10K monthly conversions — the account structure wasn't built for scale, and there was no strategy connecting e-commerce and local store traffic.
Volume and efficiency, at once.
Most campaigns trade one for the other. Inventory-level bidding is the unlock that delivered both.
Shopping + Local layering
Rebuilt the account with Shopping campaigns for e-commerce and Local campaigns driving in-store traffic.
Inventory-level bidding
Automatically promoted in-stock items and suppressed out-of-stock SKUs — the right product, the right moment.
Seasonal structures
Built campaign structures for peak renovation periods, driving 40% higher conversion rates in season.
Store-visit attribution
Implemented offline attribution — revealing 22% of in-store buyers had touched a digital ad within 30 days.
Past the ceiling.

04 Why it worked
Most campaigns sacrifice efficiency for scale, or scale for efficiency. We grew volume from ~10K to 36.6K monthly conversions while the cost per conversion stayed at $1.78. The inventory-level bidding was the unlock — promoting the right products to the right people at the right moment.
We were stuck at ten thousand conversions. They got us to nearly thirty-seven thousand at the same cost each — the inventory bidding was the difference.
