CEO & Founder, OneEarPod
OneEarPod sells individual replacement AirPods — left, right, or charging case — so customers don't have to buy an entirely new set when one piece breaks or goes missing. It's a simple idea that saves money and reduces electronic waste, backed by fast shipping that customers love.

We structured the engagement around two parallel workstreams: making the existing German campaigns as efficient as possible, then replicating that playbook across new European markets.
OneEarPod sells individual replacement AirPods — a simple, clever idea that saves customers money and reduces e-waste. Fast shipping and genuine quality had built them a loyal customer base in Germany.
But their paid ads had plateaued. Despite a healthy ROAS, Google wasn’t spending their daily budget. Every attempt to scale led to worse returns. They came to us with a clear constraint: grow the budget only if ROAS stays above target. No exceptions.
The core issue was structure. OneEarPod was running broad campaigns that mixed different products, intents, and match types together. Google’s algorithm had no room to optimize because everything was competing for the same budget.
We rebuilt the account from scratch. Each product got its own Search and Shopping campaign with dedicated budgets and bidding strategies. We restructured the product feed so titles and descriptions matched how people actually search — “replacement left AirPod Pro” instead of generic SKU names.
“AirPods” gets millions of searches every day — reviews, comparisons, setup guides, troubleshooting. Almost none of those people want to buy a single replacement earbud. Without aggressive filtering, OneEarPod’s budget would evaporate on clicks that never convert.
We built a negative keyword strategy that we refined weekly. Every search term report was reviewed, irrelevant queries were excluded, and the remaining budget went exclusively to high buyer-intent searches. This wasn’t a one-time setup — it was an ongoing discipline that compounded over time.
Once the German campaigns were consistently profitable and exceeding ROAS targets, we expanded. Austria came first — similar language, but different search patterns and competition. Then France, Netherlands, Belgium, Italy, and Spain.
Each market got a native-language account manager who didn’t just translate ads — they adapted messaging, landing pages, and bidding strategies for how people in that specific country search for and buy replacement AirPods. A French customer doesn’t search the same way a Dutch customer does, and our campaigns reflected that.
We layered in retargeting campaigns on Facebook and Instagram, segmented by where each visitor dropped off. Someone who viewed a product page saw different creative than someone who added to cart but didn’t check out. This kept OneEarPod visible across the entire buying journey and brought back visitors who were already interested but needed another touchpoint.
Reach customers while they compare products and decide what to buy. We build and manage your ChatGPT Ads campaigns, custom product feeds and sales tracking, so you can start learning what works for your brand.
We doubled the budget in month one, then kept scaling. By month six, ad spend was 6x the starting point and ROAS was higher than when we began.
Impression share and click share both climbed steadily. In key markets, OneEarPod moved from barely appearing to consistently winning auctions against larger brands.
Each market had native-language campaigns, localized messaging, and its own ROAS targets. All seven markets were profitable by the end of the first year.
