The brief
GAS4U is an Irish-owned CO2 refill service based in Sandyford, Dublin, delivering to households across Ireland. Customers buy refill cylinders for their home sparkling water makers as a one-off or through the refill club subscription, and send the empties back for free.
Two things shape the marketing. First, the value is in the subscription: a customer who joins the refill club is worth far more than a single order, so we judge campaigns on lifetime value rather than first sale. Second, the range is small on purpose, two cylinder types that fit most home machines, but customers don't search for a cylinder type. They search for their own machine and the refill it needs.
Google Shopping and paid search
- Set up GAS4U's Google Merchant Center account, which now also brings in sales from free organic Shopping listings.
- Performance Max campaigns with a heavy focus on Shopping.
- Campaigns split between the refill club and SodaStream-specific searches.
- Now moving into machine-level campaigns that use the new machine-specific content.
Building the brand
Demand Gen campaigns raise awareness of GAS4U, so more people search for the brand by name. In the three months to October 2026, compared with the three months before, Google Search Console shows clicks from branded searches up 60% and branded impressions up 40%.
SEO for every machine
We have made extensive SEO changes to the Shopify website to expand a two-product range into machine-specific refill content, so GAS4U can answer the exact search a customer makes for their machine, in Google and in AI search tools. The changes are live and we will add results here as they come through.
Where it stands
We started working with GAS4U in June 2026. The groundwork is in place: Merchant Center and organic Shopping, a growing branded search audience, and machine-level content and campaigns. The focus now is turning new customers into refill club members.
