About The House of Mouth
The House of Mouth is an Australian oral care and teeth whitening provider, making high-quality dental products and expert support more accessible to everyday consumers. With 800+ products from leading global brands and a personalised approach, tailored recommendations, virtual consultations, THOM has supported over 60,000 customers.
The challenge
THOM came to us with a clear goal: scale online revenue while making existing marketing work harder. The account had real budget and a huge product range, but no structure holding it together. Google Ads and Meta Ads were both running, just not talking to each other, and in a crowded oral care market, that showed up as traffic without enough conversion behind it. Standing out here meant getting more precise, not spending more, and doing it without losing control over budget or product priority during peak periods.
The strategy
We rebuilt the account around one connected strategy instead of three separate ones. On Google, Search and Performance Max worked together: tighter campaign structures improved targeting and product grouping, and Performance Max kept the product feed aligned with real-time intent so the right products showed up in front of the right people. Creative did its part too; responsive search ads tested multiple headline and description combinations to keep message match tight, while Performance Max ran a wide spread of headlines, descriptions and visuals to find what worked and reach further. During Black Friday and Cyber Monday, we moved earlier than competitors, prioritised discounted ranges, and matched messaging across Google, Meta, and email, so the whole account moved as one system instead of three channels doing their own thing.
The results
Over FY25: revenue up 109%, total orders up 78%, and average order value up 18%, all while holding a 4+ ROAS the whole way through. Not one good month. A full year of it. Beyond the numbers, THOM's marketing stopped being three channels working in isolation and became one system pulling in the same direction, a clearer path to purchase, and customers coming back, not just one good quarter.
