STM AGENCY has launched its ChatGPT Ads service, giving UK brands an early opportunity to test advertising inside AI-led conversations as the platform enters beta in the UK.
With 900 million weekly active users globally, ChatGPT is becoming an increasingly important part of the research journey, with people using the platform to compare brands and products, ask for recommendations and make decisions before they reach a search engine or website.
For brands, this creates a new point of influence. ChatGPT Ads offer a way to appear earlier in the customer journey, while people are actively exploring what they need, who to trust and what to do next.
The new service sits within STM REACH, the agency’s performance marketing team, and has been developed to help brands test ChatGPT Ads in a structured, measured and commercially sensible way.
Through STM AGENCY’s media partnership with StackAdapt, the agency can support brands with access to ChatGPT Ads, as well as campaign planning, creative development, launch, tracking and performance analysis.
STM AGENCY will support clients across the full testing process, including media planning, prompt and keyword strategy, creative development, budget planning, campaign setup and performance measurement. The agency will also help brands look beyond clicks, with a focus on assisted conversions, branded search impact and wider discovery behaviour.
The service is designed for brands that want to test early, learn quickly and build an advantage before the channel becomes more mature and competitive.
Holly Duffy, Head of Performance Marketing at STM AGENCY, said:
“ChatGPT Ads mark a real shift in how brands can reach people during the decision-making process. This is not about replacing paid search or social, but about understanding where discovery is moving and how brands can show up in a more useful, relevant way."
"Our role is to help clients approach the channel with discipline. That means clear testing phases, sensible budgets, strong creative, proper measurement and honest recommendations on whether to scale. The brands that learn early will be in a stronger position as AI-led discovery continues to grow.”
STM AGENCY is recommending ChatGPT Ads for brands with considered purchase journeys, clear points of difference and the appetite to invest in learning. This includes sectors where people naturally research, compare and ask for recommendations before making a decision.
The agency believes ChatGPT Ads should currently be viewed as an upstream influence channel, not a direct replacement for established search or paid media activity.
STM is also advising caution for brands with very short-term sales targets, limited test budgets or highly restricted creative requirements, where early-stage channel volatility may be harder to justify.
The launch follows STM AGENCY’s ongoing focus on AI visibility, performance marketing and future-facing digital strategy, helping clients understand how changing search behaviour is reshaping the way people discover brands online.
Brands interested in testing ChatGPT Ads can speak to STM AGENCY about suitability, recommended budget levels, campaign planning and how the channel could support their wider performance strategy.
