AI Chat Advertising Turns Discovery into Performance
In an interview, Laure Sauteraud describes how advertising inside LLM-driven chat experiences is emerging as a measurable performance channel. Criteo’s integration with OpenAI is not yet active in Germany or the EU but is available in the US, Australia, Canada, New Zealand, the UK, Japan and South Korea. The dominant format is “Prompt Smart Ads,” which adapts creatives and product descriptions to user queries. More than 2,000 brands already advertise in ChatGPT via Criteo, and Criteo reports that over 80% of ad-driven ChatGPT traffic originates from new customers. Sauteraud argues AI chat expands discovery earlier in the customer journey, enables deeper personalization from richer conversational context, and should be measured by standard business KPIs such as sales, ROAS, customer acquisition and incremental revenue.
