As of December 2025, ChatGPT ad extensions allow advertisers to dynamically generate ad copy variations and conversational landing page experiences directly within platforms like Google Ads and Microsoft Advertising, leveraging OpenAI’s large language model capabilities.

Currently, these extensions work by connecting to your existing ad campaigns and product feeds. When a user searches, ChatGPT generates ad headlines and descriptions tailored to the search query, aiming for higher click-through rates. Now includes ‘Conversation Starters’ – pre-populated prompts within the ad itself, initiating a chat-like interaction. In Australia, these extensions are available through beta programs with major advertising agencies and directly to businesses spending over $20,000 AUD monthly on ad spend. Data residency and compliance with Australian Privacy Principles are managed by the advertising platform, not directly by OpenAI. In 2026, integration with more Customer Relationship Management (CRM) systems is expected, allowing for personalised ad copy based on customer data (with appropriate consent, of course). Announced for 2027 is the ability to A/B test ChatGPT-generated ad copy against traditional static copy at scale.

Essentially, ChatGPT ad extensions automate ad copy creation and enhance user engagement by providing more relevant and interactive ad experiences.
