Preparing for ChatGPT advertising in 2026 involves understanding how platforms like Microsoft Advertising are integrating large language models (LLMs) – including OpenAI’s GPT-4 – to automate ad creation and targeting, moving beyond traditional keyword-based systems.
As of December 2025, Microsoft Advertising’s AI-powered ad features, now including generative ad assets, allow advertisers to input a description of their business and target audience. The system then automatically generates multiple ad variations, headlines, and descriptions. In 2026, this functionality is expected to expand significantly, with more granular control over the LLM’s ‘voice’ and style. Currently, these features are available to Australian advertisers through the Microsoft Advertising platform, with pricing based on standard cost-per-click (CPC) models. Compliance with Australian advertising standards, including those relating to misleading or deceptive conduct, remains the advertiser’s responsibility, even with AI-generated content. Microsoft has announced in late 2025 that 2027 will see integration with more first-party data sources for improved audience segmentation.
Essentially, ChatGPT advertising leverages LLMs to automate the copywriting and testing phases of digital advertising campaigns, allowing for rapid iteration and potentially improved ad performance.
