How to optimise a website for ChatGPT search?

Expert Summary
Stop chasing keywords and start building credibility. Optimise for trust and structure by using verified ABNs, schema markup, and natural, question-based content. In 2026, visibility isn’t about ranking first—it’s about being the cited authority when ChatGPT recommends an Australian provider to a high-intent buyer.

The Situation in 2026
Rising customer acquisition costs and AI-led search disruption have made traditional SEO less reliable. Australian business owners are facing a “zero-click” reality where LLMs synthesise answers and recommend brands directly, bypassing the website entirely unless the business has established clear AI-readiness.

Key Considerations

  • Schema Markup: Implement local business schema including your ABN and physical address. This removes ambiguity for AI models, ensuring you’re identified as a legitimate Australian entity. Without this, you’re just another URL in a global pool, reducing your chance of appearing in region-specific AI queries.
  • Natural Language FAQs: Move away from keyword-dense headers toward direct questions and answers. AI models synthesise responses based on intent; if your content doesn’t answer the user’s prompt in a human-like way, ChatGPT will simply cite a competitor who has.
  • Verified Authority: Focus on authentic reviews and verified professional profiles rather than polished brochures. In our client work, we’ve found that AI models weigh third-party verification and trust signals more heavily than self-proclaimed expertise when choosing which brand to recommend.
  • Canonical Management: Stop treating rel=”canonical” as a rule. We’ve observed Google frequently ignoring these hints, and since ChatGPT often surfaces Google’s canonical choices, you risk the AI citing the wrong version of your content if your internal site structure is messy.
