How does ChatGPT decide what to recommend?

Expert Summary
ChatGPT doesn’t just rely on its training data; it scrapes current search results. If Google decides a specific URL is the “canonical” master version of your content, that’s what ChatGPT recommends. For Australian SMEs in 2026, AI visibility is largely a byproduct of Google’s indexing decisions.

The Situation in 2026
Customer acquisition costs have peaked, and the “zero-click” trend is stealing traffic. Australian business owners are seeing leads drop because users get their answers directly inside the AI interface, ending their journey without ever clicking through to a website.

Key Considerations

  • Google Index Reliance: Our observations show ChatGPT effectively scrapes Google results. If Google ignores your “rel canonical” tags and chooses a different version of your page as the primary one, the AI will surface that version. You lose control over which landing page handles the lead.
  • The Zero-Click Destination: AI responses are becoming the final stop for the user. Traditional click-through rates (CTR) are dying metrics. The new goal is “mention share” — ensuring your brand is the one cited in the answer, even if the user doesn’t visit your site.
  • Visibility Gaps: Most brands are flying blind. They show up in thousands of AI responses but have no idea which queries trigger them or how their positioning stacks up against a competitor. You cannot optimise what you aren’t measuring.
  • Model Specialisation: Not all AI is the same. While ChatGPT is efficient for rapid ideation and social hooks, it lacks the nuanced context handling of models like Claude. If your content is generic, you are easily displaced in the recommendation engine by a competitor providing deeper, more structured data.

ROI and Growth Perspective
ROI Growth Agency views this shift as a move from traffic volume to recommendation authority. Stop obsessing over raw hits and start using tools like Semrush to identify AI visibility gaps. The fastest way to win is to ensure your technical SEO is tight so Google—and by extension, ChatGPT—indexes the correct, high-converting version of your offer.
