Rocket’s SEO team has been observing and testing this shift since ChatGPT and Perplexity first launched in 2022, then Bing and Grok evolved in 2023 and AI overviews took off in 2024. One thing is certain - generative engine optimisation is not SEO and does not work the same way. So treating it like it is will lead to the wrong investments for Australian marketers.
Let’s unpack why.
AI usage in research is rising rapidly. There’s plenty of research backing this:
And this isn’t just general browsing behaviour. It’s embedded in buying journeys.
In APAC, 93% of B2B buyers report using AI to support their buying process, typically at the beginning and middle stages of the buying journey
Closer to home, the Australian data is equally telling:
If AI usage in research is rising this fast, and it clearly is, then part of your audience is no longer discovering, evaluating and shortlisting brands purely through traditional search.

The second shift is structural. AI is changing what happens before someone ever lands on a business's website. AI-generated summaries and answer layers mean zero-click behaviour is exploding:
When answers are synthesised directly in-platform, ranking second or even first isn’t the same competitive advantage it once was.
Visibility is no longer just about earning a position in a ranked list. It’s more important to be included in a summarised answer when your audience is looking for your product or service.
That’s a very different game compared to traditional SEO.

This is the critical distinction. The SEO industry has spun itself in knots over the past four years, with many saying that ranking in AI platforms like ChatGPT and Perplexity is the same as SEO. It’s just not true. Yes, there’s loads of overlap with the levers that one can pull to rank well in traditional search and the ones to pull to appear prominently in ChatGPT for a similar theme - but when to pull each lever is generally very different depending on the particular website/brand being optimised. Deploying a single strategy across both channels is typically a fast track to underperformance in one (if not both).
Search engines rank and list links, while AI systems synthesise and interpret responses.
Traditional SEO is built on signals like:
AI models, by contrast, surface content based on contextual modelling and relevance, not just keyword weightings. This is why we’re seeing research showing that:

This means nearly a third of pages cited in ChatGPT responses have no meaningful organic ranking footprint. SEO performance does not reliably predict AI visibility, and AI visibility does not require traditional SEO dominance.
This is why calling GEO “SEO 2.0” misses the point.
Another nuance that matters for marketers is that not all AI environments operate the same way.
Citation distributions differ between Google AI Overviews and ChatGPT. What works in one environment doesn’t automatically transfer to another.
In fact, optimising for one AI surface may reduce performance on another, and changes intended to influence AI responses can, in some cases, affect traditional rankings.
Your strategy cannot be copy-paste.
AI optimisation requires:
The overlap with traditional SEO does exist, but the intent and execution differ.
Before changing anything, understand:
For many industries, AI is already influencing early and mid-funnel research, especially in B2B. That means your AI strategy should start at:
Traditional SEO optimises for position. AI optimisation focuses on inclusion in summarised answers. That requires:
The goal is, when someone asks an AI tool about this topic, does our perspective get woven into the answer?
AI systems don’t simply reward page authority the way search engines historically have. They evaluate:
That means authority must be built deliberately:
One of the most important nuances is that each AI surface behaves differently. What works for Google AI Overviews may not perform the same way in ChatGPT or Perplexity. And changes made purely for AI visibility can sometimes impact traditional search performance.
So your strategy needs to:
For in-house teams, that means AI optimisation cannot sit in isolation. It must be integrated with (but not absorbed into) SEO.
Senior marketers are used to tracking rankings, impressions, CTR and conversions. AI visibility requires a different layer of monitoring:
It’s influence tracking, and in many categories, influence happens before the click.
Measuring GEO effectiveness is also fundamentally different to SEO, and this is where many teams underestimate the shift. In traditional search, platforms like Google Search Console, Semrush and Google Analytics provide clear visibility into impressions, rankings, clicks and performance over time.
In AI environments, that layer doesn’t exist. Most platforms are closed ecosystems where users consume answers in-platform, click through less and attribution is fragmented or delayed. In many cases, AI influences the discovery stage and the buyer’s consideration, but the eventual conversion happens via a different channel, making the impact easy to miss if you’re relying on last-click or standard analytics models.
That doesn’t mean GEO can’t be measured, but it does require a different mindset and toolset. Instead of tracking rankings and traffic alone, marketers need to measure inclusion, visibility and influence. At Rocket, we combine a range of approaches to build this picture, including AI visibility tools and emerging GEO platforms to track brand mentions and competitive presence, alongside custom prompt tracking to monitor how clients appear across key queries. It’s not perfect, and there’s no single source of truth yet, but together these inputs provide a reliable view of whether your brand is being surfaced, how it’s being positioned, and whether that visibility is translating into commercial impact.

SEO remains foundational. Technical excellence, authority building and content strategy are still essential, but they don’t guarantee AI coverage.
If AI inclusion were purely a byproduct of SEO, we wouldn’t see minimal correlation between classic SEO metrics and AI citation.
Search used to be a ranked list, and now it’s ranked results, AI summaries, conversational responses and multi-step prompt flows.
The mechanics are different, so the strategy must be different. If your brand isn’t positioned for inclusion in these environments, you may be invisible in parts of the buyer journey you can’t easily measure.
In 2026, your business needs a strategy for organic search, and in Australia, given 95% of market share, this is typically synonymous with Google. However, the landscape has changed and you now need a strategy and measurement plan for GEO. AI engines aren't going anywhere and they are fast becoming the starting point for millions of buyer journeys in Australia each month.
