GEO
Generative Engine Optimisation in Perth
See how Perth’s leaders in generative engine optimisation can unlock your business potential by getting more visibility from AI tools.
A new era of search visibility
What is generative engine optimisation?
At Gilligan Group, we define GEO as the work of becoming a source that generative engines trust enough to cite more frequently and more prominently. Not ranking for the question, or being listed as a source, but being named in the answer. Despite its similarities with SEO, GEO is a distinct practice with its own mechanics. This isn’t just our opinion; it’s an idea that’s been formalised by researchers from Princeton and IIT Delhi in 2024.
AI search optimisation
How GEO differs from SEO
SEO and GEO both optimise for visibility, but where SEO competes for a ranking on a search results page, GEO competes for a place inside a generated answer. For GEO, your position in the search results matters less; it’s more important that your content is structured to fit the format of LLM responses (Passage Level optimisation).
Our approach
Our GEO methodology
AI Visibility Audit
We map where AI tools cite you, where you’re missing, and whether your site is even reachable by AI crawlers.
SEO Foundations
Grounded answers pull from search rankings, so we build the rankings that make you eligible to be retrieved, across your query and its fan-out.
Content Restructure
We reshape pages so the answer sits near the top, matches the query’s intent, and reads as self-contained, fact-specific passages an engine can lift.
Authority & Entity Building
We earn third-party mentions, reviews and consistent entity signals, shaping what engines already know and trust about you before they ever search.
Monitoring & Refinement
We track citations and mentions across ChatGPT, Gemini and Perplexity, then feed what’s working back into the next round.
Where SEO influences GEO
SEO is critical to GEO, and anyone who tells you otherwise is being disingenuous. It comes down to the simple fact that tor current or factual questions, generative engines don’t rely on their training data; they retrieve fresh information from search engines like Google and Bing, a process called retrieval-augmented generation, or grounding. In other words, to be cited in grounded answers, you need to be optimising for search engines.
Why GEO matters for Australian businesses in 2026
Australians are power users of AI. Salesforce found that 49% of Australians had used generative AI as far back as 2023, compared with 45% in the United States and 29% in the United Kingdom. That share has only grown since, and for those users still using Google, AI Overviews are showing for 25% of all queries. If you’re ignoring GEO, you’re ignoring a growing audience.
What actually moves visibility in generative engines
Based on our testing, if we were to give you the two highest-impact changes you can make today, the first would be to optimise for search, as you now need to rank for not one, but a fan-out of queries. The second would be to carefully articulate your content and ground it with credible sources. This isn’t just our anecdotal experience; it’s backed by real data from experts our team trusts, like Cyrus Shepard and Rand Fishkin. But of course, it’s easier said than done. That’s where our team can help.
