AI SEO Perth: Research, Data & Guides to AI Search Visibility
AI SEO Perth monitors and documents how AI-assisted search affects businesses in Perth, Western Australia. It records how systems such as ChatGPT, Google AI Overviews, Gemini and Perplexity retrieve, cite and recommend sources for Perth prompts, publishes the definitions and methodology behind that work, and releases the data as it is collected.
A research and reference publication published by Search Scope. Methodology v1.0, updated 2026-09-09.
What is AI SEO in Perth?
AI SEO in Perth is the practice of making a Perth, Western Australia business visible to AI-assisted search: the systems, such as ChatGPT, Google AI Overviews, Gemini and Perplexity, that retrieve sources and compose an answer instead of listing links. It covers whether those systems can reach a site, identify the business, retrieve the right passage, and cite or recommend it when someone asks a Perth question.
The term is used loosely in the market. Generative Engine Optimisation and Answer Engine Optimisation describe overlapping ideas, and this publication keeps a reference definition of AI SEO alongside separate entries for GEO and AEO so the terms stay distinguishable. What none of them means is control over an AI system's output. The documented levers are access, identity, retrievable content and corroboration; whether a given answer names a given business is something to observe, not promise.
What the publication tracks
One observation record per prompt, per platform, per run. These are the fields every study records; counts appear only once a study has data.
| Tracked | What is recorded |
|---|---|
| Brand mentions | Every business named in an answer, recommended or not. |
| Recommendations | Brands presented as a shortlist, in the order given. |
| Cited domains | The domains behind each citation, classified by source type. |
| Cited URLs | The exact pages cited, so recurring source pages surface. |
| Source overlap | Which sources recur across prompts, platforms and runs. |
| Platform differences | One prompt set, every platform in scope, compared side by side. |
| Query and prompt classes | Informational, commercial, comparison, recommendation, local, brand, competitor, trust-validation. |
| Change over time | Repeated rounds on a fixed prompt set so movement is measured, not assumed. |
Perth AI search observatory
The research programme runs a fixed set of Perth prompts across each platform in scope, repeats every prompt, and records who was named, who was recommended and what was cited. Repetition is the point: a single answer is an anecdote, a frequency across runs is an observation.

Gemini SEO: how Gemini grounds answers and what Google-Extended controls
Gemini SEO defined through Google's documentation: some Gemini responses are grounded on Search results, Google-Extended controls training and grounding for Gemini apps without affecting Search, and Gemini is a different surface from AI Overviews and AI Mode. What that means for a Perth business.

Core definitions
Each definition opens its own reference page with a standalone answer, key facts and sources.
- AI SEO
- AI SEO is the practice of making a business visible to AI-assisted search: systems such as ChatGPT, Google AI Overviews, Gemini and Perplexity that retrieve sources and compose an answer rather than listing links. It covers whether those systems can reach a site, identify the business, retrieve the right passage and cite or recommend it. In Perth, Western Australia, that means being one of the sources an assistant draws on when someone asks a Perth question.
- Generative Engine Optimisation
- Generative Engine Optimisation (GEO) is the practice of improving how visible a source is in the answers composed by generative engines, the search systems that use a large language model to synthesise a response with citations. The term was introduced in a 2023 research paper that tested content changes against a benchmark of queries. In practice GEO overlaps almost entirely with AI SEO; the difference is origin and emphasis, not mechanism.
- Answer Engine Optimisation
- Answer Engine Optimisation (AEO) is the practice of structuring content so a search system can extract it as the direct answer to a question. It predates generative AI: featured snippets, voice assistants and knowledge panels were the original answer engines. AI Overviews, AI Mode and chat assistants extend the same demand for passages that answer a question plainly, near the top, in a form that stands on its own when lifted from the page.
- AI search optimisation
- AI search optimisation is the work of making a source usable by AI-assisted search: systems that retrieve documents at answer time, compose a response with a language model, and attach citations to some of what they used. It differs from optimising for a ranked list because the unit is the retrieved passage and the outcome is being composed from and cited, not a position. What the platforms document is access and eligibility; how they select among eligible sources is largely undisclosed.
- ChatGPT SEO
- ChatGPT SEO is the work of making a business reachable and usable by ChatGPT when it searches the web to answer a question. OpenAI documents three agents: GPTBot gathers training data, OAI-SearchBot indexes sites for ChatGPT's search features, and ChatGPT-User fetches pages when a user asks. Sites that opt out of OAI-SearchBot are not shown in ChatGPT search answers. How ChatGPT ranks the sources it retrieves is not documented.
- Google AI Overviews
- Google AI Overviews are generative summaries shown at the top of some Google Search results, with links to supporting pages. Google states they are a core Search feature drawn from the normal Search index: a page must be indexed and eligible for a snippet to be a supporting link, there are no additional requirements, and no special markup is needed. AI Overviews are available in Australia, so they appear for Perth searches.
Why Perth is its own research environment
Each dimension is labelled by how well it is established. A hypothesis is a reason to measure something, not a claim that it changes what an AI system does.
| Dimension | Why it matters for observation | Status |
|---|---|---|
| Local intent | Perth prompts are often recommendation or comparison prompts with a place attached, which narrows the eligible sources before any other factor applies. | INFERRED |
| Australian source ecosystem | ABN Lookup, ASIC, state regulators, Australian directories, review platforms and Australian publishers are candidate sources. Which ones get cited for Perth prompts is a question for observation. | HYPOTHESIS |
| Local business entities | Whether a Perth business is identifiable and consistent across its site, Google Business Profile, directories and registries is a measurable property of that business. | DOCUMENTED |
| Local organic search | Google documents that AI Overviews and AI Mode draw on its index and core ranking systems, so Perth organic performance is an input to Google surfaces. | DOCUMENTED |
| National versus Perth prompts | The same question with and without "Perth" can return different brands and sources. The gap is part of the programme design. | HYPOTHESIS |
How observations are collected
Methodology v1.0, published 2026-09-09. Versioned, so every observation says which rules it was collected under.
- Fixed prompt sets. Prompts are written once per study and kept constant across rounds.
- Repeated runs. At least 3 runs per prompt per platform, because outputs vary between sessions.
- Date, time and platform. Every record carries when it was collected, on which surface, with which model label.
- Controlled sessions. A clean baseline account plus seeded personas, so personalisation shows up as divergence between profiles.
- Citations and brands. Cited URLs, cited domains, brands mentioned and brands recommended, with order preserved.
- Source classes. Each cited domain classified as owned, third-party, platform-owned, UGC, directory, publisher or brand source.
- Variance reported. Frequencies across runs are published; a single run is never presented as a result.
- No universal score. There is no GEO score here. Results are frequencies per prompt set, platform and period.
