The phrase "ai seo" now sits in every second agency pitch deck, but it covers at least three different disciplines, and most Australian buyers cannot tell which one they are actually being sold. Google AI Overviews appear on a meaningful share of informational queries on google.com.au. Perplexity and ChatGPT Search are sending measurable referral traffic to AU sites for the first time in 2026. That is real. What is less real is the assumption that bolting "AI" onto an existing SEO retainer changes the work underneath. This guide separates the three meanings of AI SEO, explains what to actually do this quarter, and sets out the signals that distinguish agencies shipping this work from those merely blogging about it. For foundational context, start with our plain-English explainer on what SEO is.
The three things people mean by AI SEO
When an agency advertises AI SEO services, they usually mean one of three things, and the scope of work should tell you which.
- Answer Engine Optimisation (AEO): optimising pages to be surfaced and summarised by generative answer engines like ChatGPT, Perplexity, Claude, and Google's Gemini-powered AI Overviews.
- Generative Engine Optimisation (GEO): structuring facts, entities, and citations so large language models reference your brand inside their generated answers. Wikipedia's entry on GEO is a reasonable primer.
- AI-assisted SEO production: using AI tools to draft briefs, cluster keywords, summarise audits, and accelerate the work. This is still conventional search engine optimisation, just with faster production.
Most of what agencies package as "AI SEO services" is the third category. That is not a criticism, but buyers should know what they are paying for.
Why AEO matters now in Australia
Google's AI Overviews are live on google.com.au for most informational queries, and Google's own AI features documentation describes how ranking content is selected for generative responses. Perplexity has reported Australia as one of its faster-growing markets. ChatGPT Search citations drive lower volume than organic but higher intent, because users arrive pre-qualified by the answer. Bing remains a rounding error in AU search share, but Microsoft Copilot surfaces Bing's index inside Windows 11, which shifts that calculus for B2B audiences.
What AEO optimisation actually looks like
The practitioners shipping this work focus on four moves. First, declarative answers in the first 150 words of a page, because that is the passage most often extracted into an AI Overview. Second, structured data using Schema.org types like FAQPage, HowTo, and Product, which act as a fact feed for language models. Third, brand mentions in authoritative Australian publications, because LLMs weight source authority when deciding who to cite. Fourth, an llms.txt file, an emerging convention with low implementation cost and no downside.
GEO is a different animal
GEO is about being cited, not only being found. The deliverables differ: author bylines with verifiable credentials, original data rather than recycled US statistics, and explicit entity markup using sameAs and knowsAbout properties. Most Australian content does not do this yet, so the first-mover advantage is genuine. The distinction between traditional ranking work and generative citation work is worth understanding in depth, and we cover it in our SEO vs GEO comparison.
AI tools that actually help SEO work
For production, keyword clustering tools like Keyword Insights and SurferSEO genuinely compress weeks of analysis. Brief generation with Frase, MarketMuse, or direct prompting of Claude or ChatGPT works if a human strategist reviews the output. Screaming Frog combined with AI triage speeds up technical audits. What AI cannot reliably do: replace editorial judgment, generate Australian-voice content at scale without heavy editing, or audit a backlink profile for quality.
The Australian regulatory context
Three frameworks matter. The ACCC has issued guidance on AI-generated content and deceptive claims under Australian Consumer Law, which applies to any AI-written review or testimonial. The Office of the Australian Information Commissioner enforces the Privacy Act 1988, and any AI tool that sends customer data offshore for processing needs a privacy impact assessment. Regulated industries such as legal and financial services already face disclosure obligations when AI is used in client-facing material.
Who actually delivers AI SEO in Australia
Most AU agencies discuss AI in blog posts. Fewer ship it as a distinct service. Signals that a firm genuinely practises this work: AEO case studies with citation screenshots, GEO-specific deliverables written into the scope of work, and original AU data rather than translated US research. Marketing-voiced pages with no evidence should be treated with the scepticism they deserve.
What to do this quarter
- Audit your top 20 pages for AI Overview eligibility, specifically whether a clear answer appears in the first 150 words and whether FAQ schema is present.
- Publish an llms.txt file.
- Secure one citation from an Australian publication to strengthen brand authority signals.
- Review your AI-production tool stack for privacy and ACCC compliance, particularly where customer data is involved. For geography-anchored work, pair this with a local SEO review.
When to hire an AI SEO specialist
Three signals justify a specialist engagement: competitors appearing in AI Overviews while you do not, a planned GEO-driven content push, or regulatory exposure that requires an informed provider. If those apply, browse the directory of AI-capable agencies filtered to AEO and GEO capability.
FAQ
What is AI SEO?
It covers AEO (optimising for ChatGPT, Perplexity, and AI Overviews), GEO (being cited inside generated answers), and AI-assisted SEO production (using AI tools to accelerate conventional SEO work).
Will AI replace SEO?
No. It changes what ranks and where the traffic lands, not the underlying discipline of matching content to intent.
How do I rank in AI Overviews?
Clear declarative answers early on the page, FAQ schema, and brand authority built through citations in Australian publications. Coverage in the industry trade press remains the clearest signal.
Should I use llms.txt?
Yes. Low cost, emerging standard, no downside.
