SEO helps buyers find your pages in search results. AEO helps answer engines extract a direct response from them. GEO helps generative engines understand, cite and recommend your brand. That is the short answer to AEO vs GEO vs SEO.
For an Australian SaaS founder, they are layers, not rival channels. If your site is not accessible, relevant and credible enough to rank, FAQ schema or an llms.txt file will not rescue it. Your first dollar normally belongs in SEO foundations. AEO and GEO should then shape how you create and measure content. The exception is a known product in a category buyers research heavily through ChatGPT or Perplexity.
AEO vs GEO vs SEO at a Glance
| Layer | Primary goal | Where visibility appears | Typical work | Best early measure |
|---|---|---|---|---|
| SEO | Earn discoverability and clicks | Google and Bing results | Technical SEO, keyword research, content, internal links and authority | Qualified impressions, rankings and organic pipeline |
| AEO | Become the extracted answer | Featured snippets, People Also Ask, voice and direct answers | Clear definitions, question-led sections, concise answers and valid schema | Answer ownership and assisted conversions |
| GEO | Be included or cited in a generated response | Google AI features, ChatGPT, Perplexity and Copilot | Entity clarity, original evidence, third-party mentions and citation-ready content | Citation share, brand mentions and referral traffic |
One comparison page can rank through SEO, supply a featured snippet through AEO and earn an LLM citation through GEO. Google says its generative AI features rely on core ranking and quality systems, so SEO best practices remain relevant to AI search.
GEO vs SEO: What Is the Difference?
The central difference in GEO vs SEO is the output. SEO aims to rank a webpage. Generative engine optimisation makes business information retrievable, trusted and useful enough for a synthesised answer.
With SEO, a buyer might search “best payroll software Australia”, review blue links and visit vendors. With GEO, the buyer may ask, “Which payroll platform suits a 40-person Australian startup using Xero?” The engine synthesises multiple sources and may mention only a few brands.
This changes the unit of competition:
- SEO competes for a ranking and click.
- GEO competes for inclusion, accurate representation and citation.
- SEO typically starts with a query; GEO also considers longer prompts and follow-up questions.
But a generative engine still needs material to retrieve. Crawlable product pages, a clear company entity, useful comparisons, customer evidence and independent coverage help both systems understand your product.
The original Generative Engine Optimization research found that optimisation methods could improve source visibility by up to 40%, with results varying by topic. That shows presentation matters; it does not promise 40% more pipeline.
What Is GEO in SEO?
GEO improves how a brand and its information appear in AI-generated answers. It extends the goal from “rank this URL” to “make this claim easy to retrieve, verify and cite”.
Useful GEO work includes original data, consistent product facts, relevant third-party mentions, comparison content and claims traceable to primary sources. Repeating “best AI platform” is not GEO; it is an unsupported claim.
AEO vs SEO: What Changes?
Answer engine optimisation vs SEO is mostly a difference in format and immediate objective. SEO earns the chance to be found. AEO increases the chance that the page supplies the answer directly.
If a founder asks, “How much does AEO cost in Australia?”, an answer-ready page gives a qualified range immediately, explains what changes the cost and then supplies decision detail.
Strong AEO content usually has:
- a direct answer immediately below the relevant heading;
- descriptive questions that match the buyer’s language;
- short definitions followed by evidence and nuance;
- tables for exact comparisons;
- consistent entities, dates and sources;
- structured data that describes visible content.
Structured data can help Google understand a page but does not guarantee a rich result. FAQ schema is a labelling tool, not a ranking lever.
What Is AEO in SEO?
AEO stands for answer engine optimisation. It helps search engines, voice assistants and AI systems identify a reliable answer with minimal ambiguity. An engine normally must discover, crawl and trust the page before extracting it.
The practical AEO vs SEO distinction is simple: SEO asks, “Can the right buyer find this page?” AEO asks, “Can the engine and buyer identify the answer in seconds?”
AEO vs GEO: Which AI Search Layer Matters More?
In AEO vs GEO, AEO focuses on the answer itself; GEO focuses on your visibility within a generated synthesis. AEO is often page-level. GEO is broader and more entity-level.
An AEO project might rewrite a pricing guide so the cost answer is explicit and qualified. A GEO project also aligns your pricing, positioning and customer profile across your site, directories, reviews and independent coverage, giving an engine corroborating sources.
Prioritise AEO when buyers ask stable, factual questions that your site can answer definitively. Prioritise GEO when buyers ask comparative or recommendation prompts and engines need evidence from beyond your own website.
Most SaaS companies need both behaviours in one asset: answer the question clearly, then support the conclusion with product evidence, transparent methodology and credible sources.
Is GEO Replacing SEO?
No. GEO is changing what successful search visibility includes, but it is not replacing SEO.
Google requires a page to be indexed and eligible to show a snippet before it can appear in its AI features. Its official guidance also says there is no special AI markup required. In particular, Google says it does not use llms.txt for its Search or generative AI features.
Other AI platforms may behave differently, but Aussie SaaS teams should distrust “AI SEO hacks” that bypass crawlability, useful content or authority.
Think of the relationship this way:
- SEO creates the discoverable evidence base.
- AEO makes individual answers clear and extractable.
- GEO connects those answers to a recognisable, corroborated entity.
Remove the first layer and the other two become fragile.
Where Should an Aussie SaaS Spend First?
Most early-stage SaaS companies should fund SEO foundations first while applying AEO structure and GEO evidence standards from day one. Do not split a small budget across three overlapping retainers.
Use these four questions to choose the highest-leverage next dollar.
1. Can Search Engines Reliably Find and Understand the Site?
If pages are not indexed, internal links are weak or positioning is vague, start with SEO. Fix measurement, technical blockers, architecture and the commercial pages closest to revenue.
Indicative first spend: A$3,000-A$8,000 for a focused foundation project, depending on site complexity. This is a planning range, not a market-wide benchmark.
2. Does Existing Content Rank but Fail to Win Answers?
If pages rank but rarely capture snippets, AI summaries or conversions, add AEO. Rewrite openings, answer real questions, clarify definitions and apply accurate schema.
Indicative allocation: 20-30% of the content budget to refreshing pages close to winning.
3. Are Buyers Asking AI Engines for Recommendations?
Test the prompts prospects use during consideration: “best”, “versus”, “alternative”, “for a team like mine” and “integrates with”. If your brand is absent or described inaccurately across repeated tests, invest in GEO.
Start with a prompt and citation audit. Close evidence gaps through original research, comparisons, use cases, review profiles and relevant digital PR. Do not manufacture mentions.
4. Is There Enough Demand to Justify the Work?
A category-creation startup may have little keyword volume even though prospects ask AI tools about the problem. Bring GEO research forward there. In an established category with high-intent searches, build SEO coverage first. Buyer behaviour matters more than acronym popularity.
A Stage-Based Budget Framework
| SaaS situation | Spend first | Why | Next layer |
|---|---|---|---|
| Pre-PMF or unclear positioning | Customer research and core SEO pages | Search optimisation cannot repair an unclear offer | AEO once questions repeat |
| New site in an established category | Technical and commercial SEO | You need discoverability and demand capture | AEO during every content brief |
| Ranking site with weak CTR or conversions | AEO-led content refreshes | Existing visibility can produce faster gains | GEO for comparison prompts |
| Recognised brand missing from AI answers | GEO audit and authority building | The gap is likely corroboration or retrievability | Continue SEO maintenance |
| Enterprise SaaS with a complex buying committee | Integrated SEO, AEO and GEO | Buyers research across many sources | Measure pipeline by topic |
With A$6,000, a lean startup might put A$4,000 into technical and commercial fixes, A$1,500 into one answer-ready cluster and A$500 into AI visibility testing.
A Practical 90-Day Plan
Days 1-30: Build the baseline. Audit indexing, analytics, conversion paths and commercial coverage. Record 20-30 buyer prompts across Google, ChatGPT, Perplexity and Copilot. Track brand appearances, citations and recurring competitors.
Days 31-60: Improve the evidence. Fix technical blockers and refresh pages nearest revenue. Answer important questions directly, then add product evidence, methodology, examples, limitations, dates and primary sources.
Days 61-90: Build corroboration. Publish one citeable asset, such as Australian benchmarks or anonymised product data. Earn relevant coverage, re-run the prompt set and compare citation share and accuracy.
Measure qualified organic pipeline, non-brand visibility, conversions, AI referrals, brand inclusion and citation accuracy. One ChatGPT appearance is not a KPI.
How Much Does AEO Cost?
AEO can cost a few thousand Australian dollars for a focused audit and refresh or reach five figures monthly with research, production, technical work and measurement. Scope matters more than the label.
A credible proposal identifies priority queries, pages, answer formats, technical changes and measurement. If “AEO” only adds FAQs and schema, or renames existing SEO work, challenge the budget.
The Verdict: Fund the Foundation, Optimise the Whole System
The honest answer is not three equal budget lines. For most Aussie SaaS businesses, SEO earns the first investment because it builds the access, content and authority other engines also need.
Use AEO to make answers unmistakable and GEO to make claims consistent, verifiable and citeable. Already ranking but absent from AI recommendations? Fund GEO next. Visible but rambling? Prioritise AEO. Still undiscoverable? Stay with SEO.
Follow the buyer, not the acronym. Book a search visibility audit to identify the layer limiting qualified pipeline.
FAQs
What Is the Difference Between SEO, GEO and AEO?+–
SEO targets ranked results, AEO makes direct answers extractable, and GEO targets inclusion and citations in AI-generated responses. They work as layers of one strategy.
What Does AEO Stand for in Marketing?+–
AEO means answer engine optimisation: creating clear, supported responses for search engines, voice assistants and AI interfaces.
Should a SaaS Startup Do GEO or SEO First?+–
Most SaaS startups should establish SEO first and apply GEO principles while creating content. Prioritise GEO when buyers use AI for comparisons and your brand is absent or misrepresented.
How Do I Optimise Content for AI Search?+–
Make pages crawlable, answer directly, use clear headings, support claims with primary evidence, keep product facts consistent and earn legitimate coverage. Track citations and qualified traffic, not llms.txt.
