Three acronyms, one underlying shift: search results increasingly answer the question directly instead of just linking to a page that might. GEO, SEO, and AEO all describe some part of adapting to that shift, and the terms get used inconsistently enough that it’s worth a straight, side-by-side explanation.
The Short Version
| Term | Full name | Focuses on |
|---|---|---|
| SEO | Search Engine Optimisation | Ranking visibility across search generally — the umbrella term and the foundation the other two build on |
| AEO | Answer Engine Optimisation | Being extracted and cited as a direct answer, particularly in Google’s AI Overviews and AI Mode |
| GEO | Generative Engine Optimisation | Visibility specifically within generative AI chat tools — ChatGPT, Perplexity, Gemini’s conversational mode |
None of these replace each other. SEO is the base layer every site still needs. AEO and GEO are more specific lenses on the same underlying problem — how do you get found and cited when the “search result” is a generated answer rather than a list of links — applied to slightly different surfaces.
Where the Terms Genuinely Overlap
In practice, the tactics that improve AEO and GEO performance are close to identical, and both build directly on solid SEO fundamentals:
- Clear, answer-first content structure
- Explicit, well-defined terminology an AI system can extract confidently
- Structured data and schema markup
- Genuine topical authority and trustworthy sourcing
- Clean technical crawlability, so content can actually be accessed and parsed
If you’re optimising well for one, you’re largely optimising for the others at the same time. The distinction is more useful for precise industry conversation — knowing which surface a client or colleague means — than for building two separate content strategies.
Where They Genuinely Diverge
The practical difference shows up in a handful of places:
- Citation behaviour differs by platform. Google’s AI Overviews tend to cite sources more consistently than some generative AI chat tools, which sometimes synthesise an answer without a visible citation at all. Optimising for GEO specifically means accepting that citation — and therefore traceable traffic — is less guaranteed on some platforms than others.
- Query style differs. Generative AI chat tools tend to receive longer, more conversational queries than a traditional Google search box. Content written to match that conversational phrasing performs differently across the two surfaces.
- Measurement differs. Traditional SEO has mature tooling (Search Console, rank trackers). AEO and GEO performance is still measured more informally — manually testing target queries across platforms, or estimating from referral traffic patterns — since no single reporting standard has emerged across every AI platform yet.
Which Term Should You Actually Use?
For most businesses, this is a non-issue — “AI SEO” or “AI search optimisation” communicates the intent clearly enough in general conversation, and the underlying work is largely the same regardless of which acronym gets used. The distinction matters more if you’re briefing a specialist, reading a technical guide, or trying to understand exactly which platform a piece of advice applies to. In that context, treat SEO as the foundation, and AEO/GEO as more precise descriptions of where that foundation is being specifically applied.
Frequently Asked Questions
Is GEO replacing SEO?
No. GEO describes optimising for generative AI chat tools specifically, and it depends entirely on the SEO fundamentals — content quality, authority, technical crawlability — already being solid.
Do I need a separate strategy for AEO, GEO, and traditional SEO?
Generally no. The core tactics overlap heavily enough that one well-executed content and technical strategy serves all three, with only minor platform-specific adjustments where needed.
Which is more important for a small Australian business — AEO or GEO?
Usually AEO, since Google’s AI Overviews currently reach a far larger share of everyday search traffic in Australia than dedicated generative AI chat tools. That balance may shift as AI chat tools grow, but it’s the more urgent priority for most businesses right now.
How do I measure GEO or AEO performance?
There’s no single standardised reporting tool across every AI platform yet. Most practical measurement involves manually testing target queries across the major platforms and watching for referral traffic that suggests AI-driven citation.
Will these terms still be used in a year?
Possibly not in their current form — this is genuinely new, still-settling terminology. What’s unlikely to change is the underlying shift toward answer-based search, so the practical work described under these labels is a safe investment even if the acronyms themselves evolve.
