FIRST: WHAT IS SEO?
SEO — search engine optimisation — is the practice of improving how easily a website can be discovered, understood and ranked by search engines. It covers the technical foundations (can the site be crawled and indexed?), the content (does it answer the query and demonstrate authority?), and the signals around it (links, mentions, consistency, trust).
The objective is visibility in search results for the queries that matter to a business, and the work is well established even as the details keep moving.
WHAT IS GEO?
GEO — Generative Engine Optimisation — is a newer term used to describe optimising for generative, AI-powered search experiences: the kind that produce a synthesised answer rather than a list of links.
The distinction people are reaching for is real: an AI summarising an answer is doing something different from a search engine ranking ten pages. But the terminology is still developing, and it is worth being honest about that. There is no single, universally agreed technical standard for what "GEO" means yet, and the term is used differently by different people.
A useful working definition: GEO is the practice of improving the likelihood that your information is clear, useful and attributable when an AI system is choosing what to surface, summarise or cite. It is the optimisation of extractability and attribution, more than ranking.
If you want the broader frame, what is AI SEO? covers how the whole landscape fits together.
SEO VS GEO AT A GLANCE
This is a comparison of emphasis, not of absolutes. Most rows are "greater emphasis" rather than "only matters to one side."
| Dimension | SEO | GEO | | --- | --- | --- | | Primary environment | Traditional search results (the "ten blue links" and their modern variants) | Generative / AI-powered answer experiences | | Discovery | Ranked results for a query | Synthesised answers that may summarise, cite or omit sources | | Crawlability | Foundational — the site must be readable | Foundational — the underlying information must be accessible to the system | | Content | Must be relevant, useful and authoritative | Must additionally be clear, extractable and easy to summarise | | Keywords / intent | Central to matching and ranking | Still relevant, but understood more broadly as context and intent | | Entities | Important for understanding and disambiguation | Greater emphasis on clear entity identification and relationships | | Links / authority | A core ranking signal | Corroboration and authority still matter for what gets surfaced and trusted | | Structured data | Helps machines understand content and relationships | Greater emphasis — explicit entities and attribution are useful to generative systems | | Attribution / citation | Implicit (the result links to the source) | Greater emphasis — whether the source is named and credited in the answer | | Measurement | Rankings, organic traffic, impressions, conversions | Less settled — referral from AI surfaces, mentions, citations; harder to attribute cleanly |
The pattern: GEO is not a different sport. It is SEO plus a sharper focus on clarity, extractability and attribution — because those are the things a generative system depends on.
WHAT SEO AND GEO HAVE IN COMMON
This is the part that gets missed in the "SEO is dead" framing. The two share far more than they differ:
- Technical accessibility — both need a readable, crawlable, well-structured site.
- High-quality content — both reward genuinely useful, well-written information.
- Authority — both care about whether the source is credible and corroborated.
- Clear structure — both benefit from logical headings, hierarchy and scannability.
- Brand and entity signals — both want it to be obvious who the business is and what it is about.
- External references — both value mentions, links and consistency across the web.
- User intent — both fail when the content doesn't actually answer the question.
If you are doing good SEO, you are already doing a lot of good GEO. The overlap is the point.
DOES GEO REPLACE SEO?
No.
This is the strongest thing I can say with confidence, and it is worth saying plainly because the opposite gets repeated a lot.
SEO is not disappearing. The interface is changing. People are increasingly getting some answers directly from AI-generated summaries instead of clicking through ten results — but those summaries are built on crawled, indexed, authoritative information. The work that produces that information is still SEO, and it still matters.
A better mental model: the surface where discovery happens is widening, and some of it is generative. The foundations underneath are the same foundations they have always been. Get those right, and you are in a good position across both.
The risk isn't that SEO is dying. The risk is assuming the old surface is the only surface, and ignoring how people now actually discover businesses.
WHAT SHOULD BUSINESSES ACTUALLY DO?
A practical priority, in order:
- Get technical SEO right. Crawlability, indexability, architecture, performance, clean structured data. This is non-negotiable for both.
- Make entities clear. Who you are, what you do, what you're authoritative about — stated consistently on the site and across the web.
- Build genuinely useful topical content. Not content for content's sake — coverage that actually answers the questions your customers ask.
- Strengthen authority. Real expertise, real references, real corroboration. Not link schemes.
- Structure information clearly. Headings, hierarchy, plain answers, extractable passages.
- Monitor how search behaviour evolves. Watch where your traffic and mentions come from, including emerging AI surfaces, and adjust.
Notice that none of that says "abandon SEO and do GEO instead." It says: do SEO well, and sharpen the bits that generative search depends on most.
SEO, GEO OR AI SEO — WHAT SHOULD WE CALL IT?
This is the question that matters least, and it is worth saying so.
The labels are still settling. Different people use "AI SEO," "GEO" and "generative search optimisation" to mean overlapping things, and the terminology will keep moving. What matters is the objective underneath all of them:
Help machines and people understand why you're relevant.
That is it. Whether you call the work SEO, GEO or AI SEO, the job is to make your business discoverable, understandable and trustworthy — across the surfaces where discovery now happens.
If it helps to put a frame around it: what is AI SEO? is the broader term, and entity SEO is one of the most useful things within it. Read those, and the terminology starts to matter a lot less than the work.
