SEO vs AEO vs GEO: what's the difference?
SEO gets a page ranked, AEO gets a passage chosen as the direct answer, and GEO gets your facts cited by AI engines. They share the same foundations — crawlable, accurate, well-structured content — and differ in what they optimise and how you measure success.
Three acronyms, a great deal of marketing noise, and one genuinely useful distinction underneath: they optimise different units and are judged by different outcomes.
The practical news is good. They are not three competing strategies requiring three budgets. They are layers on the same foundation, and doing the first well gets you most of the way to the other two.
The one-line difference
SEO ranks a page in a list of results. AEO gets a specific passage chosen as the direct answer shown above or instead of that list. GEO gets your facts retrieved, quoted and attributed inside an AI-generated answer.
Or, put in terms of what success looks like: SEO wins a position, AEO wins the answer box, GEO wins the citation.
- SEO — unit: the page. Outcome: a ranking. Measured in Search Console.
- AEO — unit: a passage. Outcome: a featured snippet, 'People also ask' entry or voice answer. Partially measurable.
- GEO — unit: a fact. Outcome: being cited in a generated answer. Barely measurable.
What each one adds on top
The specific work that belongs to each layer, once the foundation is in place.
- SEO adds: keyword and intent research, title and meta optimisation, internal linking architecture, technical health, and earned links and authority.
- AEO adds: answer-first writing, question-shaped headings taken from real queries, 40–60 word self-contained answers, format matching (list for 'how to', table for comparisons), and FAQPage or HowTo markup.
- GEO adds: specific dated figures with named primary sources, explicit authorship and review dates, honest statements of uncertainty, entity disambiguation via Organization and sameAs markup, and deliberate AI-crawler permissions.
Where they genuinely conflict
Mostly they reinforce each other, but there are two real tensions worth naming.
The first is the zero-click tension. Optimising hard for AEO and GEO means more users get their answer without visiting you. The resolution is to win the answer for the narrow question while making the page obviously worth opening for the fuller one — a calculator, a table of every case, the exceptions, the local specifics.
The second is length. Classic SEO advice pushes towards comprehensive long pages; extraction favours short self-contained blocks. These are reconcilable — a long page built from short, clearly-labelled, self-contained sections satisfies both — but a long page of unbroken prose satisfies neither.
How to do all three at once
A single workflow that covers all three layers, in order.
- Pick one intent per page and confirm the format that already wins for it.
- Open with a two-to-three sentence summary that answers the whole question — this serves AEO and GEO simultaneously.
- Use question-shaped H2s taken from 'People also ask', with a self-contained answer directly beneath each.
- State specific figures with units, and give the date you verified them.
- Cite primary sources by name and link them.
- Add Article, FAQPage or HowTo and BreadcrumbList markup reflecting what is visible.
- Add a key-takeaways block: highly quotable, and genuinely useful to readers.
- Make it fast on mobile, link it internally, and check your robots rules allow both search and AI crawlers.
Which to prioritise
If you are starting from nothing, do them in order — SEO, then AEO, then GEO — because each depends on the previous one. There is no point optimising for AI citation on a page that is not indexed.
If you have an established site, the highest-return work is usually AEO retrofitting: taking pages that already rank on page one and restructuring them into answer-first, question-headed blocks. The traffic already exists; you are converting rankings into answers.
GEO is worth doing now on the pages where being the cited authority matters — reference facts, figures, procedures — because the practices cost little and the discipline is still young enough that specificity and sourcing genuinely differentiate you.
Key takeaways
- ✓SEO wins a position, AEO wins the answer box, GEO wins the citation.
- ✓They are layers on one foundation, not three competing strategies — crawlability, intent, accuracy and structure serve all three.
- ✓AEO adds answer-first passages and question-shaped headings; GEO adds dated figures, named sources and crawler permissions.
- ✓The real tension is zero-click: win the narrow answer, and make the page worth opening for the full one.
- ✓On an established site, retrofitting AEO onto pages that already rank is usually the highest-return work.

SEO vs AEO vs GEO — FAQ
What is the difference between SEO, AEO and GEO?+
SEO ranks a page in the results list. AEO gets a specific passage chosen as the direct answer in a featured snippet, 'People also ask' or a voice result. GEO gets your facts retrieved, quoted and attributed inside an AI-generated answer. They optimise different units — page, passage and fact.
Do I need to do all three?+
They are layers on the same foundation rather than three separate budgets. Get crawlability, intent-matching, accuracy and structure right and you have most of all three. Then add answer-first writing for AEO and dated, sourced specifics for GEO.
Which should I focus on first?+
SEO first, because AEO and GEO both depend on being indexed and retrievable. On an established site, the highest-return work is usually retrofitting AEO onto pages that already rank on page one — the traffic exists and you are converting rankings into answers.
Does AEO and GEO reduce my website traffic?+
They can, for narrow factual queries answered fully in the result. The mitigation is to win the answer for the narrow question and make the page obviously worth opening for the fuller one — the calculator, the full table, the exceptions, the local detail.
Is GEO just a rebrand of SEO?+
Partly, and it is right to be sceptical of the marketing. The fundamentals are the same, but the emphasis genuinely shifts: generative engines penalise vagueness far more heavily, because they need facts they can assert safely, and AI crawler permissions are a real, separate technical control.
