GEO vs SEO: what actually changes
The honest answer: not much, technically — and the differences that matter are about emphasis, not replacement. GEO (generative engine optimisation) is a research term coined in a 2023 academic paper, GEO: Generative Engine Optimization, which studied how content might be made more visible in systems that synthesise answers from many sources at once (arXiv:2311.09735). SEO is the older, documented discipline of helping search engines find, understand and rank pages. Google's own guidance closes the gap from the other side: it describes its AI features — AI Overviews and AI Mode — as using Search fundamentals, with "no additional technical requirements" beyond being indexed and eligible for a snippet (Google Search Central). If your pages are sound for search, they are already structurally sound for AI answers. What changes is how carefully you write for synthesis: clear facts, quotable sentences and verifiable sources.
What stays exactly the same
The foundations are shared, and Google documents them once for both:
- Crawlability and indexation. Pages must be reachable by crawler, not blocked by robots.txt directives you did not intend, and indexable (SEO starter guide).
- Useful, people-first pages. Google's helpful-content guidance asks whether a page demonstrates first-hand knowledge, serves a genuine reader need and states its purpose plainly (creating helpful content).
- Text and structure. Machine-readable text, descriptive headings, crawlable links and accurate structured data that matches the visible page (SEO starter guide).
None of this is waived for AI features. Google states a page needs only to meet Google's guidance and be eligible to appear; there is no separate GEO file, markup or submission route (Google Search Central).
Where the emphasis genuinely shifts
Where the GEO research differs from classic SEO practice is in the reader it imagines: not a person scanning a list of links, but a system that reads several sources and composes one answer.
- Answerability. State the specific facts a buyer asks about — who you serve, what you do, how you work — in plain sentences near the top of the page, rather than scattering them across marketing prose.
- Sources and attribution. The GEO paper studied specific optimisation strategies in a benchmark of queries and sources, and reported that some methods improved visibility in its experimental setup (arXiv:2311.09735). Treat that as a research result, not a general performance promise: the paper also reports that effectiveness varied across domains and calls for domain-specific methods. Whatever the method, clear attribution helps a reader check the claim and gives a synthesis system a source to follow.
- Wider source consideration. Google describes its AI features using "query fan-out" — issuing multiple related searches and drawing on a broader set of sources than a single results page (Google Search Central).
Treat those as refinements of good writing, not a new technical stack.
The limits, stated plainly
The same paper that named GEO also documents its ceiling: given the black-box, fast-moving nature of generative engines, content creators have "little to no control over when and how their content is displayed" (arXiv:2311.09735). No one can guarantee that an AI tool will crawl your site, cite it, quote it accurately, or mention it at all — and the platforms change behaviour without notice. The experimental results in the paper also varied by strategy and domain, so no single tactic transfers reliably.
A practical checklist
A "same foundation, different observation" routine for a service business:
- Keep the SEO basics honestly done: crawlable pages, clear titles, one page per service, accurate structured data (SEO starter guide).
- Write answer-first pages: the reader's question answered in the first sentences, with specifics.
- Support claims with visible, checkable sources; keep business facts consistent across your site and public profiles.
- Observe rather than assume: record how AI tools currently describe your business, on a dated prompt set, and re-test after changes under the same conditions. A few observations are notes, not market-wide measurements.

Frequently asked questions
Do I need to build a second website or separate content for GEO?
No. Google states its AI features use the same Search fundamentals and index, with no additional technical requirements (Google Search Central). One well-built site serves both.
Is GEO just SEO rebranded?
Partly overlapping, but the research term points at a real difference in reader behaviour: synthesising systems combine several sources into one answer (arXiv:2311.09735). The sensible response — clear, sourced, answerable pages — is within SEO practice already.
Can a provider guarantee my business appears in AI answers?
No. The platforms decide what to display, and the GEO paper itself notes creators have little control over display (arXiv:2311.09735). Treat any guarantee as a warning sign.
Which should I do first?
Fix the shared foundations first — they carry both outcomes — then refine answers, structure and sources. Doing only the "GEO" refinements on a technically poor site helps neither reader.
