Generative engine optimization (GEO) is the practice of getting your business mentioned, cited or recommended inside answers written by AI tools such as ChatGPT, Perplexity, Gemini and Google AI Mode. SEO aims to rank a page in a list of links. GEO aims to be one of the few sources an AI chooses to build its answer from, and to be described accurately when it does.
The two share most of their foundations. The difference lies in what counts as winning, which signals carry extra weight, and how you measure progress.
Where did the term GEO come from?
The term was popularised by a 2023 academic paper titled "GEO: Generative Engine Optimization", written by university and research-institute computer scientists. It studied how changes to web content affect whether generative search systems include that content in their answers.
Since then, marketers have stretched "GEO" to cover almost anything related to AI visibility. You will see it used interchangeably with AEO, "AI SEO" and "LLM optimisation". For a business owner, the useful definition is simple: GEO is everything you do so that AI-written answers about your field include you, correctly.
What actually changes when an AI writes the answer?
The searcher gets one composed response instead of ten options, so being included matters more than being ranked. Several practical shifts follow from that.
- One answer, a few sources. A results page shows many links; an AI answer typically cites a handful. There is no "position seven" to settle for.
- Synthesis across pages. The AI combines facts from several sources, so a single strong statement on your page can be used even if the rest of the page is not.
- Sub-questions behind the scenes. Tools such as Google AI Mode break a question into related searches (Google calls this query fan-out), so coverage of follow-up questions matters.
- Memory as well as search. When an assistant answers without searching, it relies on patterns in its training data. Your brand appears only if it was mentioned often and consistently across the web.
- Fewer clicks, warmer visitors. Some people get what they need from the answer. Those who click through tend to be further along in their decision.
Which SEO tasks still matter for GEO, and what changes?
Nearly every core SEO task still matters; GEO changes the emphasis and adds a few jobs. Use this table to see what to keep, adjust or add.
| SEO task | Still matters for GEO? | What changes |
|---|---|---|
| Technical crawlability and indexing | Yes, essential | Also check that AI crawlers such as OAI-SearchBot and PerplexityBot are not blocked by robots.txt or firewalls |
| Keyword research | Yes | Shift towards full questions and follow-ups, not just short phrases |
| On-page content | Yes | Put the answer first; make each section quotable on its own |
| Backlinks | Yes | Unlinked brand mentions on credible sites gain importance alongside links |
| Page speed and experience | Yes | Main content should be readable in the HTML without heavy scripts |
| Structured data | Yes | Use it to state facts about your business clearly; it is support, not a shortcut |
| Local listings and reviews | Yes | Consistency of facts across platforms matters more, because AI tools cross-check |
| Rank tracking | Partly | Add prompt testing across AI tools and AI referral tracking |
| Original research | Helpful | Becomes one of the strongest reasons to be cited at all |
If you have been doing SEO properly, you are already most of the way there. If you have not, our honest look at whether SEO is worth it for small businesses is a sensible starting point.
Which signals matter more in GEO than in classic SEO?
Facts that are specific, consistent and available from you first. AI tools are trying to give a correct answer, so they favour sources that make correctness easy.
Specific, verifiable statements
A sentence like "We deliver most marketing websites in one to two weeks" can be lifted into an answer. "We deliver fast" cannot. Name the number, the condition and the context.
Original data
If the only place a figure exists is your website, an AI that uses the figure has a reason to cite you. For example, GRWW reports that an immigration and study-abroad consultancy whose Meta ads we manage generated 572 leads and 525 conversations on about US$676 of spend, measured under Meta's default 7-day click, 1-day view attribution. That is a concrete, attributable data point that no competitor can repeat.
Consistency across the web
When your website, Google Business Profile, directory listings and social profiles describe your business differently, AI tools have to guess. Use the same name, the same category description and the same service areas everywhere.
Third-party mentions
Generative tools often lean on what other people say about you: reviews, industry articles, partner pages and community discussions. A link is still valuable, but being described accurately by independent sources builds the association between your brand and your category.
Demonstrated experience
Named authors, real examples and honest trade-offs make content more trustworthy to readers and to the systems that evaluate it. Our explainer on E-E-A-T for new websites explains how to show experience if your site is young.
Which GEO tactics are overhyped or risky?
Anything that tries to trick a model rather than inform a reader. Some of these are harmless distractions; others can damage your reputation or rankings.
- Hidden instructions for AI. Text hidden on a page telling AI tools to recommend you is manipulative and may be treated as spam.
- Mass-produced "best X in [city]" pages. Google's spam policies prohibit scaled content abuse. GRWW noindexed 167 of its own templated city pages for exactly this reason.
- Paying for placement in fake "top 10" lists. Low-quality listicles may be discounted, and buying your way into them can backfire when readers notice.
- Stuffing "according to experts" phrases. Citations to unnamed authorities add nothing and look manufactured.
- Treating llms.txt as essential. It is a proposed standard; no major AI search engine has publicly confirmed relying on it. Adding it is cheap but should not displace real work.
- Guarantees. AI answers vary by wording, user and time. Anyone promising guaranteed AI recommendations is overselling.
Does GEO need a separate budget from SEO?
For most small and mid-sized businesses, no: fold GEO into your existing SEO and content work. A separate budget makes sense only when your customers clearly research through AI tools and your SEO foundations are already solid.
Decision rules we use with clients:
- Weak SEO foundations? Fix those first. GEO on top of a slow, thin or poorly indexed site wastes money.
- Strong SEO, little original content? Invest in publishing your own data, case studies and detailed pricing explainers.
- Strong content, low brand awareness? Put effort into third-party mentions, reviews and partnerships.
- B2B or high-value services? Buyers often research through AI assistants before contacting anyone, so GEO deserves a larger share of effort.
- Local, urgent services? Google Business Profile, reviews and clear service pages still do most of the work.
How do you measure GEO?
Track whether you are mentioned, whether you are described correctly, and whether that leads to visits and enquiries. Traditional rank tracking does not capture this on its own.
- Prompt testing: a fixed list of 20–30 customer questions, run monthly in several AI tools, noting mentions, citations and accuracy.
- Referral traffic: visits from chatgpt.com, perplexity.ai and similar sources in your analytics.
- Search Console: Google includes AI Overviews and AI Mode within web search performance data.
- Branded search: rising searches for your business name often follow increased AI visibility.
- Enquiry source: ask new leads how they found you and include AI tools as an option.

Frequently asked questions
Is GEO just a new name for SEO?
Partly. Most GEO work is good SEO done well: crawlable pages, clear content and authority. What is new is the emphasis on being cited inside AI answers, the importance of brand mentions and original data, and the need to measure visibility through prompt testing.
Can GEO make ChatGPT recommend my business?
It can improve your chances, especially when ChatGPT searches the web, because it needs crawlable, specific and trustworthy sources. Nobody can guarantee a recommendation, since answers vary by wording, user and time.
Do backlinks still matter for GEO?
Yes. Links remain an important signal for search engines, and many AI tools rely on search indexes. GEO adds weight to brand mentions that may not be linked, so both are worth earning.
How quickly does GEO work?
Improvements to pages that are already indexed can show up in AI answers that use live search within weeks. Changing what a model knows from training takes much longer, because it depends on future model updates and mentions building up across the web.
Should I rewrite all my content for GEO?
No. Start with the five to ten pages that matter most commercially, such as services, pricing and comparisons. Rewrite them answer-first with specific facts, then measure before deciding how much more to change.
