Somewhere in the past year, someone has probably told you that SEO is finished and GEO is what you need now. It may have arrived with a new proposal, a new tool subscription or a second agency. The pitch sounds urgent. It also leaves a practical question that rarely gets a clear answer: what should you actually do differently?
This guide answers that question with primary sources instead of opinions. We read Google’s own guide to generative AI features in Search (last updated in July 2026), the research paper that introduced the term GEO and OpenAI’s crawler documentation. Then we compared them with what we see when we run SEO and AI search programmes for premium brands at Viralistic. The short version: most of what wins in AI answers is good SEO. The rest is worth knowing precisely.
What is the difference between SEO and GEO?
SEO (search engine optimisation) makes your pages easy to find, understand and trust, so they rank in Google and Bing and earn the click. GEO (generative engine optimisation) makes your content easy to retrieve and quote, so AI systems use it, and ideally cite it, when they write an answer. SEO competes for a position in a list of results. GEO competes for a place inside one generated answer.
The term comes from a 2023 research paper, GEO: Generative Engine Optimization, by Pranjal Aggarwal and five co-authors, later accepted at the KDD 2024 conference. The authors defined generative engines as search systems that gather and summarise information with large language models, and they introduced GEO as “the first novel paradigm to aid content creators in improving their content visibility in generative engine responses”.
| SEO | GEO | |
|---|---|---|
| Where you appear | Organic results in Google and Bing | Google AI Overviews and AI Mode, ChatGPT search, Perplexity, Microsoft Copilot |
| What success looks like | A ranking and a click | A mention or a linked citation inside the answer |
| What people ask | Search queries, often short | Nuanced questions that used to take several searches, plus follow-ups |
| How sources are chosen | Ranking systems order whole pages | The system retrieves pages from an index, then grounds its answer in specific passages |
| Main levers | Crawlability, relevance, helpful content, links | The same, plus well-sourced, quotable passages and consistent facts across the web |
| Where you measure it | Search Console Performance report, rank tracking | Search Console Generative AI performance report, Bing AI Performance, referral traffic |
Where AEO fits in
AEO (answer engine optimisation) is the broader label for being chosen as the direct answer, whether that answer appears in a featured snippet, a voice assistant or an AI reply. GEO is the part of it that deals with answers a language model writes itself. The advice overlaps almost completely, and Google’s guidance names both terms in the same sentence when it explains which popular hacks you can skip.
What does Google say about GEO?
For Google Search, GEO is SEO. Google’s guide Optimizing your website for generative AI features on Google Search asks directly whether SEO is still relevant for generative AI search, and the answer is an unqualified yes. The reason is structural. Google’s AI features “are rooted in our core Search ranking and quality systems.”
Two mechanisms explain how that works. The first is retrieval-augmented generation, which Google also calls grounding: the AI feature uses Google’s core ranking systems to retrieve relevant pages from the Search index, writes a response based on them and links to the pages that support it. The second is query fan-out: the model runs several related searches at the same time to cover subtopics. Google’s own example is a question about fixing a lawn full of weeds, which fans out into searches such as “best herbicides for lawns” and “how to prevent weeds in lawn”.
The technical bar is the same as well. Google’s page on AI features and your website says a page must be indexed and eligible to appear in Search with a snippet to be shown as a supporting link in AI Overviews or AI Mode, and that “there are no additional technical requirements.”
There is one new switch. Since 31 August 2026, every site has a Search generative AI control in Search Console, which lets you include or exclude your content from AI Overviews, AI Mode and generative features in Discover. Inclusion is the default, so there is nothing to opt in to.
The GEO tactics Google says you can ignore
Google’s guide has a section called “Mythbusting generative AI search”. For Google Search, it lists these as things you do not need to do:
- Chunking content into tiny pieces. Google’s systems understand pages that cover several topics, and “there’s no ideal page length.”
- Rewriting content just for AI. AI systems understand synonyms and meaning, so you do not need every long-tail variation of a phrase.
- Seeking inauthentic mentions. Generative features depend on the same quality and spam systems as the rest of Search.
- Overfocusing on structured data. It is not required and “there’s no special schema.org markup you need to add”, although it still helps with rich results.
- Creating AI text files such as llms.txt. Google lists them among the tactics you can ignore.
Google also warns against publishing a separate page for every fan-out question. Doing that mainly to manipulate rankings or AI responses violates its scaled content abuse policy.
One nuance is worth keeping. These statements are about Google Search. Other assistants make their own choices, which is why we treat an llms.txt file as an optional ten-minute extra on the sites we build, never as a strategy. Our help article on getting cited by AI search shows how we set that up.
SEO vs GEO: where they genuinely differ
The foundation is shared, but a few things really do change: what counts as success, which engines you deal with, what kind of content gets quoted and how you measure it.
A citation is not a click
In classic search, visibility and traffic travel together. In an AI answer, your brand can shape the response, be named or be linked as a source while the reader never visits your site. Being cited correctly becomes a brand question as much as a traffic question. It also changes the value of the clicks you do get. Google reports that when people click through from results pages with AI Overviews, “these clicks are higher quality (meaning, users are more likely to spend more time on the site).”
More than one engine, with its own crawlers
For most businesses, SEO has meant Google first. GEO means several systems, each with its own crawler and rules. OpenAI’s crawler documentation separates OAI-SearchBot, which surfaces websites in ChatGPT search, from GPTBot, which crawls content for model training. Sites that block OAI-SearchBot “will not be shown in ChatGPT search answers”, although they can still appear as navigational links. Blocking GPTBot does not take you out of ChatGPT search. Check which of the two your robots.txt blocks, because they do different jobs.
Rendering is one of the few real technical gaps. Googlebot renders JavaScript, and Google’s Gemini uses the same infrastructure. A December 2024 study by Vercel and MERJ found that none of the major AI crawlers rendered JavaScript at the time, including OAI-SearchBot, ClaudeBot and PerplexityBot. Text that only appears after JavaScript runs can be invisible to them, and so can links that are not real HTML anchors (our guide to a href SEO covers that side). Static or server-rendered HTML removes the risk.
Evidence gets quoted, keywords do not
The GEO paper tested nine ways of rewriting web content on GEO-bench, a benchmark of 10,000 queries. The three best performers were adding citations from reliable sources, adding credible quotations and adding relevant statistics, with a relative improvement of 30 to 40 percent on the authors’ main visibility metric. Keyword stuffing, the old SEO reflex, offered “little to no improvement”, and in a test on Perplexity it performed 10 percent worse than leaving the content untouched.
A second finding matters even more for most businesses. The gains were largest for sources that started lower. Adding citations raised the visibility of the website ranked fifth in the underlying search results by 115 percent, while the top-ranked website lost 30 percent. In a generative answer, the best evidence can beat the strongest position. For a smaller brand with real expertise, that is an opening.
Treat these numbers as direction, not as a guarantee. The tests ran in 2023 on a research engine built on GPT-3.5 Turbo and on Perplexity. They do line up with Google’s own advice to publish non-commodity content with “unique expert or experienced takes”.
New reports to measure AI visibility
Measurement is where GEO is genuinely new. Google Search Console now has a Generative AI performance report, rolled out to all websites by 31 August 2026, which shows impressions in AI Overviews and AI Mode by page, country and device. Bing Webmaster Tools added an AI Performance report in public preview in February 2026, with citation counts across Microsoft Copilot and Bing’s AI summaries and sample “grounding queries”. For ChatGPT and Perplexity, look at referral traffic in your analytics and regularly ask them the questions your buyers ask. Tools such as Ahrefs Brand Radar track how often AI assistants mention a brand; our guide to Ahrefs explains what the platform does and costs.
Is GEO replacing SEO?
No. GEO is a layer on top of SEO, not a replacement for it. Google’s AI features retrieve pages from the same index through the same ranking systems, and ChatGPT search depends on its own crawler being allowed to fetch your site. If a page is not crawlable, indexed and trusted, no GEO tactic will put it in an answer.
What has changed is the bar for content. A page that restates what ten other pages already say adds nothing to an AI answer, because the model has seen that common knowledge many times over. Google’s guide puts it plainly: “Don’t just recycle what others on the internet have already said, or could easily be produced by a generative AI model.” The pages that get used bring something of their own: first-hand experience, original data or a clear point of view.
How to optimise for SEO and GEO at the same time
One programme covers both. In order of impact:
- Make every important page findable. Check that robots.txt, your CDN and your hosting allow Googlebot, Bingbot and OAI-SearchBot, that the pages are indexed and that internal links are real HTML links.
- Put the content in the HTML. Important information should exist as text without JavaScript, with images and video supporting it rather than replacing it. Our guide to SEO for software companies shows why single-page marketing sites are most at risk.
- Write what only you can write. Use experience from your own projects, your own numbers and your own view. Google calls this non-commodity content, and it is exactly what generative answers need from you.
- Back up your claims. Cite primary sources, quote real experts by name and add statistics you can verify. These were the strongest tactics in the GEO research.
- Answer first, for people. Open each section with the direct answer, then add the detail. Do it because readers scan, not to chunk content for machines.
- Keep your facts consistent. Your website, Google Business Profile, Merchant Center feed and profiles elsewhere should describe the same company, services and prices. Google’s guidance names Business Profile and Merchant Center specifically.
- Earn real mentions. Press, partners, events and reviews carry weight. Bought or fabricated mentions do not.
- Measure both surfaces. Track rankings and clicks next to AI impressions and citations, and judge all of it on qualified enquiries.
What this means for premium brands
For a premium brand, one enquiry can be worth more than a month of generic traffic. That raises the stakes of the comparison question: when someone asks an assistant which studio, jeweller or chauffeur service to choose, are you in the answer, and is what it says about you correct? Google describes AI Mode as particularly helpful when “complex comparisons are needed”. The brands that appear there have a clear position and the evidence to back it up. Our guide to SEO for luxury brands covers that side in detail.
How we help
At Viralistic, SEO and AI search are one discipline, which we call SEO & AIO. One strategic lead shapes the positioning, the technical foundation and the content, so the same work earns rankings in Google and a place in AI answers. The sites we build in Astro are generated as static HTML, so every crawler can read them without running JavaScript. For SilverDrive, a premium chauffeur service, we moved the content strategy towards city-to-city trips after the first phase of its SEO programme, so the brand shows up both in Google and in AI answers such as ChatGPT and Perplexity.
The SEO vs GEO debate matters less than one practical question: when your ideal client searches or asks, do they find you? Read our SEO approach or plan a strategic call, and we will show you where your brand stands today.
Frequently asked questions
Is SEO dead now with AI?
No. Google’s own guide to generative AI search asks whether SEO is still relevant and answers with a clear yes, because AI Overviews and AI Mode are built on its core ranking and quality systems. What has faded is low-effort SEO: thin pages, keyword stuffing and content that repeats what everyone else says. Useful, well-built pages matter more than before.
Is GEO part of SEO?
In practice, yes. GEO rests on the same foundation as SEO: crawlable pages, indexed content, real expertise and trusted sources. What it adds is a focus on being quoted inside an AI answer instead of only being ranked in a list, plus new ways to measure that. Google’s guidance treats it as SEO applied to AI features, not as a separate discipline.
What is the difference between AEO and GEO?
AEO, answer engine optimisation, is the broader term for being chosen as the direct answer, in featured snippets, voice assistants or AI replies. GEO, generative engine optimisation, focuses on answers that a language model writes and cites. The tactics overlap almost entirely, and Google mentions both terms together when it explains which popular hacks you can ignore.
Is GEO the same as geo-targeting or local SEO?
No. Here GEO stands for generative engine optimisation and has nothing to do with geography. Local SEO is about appearing for searches with a location, such as a city or “near me”, through your Google Business Profile, reviews and local pages. The two do meet: Google says AI responses can include local business information, so an accurate Business Profile helps both.
Do I need a separate GEO agency?
Usually not. The work that earns AI citations is largely the work that earns rankings: technical access, strong content, sources and reputation. Splitting it across two agencies tends to create two strategies, two reports and gaps in between. Choose one partner who covers classic search and AI visibility together, measures both and can explain what changed and why. Our guide to GEO services lists what that work should include.
How do you measure GEO results?
Start with Google Search Console, where the Generative AI performance report shows impressions in AI Overviews and AI Mode per page, country and device. Add the AI Performance report in Bing Webmaster Tools for citations in Copilot. Track referral traffic from ChatGPT and Perplexity in your analytics, and judge everything on qualified enquiries rather than impressions alone.
