SEO in the AI era.
For twenty years, SEO meant getting a blue link ranked on a page of ten. That page is now often the second thing a customer sees — after an AI-generated answer that may never mention you at all. Here's what's changed, what hasn't, and what to actually do about it.
SEO in the AI era means optimising not just for traditional search rankings but for visibility inside AI-generated answers — Google's AI Overviews, ChatGPT, Gemini, Claude and Perplexity. This new discipline is called answer engine optimisation (AEO) or generative engine optimisation (GEO). The core shift: instead of only competing to rank, you're competing to be the source an AI cites when it answers a question. The tactics that help are largely an intensification of good SEO — clear direct answers, strong structured data, consistent and verifiable business information, genuine expertise (E-E-A-T), and technical accessibility — plus new habits like writing content that's easy to extract and quote. Fundamentals still matter; they matter more.
What this guide covers
What's actually changed
The mechanics of finding information are shifting under everyone's feet. Three changes matter for businesses:
AI Overviews. Google now often answers a query directly at the top of results with an AI-generated summary, drawing from multiple sources and citing some of them. For informational queries, this can mean the traditional blue links get pushed down or clicked less — and the sites cited in the overview capture the attention.
AI assistants as a starting point. A growing share of people now ask ChatGPT, Gemini, Claude or Perplexity a question before they ever open a search engine. "Who's a good plumber in Chelmsford?" or "how much should a small business website cost?" increasingly gets answered by an assistant that names specific businesses and sources — or doesn't name yours.
The unit of visibility is changing. It used to be a ranking position. Now it's increasingly a citation — being the source an AI trusts enough to reference. You can rank tenth and be cited, or rank first and be ignored. That's the game that's changed.
What hasn't changed: AI systems are trained on and retrieve from the web. They favour content that's clear, accurate, well-structured, and from sources that demonstrate expertise and trustworthiness. In other words, the things that always made good SEO now make good AI visibility too. The fundamentals didn't die — they got more important.
AEO and GEO: the new acronyms, explained
Two terms you'll increasingly hear:
AEO — Answer Engine Optimisation. Optimising content to be the direct answer to a question, whether that's a featured snippet, a voice assistant response, or an AI-generated answer. It's about structuring information so a machine can extract a clean, quotable answer.
GEO — Generative Engine Optimisation. The broader practice of improving how your brand and content appear within AI-generated responses across all the major systems — being included, cited, and represented accurately.
Don't overthink the labels. Both describe the same underlying goal: making your content the thing an AI reaches for when it answers a relevant question. And the methods overlap heavily with each other and with classic SEO. They're an evolution, not a revolution — which is good news, because it means the work compounds rather than replacing what you've done.
How to be cited by AI systems
Practical, in rough order of impact:
Answer the question directly and early. AI systems extract answers. A page that opens with a clear, self-contained answer to a specific question is far easier to cite than one that buries the answer under five paragraphs of preamble. This is why every guide on this site opens with a short-answer box — it's written to be extractable.
Structure for extraction. Clear headings that match real questions, concise definitions, comparison tables, step-by-step lists where appropriate, and FAQ sections. These give AI systems clean units of information to lift and attribute.
Ship strong structured data. Schema markup for your business, articles, FAQs, products and reviews hands machines verified facts rather than making them infer. Covered practically in technical SEO.
Be consistent and verifiable everywhere. AI systems cross-reference. If your business name, address, services and claims are consistent across your site, Google Business Profile, directories and structured data, you become a reliable entity worth citing. Inconsistency makes you risky to reference.
Demonstrate genuine expertise. Named authors with real credentials, original data, first-hand experience, specific detail. AI systems (like Google) favour content that shows E-E-A-T — and generic, could-have-been-written-by-anyone content is exactly what they skip.
Be technically accessible and fast. AI crawlers fetch pages under time constraints. A slow or hard-to-crawl page may simply not be read — the speed and crawl-budget point again.
Local businesses and AI search
For local service businesses, the AI shift has a specific shape. When someone asks an assistant "who's a good electrician near me?", the systems lean heavily on the same signals that power local search: a complete, active Google Business Profile, consistent business information across the web (your name, address and phone matching everywhere), genuine reviews, and clear service and location information on your site.
The businesses that win AI-assisted local queries are, overwhelmingly, the ones that already did local SEO properly — because that groundwork produces exactly the consistent, verifiable, well-reviewed entity that AI systems trust. If you've been meaning to sort your Google Business Profile and gather reviews, the AI era just raised the stakes. The mechanics are in our guide to what local SEO actually involves.
What to stop worrying about
Amid the noise, some things deserve less attention, not more:
Chasing every new acronym. AEO, GEO, LLMO, AIO — the labels multiply faster than the underlying practices change. Focus on the durable goal (be the clear, trustworthy, well-structured source) rather than the terminology.
Keyword density and old-school tricks. These were already dead for traditional SEO and are useless for AI, which understands meaning, not keyword counts. Write for humans, clearly.
Gaming the system. Attempts to manipulate AI citations tend to be short-lived and risky, the same way link schemes always were. The reliable long game is being genuinely worth citing.
Panic about traffic disappearing. Yes, some informational queries now get answered without a click. But commercial and local intent — someone ready to hire or buy — still overwhelmingly leads to a site visit, and being the cited source in the AI answer is often what earns that visit.
A practical checklist for 2026
| Action | Helps with | Effort |
|---|---|---|
| Open key pages with a direct, quotable answer | AI citations, featured snippets | Low |
| Add FAQ sections answering real questions | AEO, voice, AI Overviews | Low |
| Implement structured data (business, article, FAQ, review) | Rich results, AI extraction | Medium |
| Make business info identical across web + GBP + schema | Entity trust, local AI answers | Medium |
| Add named authors and real credentials | E-E-A-T, citation trust | Low |
| Ensure the site is fast and crawlable | AI + search crawler access | Medium |
| Publish original data or first-hand insight | Citation-worthiness | Higher |
| Build genuine reviews systematically | Local AI + trust | Ongoing |
Notice how much of that list is simply good SEO and good content, done deliberately. That's the honest headline of the AI era: the fundamentals didn't change, they got more valuable — and the businesses that had already done the work are the ones getting cited.
Frequently asked questions
What is SEO in the AI era?
Optimising for visibility both in traditional search rankings and inside AI-generated answers — Google's AI Overviews, ChatGPT, Gemini, Claude and Perplexity. The goal shifts from only ranking to being the source an AI cites when it answers a relevant question.
What is answer engine optimisation (AEO)?
Optimising content to be the direct answer to a question — a featured snippet, a voice-assistant response, or an AI-generated answer. It means structuring information so a machine can extract a clean, quotable answer, typically by answering questions directly and early.
What is generative engine optimisation (GEO)?
The practice of improving how your brand and content appear within AI-generated responses across the major systems — being included, cited and represented accurately. It overlaps heavily with AEO and with classic SEO fundamentals.
How do I get my business cited by ChatGPT or Gemini?
Answer questions directly and early on your pages, structure content for extraction (headings, tables, FAQs), ship strong structured data, keep your business information consistent and verifiable everywhere, demonstrate genuine expertise with named authors, and make the site fast and crawlable.
Are AI Overviews killing SEO traffic?
They reduce clicks on some informational queries by answering directly, but commercial and local intent still overwhelmingly leads to site visits. Being the cited source in an AI answer often earns that visit, so the emphasis shifts rather than the opportunity disappearing.
Does structured data help with AI search?
Yes. Schema markup hands AI systems verified facts about your business, articles, FAQs, products and reviews rather than making them infer, which makes your content easier to extract and cite accurately. Many sites still have none, making it a straightforward advantage.
Do traditional SEO fundamentals still matter with AI?
More than ever. AI systems are trained on and retrieve from the web, favouring content that's clear, accurate, well-structured and from trustworthy, expert sources — exactly what good SEO always produced. The fundamentals didn't die; they became the foundation of AI visibility.
How does AI search affect local businesses?
When people ask assistants for local recommendations, the systems lean on the same signals as local search: a complete Google Business Profile, consistent business information across the web, genuine reviews, and clear service and location content. Businesses that did local SEO properly are the ones AI recommends.
What is E-E-A-T and why does it matter for AI?
Experience, Expertise, Authoritativeness and Trust — qualities Google's raters and, effectively, AI systems use to judge content. Named authors with real credentials, original data, first-hand experience and specific detail make content more likely to be trusted and cited; generic content gets skipped.
Should I be worried about all the new AI SEO acronyms?
No. AEO, GEO and the rest multiply faster than the underlying practices change. Focus on the durable goal — being the clear, trustworthy, well-structured source — rather than chasing terminology, and the work will hold up as the labels come and go.
How is being 'cited' different from 'ranking'?
Ranking is your position in a list of links. Citation is being the source an AI references when it generates an answer. You can rank tenth and be cited, or rank first and be ignored — so the goal broadens from position to being genuinely worth referencing.
What's the single most effective thing I can do for AI visibility?
Answer real questions directly and early on well-structured pages, backed by genuine expertise and consistent, verifiable business information. Almost everything else follows from that — and it happens to be good SEO and good content done deliberately.
