What does AI SEO mean?
AI SEO means optimising your brand and content so AI search tools — ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews — recommend and cite you, alongside ranking well on Google. It is the umbrella term for a cluster of related disciplines.
Under that umbrella sit two more specific practices. Generative engine optimisation (GEO) targets generative AI models such as ChatGPT and Perplexity, aiming to get your facts quoted inside the answer the model writes. Answer engine optimisation (AEO) targets answer surfaces such as Google AI Overviews, featured snippets and People Also Ask, aiming to get your content lifted directly into the answer box. Both sit on top of classic technical SEO, which remains the retrieval foundation for all of them.
How is AI SEO different from traditional SEO?
Traditional SEO optimises a page to rank in a list of links. AI SEO optimises your brand and facts to be cited and recommended inside an AI-written answer, in addition to ranking. The two share a technical foundation but measure success differently.
| Dimension | Traditional SEO | AI SEO |
|---|---|---|
| Goal | Rank a page in Google’s results | Be cited and recommended in AI answers, plus rank |
| Unit optimised | Individual pages and keywords | Your entity, facts and pages across the web |
| Key signals | Backlinks, keywords, technical health | Entity consistency, extractable facts, schema, citations in AI-read sources |
| How success is measured | Ranking position, organic clicks | Share of voice in AI answers, plus rankings |
| Engines | Google, Bing organic results | ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews |

Why does AI SEO matter for UK businesses now?
AI SEO matters now because search demand for it is rising fast and because AI assistants increasingly answer buying questions before a user reaches Google. UK searches for “ai seo agency” grew from 110 to 480 a month over 12 months, and “ai visibility” grew from 10 to 140 a month over the same period (SE Ranking, UK, 2026).
Over half of UK adults (54%) now use AI assistants such as ChatGPT, Copilot or Gemini for everyday questions, up from 31% a year earlier (Ofcom, 2025), and when an AI answer appears above Google’s organic results, clicks to those organic results roughly halve — 8% of visits with an AI Overview versus 15% without (Pew Research Center, 2025). The direction is consistent: fewer clicks reach the classic blue links, and more decisions happen inside an AI answer that names only a handful of brands.
GEO, AEO, LLM SEO — what’s the difference?
GEO, AEO and LLM SEO are three framings of the same underlying goal — getting AI systems to cite your brand — each aimed at a different surface. GEO targets generative engines broadly; AEO targets answer boxes and snippets; LLM SEO frames the same work around specific language models.
Generative engine optimisation (GEO) is the broadest of the three: making your content citable by any system that generates a written answer. Our complete GEO guide covers the mechanics in full.
Answer engine optimisation (AEO) focuses specifically on answer surfaces — Google AI Overviews, featured snippets, People Also Ask — where content is lifted rather than generated from scratch. See our AEO guide.
LLM SEO is the same discipline as GEO, described from the model’s side: how do you get ChatGPT, Claude and Perplexity specifically to cite you. Our LLM SEO guide covers this engine by engine.
How do AI engines decide which brands to recommend?
AI engines recommend brands whose facts are consistent, easy to verify and repeated across trusted sources. Four signals matter most: a clear entity, extractable content, corroboration, and structure.
A clear entity means your business name, one-line description and category are identical everywhere — your site, Google Business Profile, LinkedIn, directories. Our guide to entity SEO for AI search explains this in depth. Extractable content means facts written as standalone sentences a model can quote without the surrounding paragraph. Corroboration means the same claim appears across multiple trusted sources — reviews, directories, press, communities — not just your own site. Structure means schema markup, clean headings and FAQ blocks that map a claim to its evidence. Our post on where AI answers come from walks through how engines assemble a cited response from these pieces.
How do you do AI SEO? A starter checklist
Getting started with AI SEO takes six steps: measure your baseline, fix your entity, add machine-readable signals, structure your content for extraction, earn citations, and re-measure. None of the first steps require an agency.
- Measure your AI share of voice. Ask ChatGPT, Perplexity, Gemini and Claude your key buying questions and record whether and how they mention you.
- Fix your entity. Make your business name, one-line description and category identical across your site, Google Business Profile, LinkedIn and directories.
- Add schema and an llms.txt file. Organization, Article and FAQPage schema, plus an llms.txt file, help machines identify and parse your content.
- Earn citations in the sources AI reads. Relevant directories, reviews, expert communities and credible press coverage.
- Publish answer-structured content. Question-form headings, a direct answer immediately underneath, tables for comparisons.
- Re-measure monthly. AI engines re-crawl and re-cite on their own schedule, so track change rather than expecting a one-off fix.

Can you do AI SEO yourself, or do you need an agency?
You can do much of the first pass yourself — fixing your entity, adding schema, writing answer-structured content are all things a competent in-house marketer can complete without external help. Where specialists tend to add most value is measurement at scale, prompt research across five engines, and prioritising which fixes move the needle fastest.
If you want a baseline before deciding either way, NeuralGen’s AI SEO agency services start with the same free scorecard we’d recommend you run yourself. It shows where you currently appear against competitors across ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews, with no obligation to buy anything next.
