SEO (search engine optimisation) is how you get found in Google and Bing. AEO (answer engine optimisation) is how you get quoted in AI Overviews, featured snippets and voice results. GEO (generative engine optimisation) is how you get named and cited in longer answers from ChatGPT, Perplexity, Gemini, Claude and Copilot. They are not three agencies to hire. They are three ways to be found — for the same page.
You write a great blog post. You publish it. You wait. Nothing happens. Not because your content is bad. Because you optimised for the wrong place.
In 2016, there was one place to be found: Google's 10 blue links. In 2026, there are three: someone Googles you; someone asks Google's AI Overview; or someone asks ChatGPT, Perplexity, Gemini or Claude. If you only show up in one of those, you are invisible in the other two — and your customer does not know you exist.
Let's break them down in plain English.
1. SEO — search engine optimisation — get found
What it is: Getting your pages to rank on Google and Bing.
What you do: Keywords, backlinks, technical SEO, speed, mobile, internal links.
Goal: Rank + click.
SEO is still the foundation. If Google cannot crawl you, index you and understand you, nothing else works.
Google's own May 2026 guidance puts it clearly. From the official guide to optimising for generative AI features on Google Search:
From Google Search's perspective, optimizing for generative AI search is optimizing for the search experience, and thus still SEO.
That line is from Google Search Central's AI optimisation guide, announced in May 2026. Translation: don't throw away SEO. Build on it.
You need SEO if: your site isn't ranking, isn't indexed, or is slow and messy.
2. AEO — answer engine optimisation — get quoted
What it is: Getting your page chosen as the answer when a search engine answers the question itself.
Where you appear: Google AI Overviews, featured snippets and voice search.
What you do: FAQ sections, schema, short answers and clear headings.
Goal: Be the answer.
AEO isn't about ranking number one. It's about being the passage Google lifts and shows directly — even if the person never clicks through.
You need AEO if: you rank, but you get no answer-box or AI Overview appearances.
3. GEO — generative engine optimisation — get remembered
What it is: Getting your business named and cited inside the longer answers written by generative AI.
Where you appear: ChatGPT, Perplexity, Gemini, Claude and Copilot.
What you do: Statistics, quotations, citations, original research and a clear entity (who you are, what you do).
Goal: Be cited and recommended.
GEO tries to get you quoted inside an answer an AI model writes — not just rank a blue link. This is the newer piece, and the one most small businesses miss completely.
You need GEO if: buyers are asking ChatGPT or Perplexity and your brand never shows up.
Three researched stats that change what you fix first
Don't guess. These figures come from published research — and one popular claim does not.
1. GEO tactics can lift visibility by up to 40% in a controlled study. The GEO paper by Aggarwal, Murahari and colleagues (Princeton, Georgia Tech, IIT Delhi and the Allen Institute for AI; arXiv:2311.09735, later published at KDD 2024) found that adding statistics, quotations and citations can boost a source's visibility in generative-engine answers by up to 40%. The top methods improved a position-adjusted word-count metric by about 30–40% against an unmodified baseline. That is visibility inside generated answers in the study, not a guaranteed lift in traffic or Google rankings.
2. 81% of cited pages had some schema — that does not prove schema causes citations. AccuraCast (September 2025) analysed 9,000 citation sources from more than 2,000 prompts across ChatGPT, Google AI Overviews and Perplexity. 81% of those cited pages included some form of schema. The same study found FAQPage schema on only 1.8% of cited sources, and the authors warned that the 81% figure should not be read as proof that schema is required to get cited. A separate claim that schema plus FAQ blocks brings around 44% more AI citations could not be traced to a primary study, so we are not repeating it as a research result. Schema is still worth adding for Google Search features and for clarity. It is not a proven shortcut to more AI citations.
3. 44% of ChatGPT citations came from the first 30% of the page. An analysis of 18,012 verified ChatGPT citations, reported by Kevin Indig in February 2026 and covered by Search Engine Land, found that 44.2% of citations came from the first 30% of the content — roughly the first third of the page. 31.1% came from the middle, and 24.7% from the final third, with a sharp drop near the footer.
Read that again: it is not about writing more. It is about making the first third of your page citable. Put your best, clearest answer near the top.
SEO vs AEO vs GEO — a quick table
- Goal. SEO: rank + click. AEO: be the answer. GEO: be cited + recommended.
- Where. SEO: Google and Bing results. AEO: AI Overviews, snippets and voice. GEO: ChatGPT, Perplexity, Gemini and Claude.
- What wins. SEO: keywords, backlinks, technical SEO. AEO: FAQ, schema, short answers, clear headings. GEO: stats, quotes, citations, original research.
- Success looks like. SEO: a ranking and a click. AEO: your words in the answer box. GEO: your brand named or cited.
So which one do you need?
Start with SEO if your website is not yet solid — if pages aren't indexed, titles are vague, or the site is slow and hard to crawl.
Add AEO if you already rank but you rarely appear in answer boxes or AI Overviews.
Add GEO if buyers are asking ChatGPT or Perplexity and your brand never shows up.
Most businesses in 2026 need all three — for the same page, not as three separate strategies.
What to do next — a 5-minute check
- Google your main service plus your town or niche. Are you there?
- Ask ChatGPT the same question your customer would ask. Who gets named?
- Ask Perplexity the same question. Who gets cited?
- Open your homepage. Is your best answer in the first third of the page?
- Do you have an FAQ and schema? If not, that is a useful first fix for people and for Google Search features — just don't expect it to guarantee AI citations.
If you answered "no" to questions 2 or 3, that is your GEO gap.

Frequently asked questions
What is the difference between SEO, AEO and GEO?
SEO is how you get found in Google and Bing. AEO is how you get quoted in AI Overviews, featured snippets and voice results. GEO is how you get named and cited in longer answers from tools such as ChatGPT, Perplexity, Gemini and Claude. They are three ways to be found for the same page, not three separate agencies.
Do I still need SEO if I care about ChatGPT and AI Overviews?
Yes. SEO is still the foundation. If a search engine cannot crawl, index and understand your pages, the other two are much harder. Google's May 2026 guidance says that, from Google Search's perspective, optimising for generative AI search is still SEO.
Does adding FAQ schema automatically get more AI citations?
No proven automatic lift. AccuraCast found that 81% of cited pages had some schema, but FAQPage schema appeared on only 1.8% of those sources, and the authors warned that the 81% figure does not prove schema causes citations. Schema is still useful for Google Search features and for making a page clearer. It is not a shortcut to a measured 44% citation increase.
Where on the page should I put my best answer?
Near the top. An analysis of 18,012 verified ChatGPT citations, reported by Kevin Indig in February 2026, found that 44.2% came from the first 30% of the page. Put a clear, citable answer in the first third, then add supporting detail.
