SEO (search engine optimisation) helps your pages rank in search results. AEO (answer engine optimisation) helps your content become the direct answer in featured snippets, voice assistants and answer boxes. GEO (generative engine optimisation) helps AI tools such as ChatGPT, Gemini, Perplexity and Google's AI Overviews understand, trust and cite your brand.
| Compared on | SEO | AEO | GEO |
|---|---|---|---|
| Goal | Rank pages in search results | Be the direct answer to a question | Be cited or recommended by AI assistants |
| Where it shows | Google and Bing result lists | Featured snippets, People Also Ask, voice answers, AI Overviews | ChatGPT, Gemini, Perplexity, Claude, Copilot |
| Main levers | Technical health, content, links | Question research, answer-first writing, structured data | Crawler access, clear entity facts, independent mentions |
| How you measure it | Rankings, clicks, Search Console | Snippets held, impressions on question queries | Prompt tracking, AI referral traffic |
What does SEO optimise for?
Classic SEO is about earning a place in the list of links that a search engine shows. The goal is a click to your site. The work falls into three areas: technical health, so pages can be crawled and indexed; content, so each page clearly matches what people search for; and authority, mostly earned through links and mentions from other trusted sites.
SEO is still the foundation. Answer engines and AI tools draw heavily on the same indexed web, so a site that search engines struggle to read will struggle everywhere else too.
What does AEO optimise for?
Answer engine optimisation targets the moment when a search engine or assistant answers the question itself instead of only listing links. Think featured snippets, “People also ask” boxes and spoken answers from smart speakers.
The goal shifts from ranking a page to being chosen as the answer. That rewards content that states the answer early and plainly, in a format a machine can lift: a short definition, a numbered list of steps, a compact table. Structured data such as FAQ, HowTo and Product markup helps engines understand what each part of the page is.
What does GEO optimise for?
Generative engine optimisation is the newest of the three. It is about how large language models describe your business when someone asks them a question. These tools summarise many sources into one reply and sometimes cite a few of them.
GEO is less about one page and more about your whole footprint. AI tools form a view from your own site, review platforms, directories, news coverage, forums and any page that mentions you. Clear, consistent facts about who you are, what you offer and where you operate make it more likely that a model repeats them correctly. Original information, such as your own guides, data you have gathered or a distinct point of view, gives a model a reason to cite you rather than a competitor.
How do the three overlap?
They overlap far more than the acronyms suggest. All three reward the same core habits:
Pages that load quickly and can be crawled. Content written for a real question, with the answer near the top. Clear headings that break a topic into parts. Accurate structured data. A consistent brand name, address and description everywhere you appear. Genuine expertise, shown through author details, examples and specifics rather than vague claims.
The differences are mostly about emphasis. SEO cares most about the click and the ranking position. AEO cares about the format of the answer. GEO cares about your reputation across the wider web and how easy your facts are to quote.
Where do they pull in different directions?
There is one real tension. Answer boxes and AI summaries can satisfy a searcher without a visit to your site. If you only measure clicks, good AEO and GEO work can look like it is doing nothing, or even reducing traffic on some queries.
The answer is to measure more than sessions. Track impressions and snippet ownership in Search Console, branded search growth, direct enquiries, and how AI tools describe you when you ask them about your category. Visibility that leads to a later enquiry still counts.
What should you do first?
Start with technical SEO. Fix crawl errors, broken pages, slow templates, missing titles and duplicate content. None of the newer work pays off if engines cannot read the site properly.
Next, rework your most important pages for answers. For each one, write the question it answers as a heading and give a two or three sentence answer straight underneath. Add FAQ sections where people genuinely have follow-up questions, and mark them up correctly.
Then tidy your footprint. Make sure your business details match across your website, Google Business Profile, social profiles and industry directories. Encourage honest reviews. Look for places where your category is discussed and where a useful contribution would be welcome.
Finally, publish things worth citing. A clear guide, a comparison, a checklist or a well explained process is more likely to be quoted than a page of general claims.
Do you need separate teams or tools for each?
Usually not. For most businesses, AEO and GEO are extensions of good SEO rather than separate projects. The same person or team can plan content, fix technical issues and look after structured data. What changes is the checklist and the reporting, not the whole approach.
Be wary of anyone who promises guaranteed placement in AI answers. Nobody controls how these models choose sources, and their behaviour changes often. What you can control is the quality, clarity and consistency of the information you put out.
A simple way to think about it
SEO gets you found. AEO gets you quoted. GEO gets you remembered and recommended. Build them in that order and each layer supports the next.
If you would like a view on where your site stands across all three, technocity can run an audit and suggest a short, practical order of work.
