Key takeaways
- SEO earns rankings in search results; AEO earns direct answers; GEO earns mentions in AI-generated responses.
- All three rely on the same foundations: helpful content, clear structure and trust.
- AEO adds question-led, concise answers; GEO adds entity clarity and third-party corroboration.
- Most businesses should build on SEO and layer AEO and GEO practices on top.
SEO: search engine optimization
SEO is the practice of improving your website so it ranks higher in search engines like Google and Bing. It covers technical health (speed, crawlability, mobile friendliness), content that matches what people search for, and authority built through links and mentions.
The goal is a high position in the list of results, and the reward is a click to your website. Learn more about our SEO services.
AEO: answer engine optimization
AEO focuses on being the direct answer, not just a link. That includes featured snippets at the top of Google, “People also ask” boxes and answers read out by voice assistants.
AEO content is question-led and concise: the question as a heading, a clear answer in the first sentence or two, then supporting detail. FAQ sections and FAQ schema are typical AEO tools.
GEO: generative engine optimization
GEO is about appearing inside answers written by generative AI tools such as ChatGPT, Gemini, Perplexity and Google AI Overviews. These tools summarize information from many sources and often recommend specific businesses.
GEO emphasizes being clearly understood as an entity (who you are, what you do, where), keeping facts consistent everywhere, using structured data and earning mentions on sources AI models trust. Our guide to getting recommended by ChatGPT walks through the steps.
Side-by-side comparison
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank in results | Be the direct answer | Be mentioned and recommended by AI |
| Where it shows | Google & Bing results | Featured snippets, voice assistants | ChatGPT, Gemini, Perplexity, AI Overviews |
| Key tactics | Technical SEO, keywords, links | Questions, concise answers, FAQ schema | Entity clarity, consistency, citations, schema |
| Success measure | Rankings, traffic, leads | Snippets and answer ownership | Share of AI mentions and citations |
Example: one page optimized for all three
Imagine a dental clinic page targeting “teeth whitening in Manchester”.
- For SEO: the page has a clear title and heading with the service and city, loads fast, links to related treatments and earns links from local sites.
- For AEO: it includes questions such as “How much does teeth whitening cost in Manchester?” and “Is teeth whitening safe?”, each answered in one or two clear sentences before more detail, with FAQ schema.
- For GEO: the clinic’s name, address and treatments match its Google Business Profile and directories, it has recent reviews mentioning whitening, and it uses
DentistandServiceschema so AI tools can confidently recommend it.
One page, three kinds of visibility, with very little extra effort.
How they work together
These are not three separate projects. A well-structured page that answers a real question clearly, loads fast, uses schema and is referenced by other sites performs well in all three. Think of SEO as the foundation, AEO as the way you format answers, and GEO as the reputation and consistency layer that helps AI trust you.
How to write a page that answers well
Whichever acronym you focus on, the writing habits are the same:
- Lead with the answer. Put the direct answer to the page’s main question in the first two sentences.
- Use real questions as headings. Take them from sales calls, support emails and “People also ask” boxes.
- Be specific. Ranges, timeframes, locations and examples are more useful, and more quotable, than generalities.
- Show expertise and experience. Explain how you do things, mention real situations and name who wrote or reviewed the content.
- Structure for scanning. Short paragraphs, lists, tables and summaries help readers and machines alike.
- Keep it current. Update prices, dates and facts so the page stays trustworthy.
How to measure each one
| What to track | Where | |
|---|---|---|
| SEO | Rankings, organic traffic, leads from organic search | Google Search Console, GA4, rank trackers |
| AEO | Featured snippets and “People also ask” appearances for your target questions | Search Console, SEO tools with SERP feature tracking |
| GEO | How often AI assistants mention or cite you for buyer prompts | Monthly prompt testing across ChatGPT, Gemini, Perplexity and AI Overviews |
Common misconceptions
- “SEO is dead because of AI.” AI tools rely heavily on well-structured, authoritative web pages, which is exactly what good SEO produces.
- “GEO is just adding an llms.txt file.” Helper files may be useful, but clarity, consistency, schema and reputation matter far more.
- “AEO means short content.” AEO means short answers, followed by the depth people and search engines still need.
Where should your business start?
- Fix the SEO foundations: technical health, one page per service and content that matches search intent.
- Add AEO formatting: FAQ sections and answer-first introductions on your key pages.
- Layer in GEO: schema, consistent business information and mentions on trusted sites, then track your AI visibility monthly.
Our AI search optimization service combines all three in one plan.
Frequently asked questions
No. AI tools often draw on pages that already rank well in search, so SEO remains the foundation. GEO adds practices that help AI models understand, trust and cite you.
AEO stands for answer engine optimization: structuring content so search engines and voice assistants can use it as a direct answer.
Usually not. Well-structured, question-led content with schema and strong references serves all three.
