GEO vs SEO vs AEO: what's the difference?
SEO wins rankings, AEO wins direct answers and GEO wins mentions in AI assistants. How they differ, how to measure each and where to start.
GEO vs SEO vs AEO, in one paragraph.
SEO (search engine optimization) helps your pages rank in search results. AEO (answer engine optimization) helps your content become the direct answer to a question, such as a featured snippet. GEO (generative engine optimization) helps your brand get named and cited in AI assistants like ChatGPT, Gemini, Claude and Perplexity. All three share the same base: useful, clear pages.
How each one works
SEO is the oldest of the three. Search engines crawl your pages, judge relevance and quality, and rank them. You win clicks from a list of blue links.
AEO grew with featured snippets, voice assistants and "People also ask" boxes. The search engine lifts a short answer from your page and shows it directly. You win when your page states the answer cleanly.
GEO is the newest. The term comes from a 2023 research paper by Aggarwal and colleagues. An AI assistant writes its own answer from many sources. You win when it names your company or cites your page.
GEO vs SEO vs AEO comparison
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank pages high in search results | Be the direct answer to a question | Be named or cited in AI-written answers |
| Where it shows | Google and Bing results pages | Featured snippets, answer boxes, voice | ChatGPT, Gemini, Claude, Perplexity, AI Overviews |
| What wins | Relevance, links, technical health, intent match | Short, direct answers near the top of a page | Clear facts, trusted mentions elsewhere, crawler access |
| How you measure | Rankings, clicks, impressions in Search Console | Snippets won, answer box presence | How often you are named, which pages are cited |
How GEO differs from SEO in practice
With SEO you see one ranked list. With GEO there is no list. Each assistant writes a fresh answer, and it can change between runs.
That changes measurement. You cannot just check a rank. You ask the same buyer questions in each assistant, again and again, and record who is named.
It also changes what counts. AI assistants lean on what other sites say about you. A mention in a trusted industry list can matter as much as your own page.
Examples
A B2B payroll company might target three things:
- SEO: rank for "payroll software for small business" with a strong product page.
- AEO: win the snippet for "how often do you run payroll" with a clear two-line answer.
- GEO: be named when a buyer asks ChatGPT "what payroll tools suit a 50-person company?"
The same well-written page can serve all three. The difference is in how you check results.
Is GEO replacing SEO?
No. AI assistants with web search still find pages through search indexes and crawlers. If your pages are hard to crawl or thin, they are hard to cite. Good SEO is the base that GEO builds on.
What changes is attention. Some buyers now ask an assistant before they search. So it is worth tracking both.
Common mistakes
- Treating them as three separate projects. Most of the work overlaps. Start with one content plan.
- Blocking AI crawlers by accident. Check robots.txt. OpenAI says sites that block OAI-SearchBot will not be shown in ChatGPT search answers.
- Checking once and stopping. AI answers vary. Track the same questions every week.
- Writing only for machines. Pages still need to convince a person who clicks through.
How to start
- Write down twenty questions your buyers actually ask.
- Check Search Console for which of them you already rank on.
- Ask each question in ChatGPT, Gemini, Claude and Perplexity. Note who is named.
- Fix the gaps: add clear answers, compare options honestly, get listed where your buyers look.
- Repeat the checks on a schedule.
