Short answer
SEO aims to rank your pages in search results. AEO aims to get your content chosen as the direct answer. GEO aims to get your brand named inside answers an AI tool writes. The terms overlap and nobody owns the definitions. Good SEO still feeds all three; what’s new is checking the answers themselves.
GEO vs SEO vs AEO in plain English
Nobody owns these definitions, and writers stretch them. These are the common meanings.
- SEOSearch engine optimization. Getting your pages to rank in a list of results so people click through.
- AEOAnswer engine optimization. Getting your content chosen as the direct answer, in a snippet, a voice reply or an AI summary.
- GEOGenerative engine optimization. Getting your brand named, and described accurately, inside answers that an AI tool writes.
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank pages in results | Be chosen as the direct answer | Be named inside an AI-written answer |
| Where it shows up | A list of links | Snippets, voice replies, AI summaries | Chat and AI search answers |
| Main lever | Pages and links | Clear, quotable answers | Pages, plus sources on other sites |
You’ll also see LLMO and “AI search optimization”. They point at roughly the same idea as GEO.
AEO vs SEO: where they overlap
A lot of the work is shared. Pages need to be crawlable, clear and accurate, whichever acronym you prefer.
Google says as much about its own AI features. Its Search Central guidance says nothing extra is needed to appear in AI Overviews or AI Mode, beyond being indexed and eligible for a snippet.
GEO vs AEO: what is actually new?
- No position oneAn AI answer names a few brands in an order that keeps changing. SparkToro found the same order came back about once in a thousand runs.
- Sources beyond your siteIn one agency study of software questions, ChatGPT cited a tool’s own site only 11.6% of the time. The rest came from other people’s pages.
- Measurement is samplingSearch Console reports real clicks. For AI answers you sample questions and count how often you appear.
What lines up with AI visibility?
Ahrefs compared 75,000 brands against how often they’re mentioned in Google AI Overviews. How much a brand gets talked about across the web lined up best.
Backlinks, the old SEO favorite, came last of the five. Ahrefs is careful to say this shows a link and not a cause, and it covers Google rather than ChatGPT.
What should a small software team do?
You don’t need a separate team. Keep doing SEO and add a small monthly habit.
- Pick ten questions your buyers ask, in their words.
- Run them in ChatGPT several times each and record who’s named, recommended and cited.
- Fix what the answers get wrong: an old price, a missing feature, a page that never says who you’re for.
- Look at the cited pages. Contact the ones that compare your category and leave you out.
Which word should you use on your own site?
Use the words your buyers use. Most of them type none of these three terms. They ask “which tool should we pick for a ten-person team?” and expect a straight answer.
Vendors favor whichever term they sell. If someone insists their word is the only real one, ask what they measure and how.
Write for the question and the vocabulary takes care of itself.
Key takeaways
- The three terms overlap, and nobody owns the definitions.
- Good SEO still feeds AI answers: crawlable, clear, accurate pages.
- What’s new is measuring answers by sampling, not by rank.
- A small team needs a monthly habit, not a second strategy.

Common questions
Is GEO replacing SEO?
Not on current evidence. Google says its AI features rely on the same indexing and eligibility as normal Search. Treat GEO as an extra layer of checking on top of SEO, not a replacement for it.
Is AEO the same as GEO?
They overlap. AEO usually means getting picked as the one direct answer. GEO usually means being named inside a longer AI-written answer. Many writers swap the two words, so check which meaning a source intends.
Which should a small software company do first?
SEO fundamentals first: clear pages, a public price, accurate comparison content. Then run a monthly check of your buyer questions in ChatGPT. That small habit covers most of what GEO asks of a team your size.
Do I need new tools for GEO?
Not at first. A spreadsheet and ChatGPT cover ten questions. A tool starts to help once you track more questions or more competitors, or want to compare one month with the next.
