Where the two terms came from.
Both labels emerged as researchers and marketers tried to name the same new challenge: search changed, and the old SEO vocabulary didn't quite fit.
AEO — Answer Engine Optimization — came first, tied to voice assistants and featured snippets. The idea was that Siri, Alexa and Google's answer boxes work differently from classic search results: they speak one answer, not ten. Optimizing to be that one answer needed a name.
GEO — Generative Engine Optimization — emerged as large language models like ChatGPT, Perplexity and Gemini took over the conversation. These tools generate a written response by synthesizing sources, rather than just pulling a snippet from the top-ranked page. Researchers studying how citation patterns worked in these systems coined GEO to distinguish that behavior from the older answer-engine model.
By 2025, the two terms are used almost interchangeably in practice. Some teams prefer AEO when they mean any AI that gives a single spoken or typed answer. Some prefer GEO when they mean large language models specifically. Neither camp is wrong; the underlying work is the same. Read more about what GEO is and what AEO is if you want the full definitions side by side.
Where the terms diverge — and where they meet.
There are small technical distinctions worth knowing, even if the day-to-day work overlaps almost entirely.
AEO: structured answers from a single source.
Traditional answer engines like Google's featured snippet, voice results, and early Siri pull a direct answer from one page. AEO means writing a passage that directly answers the question in a self-contained way — short, factual, no throat-clearing. This still matters inside Google's ecosystem.
GEO: synthesis across multiple sources.
ChatGPT, Perplexity, Gemini and similar tools pull from several sources, reason over them, and write an original response. GEO means giving the model enough consistent, quotable material across your site, your Google Business Profile and third-party mentions that it includes you in its synthesis. See how GEO works for the full mechanics.
The work is the same either way.
Whether you call it AEO or GEO, you need: clear entity data, answer-shaped content, consistent NAP across directories, strong schema markup, and a credible off-site footprint. A site built to be quoted by one type of engine is built to be quoted by all of them.
Use the word your audience already knows.
Neither AEO nor GEO is more correct. They describe overlapping phenomena, and the practical playbook barely changes depending on which you pick.
If you are talking to a marketer who comes from an SEO background, GEO tends to land better — it signals that this is a new discipline distinct from classic search optimization. If you are talking to someone focused on voice search or conversational interfaces, AEO is more familiar. If in doubt, say "AI visibility" and both camps understand you immediately.
At TRIVOX, we optimize for the outcome: your business named in the answer. We use whichever label fits the conversation, and we focus on the signals that move the needle across all major assistants — ChatGPT, Perplexity and Gemini included. The label is secondary; the citation is what counts.
The result is the same regardless of term.
Whether your agency calls it AEO or GEO, the deliverables and outcomes are consistent.
Named in AI answers
Assistants like ChatGPT and Gemini include your business name when someone in your city asks for a recommendation in your category.
Citable content
Your site contains clear, direct answers that models can quote verbatim, reducing the chance they hallucinate or skip you.
Cross-platform consistency
Your name, address, services and description match across every surface a model checks — site, GBP, directories, reviews.

Questions, answered.
What is the difference between AEO and GEO?
AEO (Answer Engine Optimization) historically referred to optimizing for single-answer engines like featured snippets and voice assistants. GEO (Generative Engine Optimization) refers to optimizing for large language models that generate written responses by synthesizing multiple sources. In practice today, the work is nearly identical and most teams use the terms interchangeably.
Do I need to do both AEO and GEO?
You don't need to treat them as separate workstreams. A site built to be clearly readable and quotable by AI will perform in both contexts. Focus on entity clarity, answer-shaped content, consistent facts across the web, and strong schema — that covers both.
Is GEO the same as SEO?
No. SEO optimizes for a ranked link in a list of search results. GEO optimizes for being named inside the text a generative AI produces. They share some technical foundations — a clean, well-indexed site helps both — but GEO adds a layer SEO alone doesn't address.
Which assistants does GEO/AEO affect?
The main targets are ChatGPT (with and without search), Perplexity, Google Gemini, Google's AI Overviews in search results, and Microsoft Copilot. As AI assistants become the first stop for product and service recommendations, visibility in these tools directly affects how many new customers find you.
How does TRIVOX approach AEO and GEO?
We treat them as one discipline under the umbrella of AI visibility. We audit what each major assistant currently says about your business, fix the gaps in entity data and on-site content, build consistent off-site signals, and track citation frequency over time.
