What Is GEO or AEO, and Is It Different From SEO?

By CiteMonthly editorial team · CiteMonthly · Published 23 October 2026

Short answer: "GEO" means generative engine optimization and "AEO" means answer engine optimization. Both are names for work aimed at being seen in AI search experiences [1], such as Google's AI Overviews and AI Mode [2] or ChatGPT search [5]. Google's position is clear: "From Google Search's perspective, optimizing for generative AI search is optimizing for the search experience, and thus still SEO" [1]. Google says there are "no additional requirements" to appear in AI Overviews or AI Mode [2], and it lists several popular "AEO/GEO hacks" you can ignore [1]. Outside Google, a few practical things do differ. ChatGPT, for example, has its own search crawler that your site has to allow [5] [6]. So GEO and AEO are mostly new labels for SEO, plus a short list of AI-specific checks.

What do GEO and AEO actually stand for?

Google's own guide to generative AI features spells them out: "AEO" stands for "answer engine optimization" and "GEO" for "generative engine optimization." Google describes both as "terms you may see used to describe work specifically focused on improving visibility in AI search experiences" [1].

In plain terms (our wording), "answer engine" and "generative engine" both mean a tool that writes an answer to your question instead of only showing a list of links. Google's AI Overviews and AI Mode are examples [2]. So is ChatGPT when it searches the web and shows links to its sources [5].

SEO, for comparison, is defined in Google's SEO Starter Guide as "helping search engines understand your content, and helping users find your site and make a decision about whether they should visit your site through a search engine" [4].

Our opinion: in everyday use, GEO and AEO mean the same thing under different labels. Ask anyone who uses them what work they actually mean.

Is GEO different from SEO, according to Google?

For Google Search, no. Google's guide opens its AI section with the question "Is SEO still relevant for generative AI search?" and answers: "In short, yes!" The reason it gives is that its generative AI features "are rooted in our core Search ranking and quality systems" [1].

Google names two techniques its AI features use to pull content from the Search index [1]:

Retrieval-augmented generation (also called grounding). The AI relies on Google's core Search ranking systems to fetch relevant, up-to-date pages from the index. It then generates an answer and shows clickable links to pages that support it.
Query fan-out. The model runs several related searches at once to gather more results. Google's example: for "how to fix a lawn that's full of weeds," the extra searches might include "best herbicides for lawns" and "remove weeds without chemicals."

Our inference (not a Google quote): if the AI answer is built from pages that Google's normal ranking systems find, then a page that does well in normal Search is starting from the same place. That is why Google keeps calling this "still SEO."

What does Google say you need to appear in AI Overviews and AI Mode?

The same things you need for regular Search. Google's AI features page says: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary" [2].

To be eligible as a supporting link, a page must be indexed and eligible to be shown in Google Search with a snippet, meeting the Search technical requirements [2]. Google also warns that meeting every requirement does not mean Google will crawl, index or show the page: "Indexing and serving isn't guaranteed" [2].

The SEO basics Google lists for AI features include [2]:

Allowing crawling in robots.txt and by your CDN or hosting setup.
Making content easy to find through internal links on your site.
Giving visitors a good page experience.
Putting important content in text form.
Supporting text with good images and video where it fits.
Making sure structured data matches the visible text.
Keeping your Merchant Center and Business Profile information up to date.

For local businesses, Google's guide adds that AI answers can include information about local businesses, and that Merchant Center and Google Business Profiles "can help your products and services to be visible in both AI responses and other Google Search results" [1].

Above all, Google says content people find "unique, compelling, and useful will likely influence your website's presence in generative AI search in the long run more than any of the other suggestions in this guide" [1].

Which "GEO hacks" does Google say you can ignore?

Google's guide has a "mythbusting" section. It says that while the terms AEO and GEO are common online, "many suggested 'hacks' aren't effective or supported by how Google Search actually works" [1]. For Google Search, it lists these as things you can ignore [1]:

llms.txt and other "special" AI files or markup. Google Search doesn't use them, and creating one "will neither harm nor help" your visibility in Google Search. We covered this in Do you need an llms.txt file?.
"Chunking" content into tiny pieces. Google says there's no requirement to do this and "There's no ideal page length."
Rewriting content just for AI. Google says AI systems understand synonyms and general meaning, so you don't need every keyword variation.
Seeking inauthentic "mentions" around the web. Google says this "isn't as helpful as it might seem," because its AI features depend on core ranking systems and on systems that block spam.
Overfocusing on structured data. Google says it isn't required for generative AI search and there's no special schema.org markup to add. It is still useful for rich results.

Google also warns against making a separate page for every way someone might phrase a search, including fan-out queries. If you do that mainly to manipulate rankings or AI answers, Google says it violates its scaled content abuse spam policy [1].

Is anything different for ChatGPT and other AI assistants?

Yes, a few practical things, because ChatGPT search is not Google Search.

Crawler access. OpenAI says that to make a website eligible for ChatGPT search, you should allow its search crawler, OAI-SearchBot, and make sure your host or CDN allows traffic from OpenAI's published IP addresses [5]. OpenAI's crawler page says sites that block OAI-SearchBot "will not be shown in ChatGPT search answers, though can still appear as navigational links" [6]. That setting is separate from GPTBot, which relates to model training. You can allow one and block the other [6]. Our checklist is in Is your website blocking ChatGPT?.

No guarantees there either. OpenAI says ChatGPT ranks search results "using multiple factors intended to help users find relevant, reliable information. Placement is not guaranteed" [5].

Our inference (not an OpenAI quote): the overlap with SEO is large. You still need crawlable pages that answer real questions. The differences are mostly access (which bots you allow) and measurement (where you check results). The OpenAI pages we opened document no separate secret recipe.

So what actually changes for a small business?

This section is our opinion, based on the pages cited above.

What stays the same: useful, original pages about your services and area, accurate business details, and a site that search crawlers can reach. Be patient: Google's starter guide says some changes take hours and others months, and you usually want to wait a few weeks before judging [4].

What is new:

Check bot access beyond Googlebot. If you want to appear in ChatGPT search, OAI-SearchBot must be allowed [5] [6].
Measure AI visibility where it is reported. Google says traffic from AI Overviews and AI Mode is counted in Search Console's Performance report under the "Web" search type [2]. Its AI guide also points to a Generative AI performance report in Search Console [1].
Look at the answers themselves. Ask the AI tools the questions your customers ask and note who is named and which sources are cited. Our step-by-step method is in How to check whether ChatGPT mentions your business.

How do you judge someone selling GEO or AEO services?

Google's "Do you need an SEO?" page now lists "Optimizing for generative AI" among the useful services SEOs can offer [3]. It also says: "If you run a small local business, you can probably do much of the work yourself" [3].

If you do hire help, Google suggests asking questions like these [3]:

Do they cite official Google documentation as evidence for their recommendations?
If they offer AEO or GEO advice, does it match Google Search's official guidance on generative AI features?
Do they use tools that match Google's guidance?

The same page warns: "No one can guarantee a #1 ranking on Google" [3]. It says Google doesn't endorse third-party SEO tools, and that those tools don't have access to Google's internal ranking data [3]. The AI guide says the same about AI: "No third-party tool has access to our internal ranking or AI systems" [1].

Google also tells readers to be wary of SEO firms that email you out of the blue [3]. That includes emails from us. Judge any offer, ours included, by whether it cites official documentation and avoids promises.

Frequently asked questions

Are GEO and AEO the same thing?

Google introduces them together as two terms for work aimed at visibility in AI search experiences [1]. In our opinion, the difference is mostly the label, not the work.

Do I need a separate GEO strategy for Google AI Overviews?

Not according to Google. It says there are no additional requirements or special optimizations for AI Overviews or AI Mode [2], and that optimizing for generative AI search is "still SEO" [1].

Can anyone guarantee my business will appear in AI answers?

No. Google says indexing and serving aren't guaranteed [2], and OpenAI says placement in ChatGPT search is not guaranteed [5].

Do I need special schema markup or an llms.txt file for AI search?

Not for Google Search. Google says there's no special schema.org markup to add and that Google Search ignores llms.txt files [1] [2].

What is the one AI-specific thing worth checking first?

In our opinion: make sure you aren't blocking the search crawlers you want, including Googlebot and OAI-SearchBot [2] [5] [6]. If a crawler can't reach your pages, nothing else on this list helps for that tool.
