SEO, AEO & GEO: What the Heck Does It All Mean?

SEO is how you make your website easy to find in search. AEO and GEO are newer names for making that same website easy for answer features and AI tools to understand. Google's own guide says SEO best practices still apply to its AI features, so for most small businesses these three terms describe one job, not three.

I get why this feels like alphabet soup. So here is the plain version of each term, what Google itself has said about them, and what I would do on a small business website.

What does SEO actually mean?

SEO stands for search engine optimization. It is the work of making your website easy for Google and Bing to find, read and understand, and useful enough to show when someone searches for what you offer. That covers the technical side (can search engines crawl your pages, and do they load fast on a phone), the page side (clear titles and headings) and the trust side (accurate business details and content that shows real experience).

Expect to wait. Google's SEO Starter Guide says some changes can take effect in a few hours while others can take several months.

What is AEO, or answer engine optimization?

AEO means shaping your content so a search or answer system can pull a clear answer out of it. The classic examples are the boxed answer at the top of a Google results page, "People also ask" questions, voice assistants and now AI-written answers. In practice, it mostly means writing the way people ask.

Picture a hypothetical baker who takes custom orders. Her page opens with "We craft memorable moments." A more useful page opens by answering the question a customer would type: yes, she does custom orders, and here is how far ahead to place one. A person skimming gets the answer right away, and so does a machine.

One caution: AEO is an industry label, and Google's guide notes that many tricks sold under labels like it are not effective or supported by how Google Search works.

What is GEO, or generative engine optimization?

GEO is the newest of the three. It is the practice of making your content clear, well organized and trustworthy enough to be useful to AI systems that write their own answers, such as ChatGPT, Perplexity and Google's AI Overviews. The term comes from a 2023 research paper whose methods were tested on a benchmark the authors built, not on live ChatGPT or Google, so I would not treat any number from it as a promise about your site.

The vocabulary is still unsettled. Some people say GEO, some say AEO, and others say LLMO or AI optimization, and the terms overlap. Nobody can promise you a mention in ChatGPT, Google's AI features, Perplexity or any other AI system. Anyone who does is guessing, or selling something.

How do SEO, AEO and GEO compare side by side?

They aim at different places your content can appear, but they draw on the same habits.

What does Google itself say about AEO and GEO?

Google says its AI features are built on the same systems as regular Search, so SEO best practices still apply. In its 2026 guide, Optimizing your website for generative AI features on Google Search, it says: "The best practices for SEO continue to be relevant because our generative AI features on Google Search are rooted in our core Search ranking and quality systems."

The same guide lists things you can skip for Google Search. You do not need special AI text files, new markup or Markdown pages, you do not need to chop your content into tiny pieces, and you do not need to rewrite pages just for AI systems. Structured data is not required either, though Google still recommends it as part of normal SEO. Its earlier page, AI features and your website, says there are no additional requirements to appear in AI Overviews or AI Mode, and no need to create new machine-readable files, AI text files or markup.

What matters most, the guide says, is content people find unique, compelling and useful. Google says that will likely influence your presence in generative AI search over the long run more than any other suggestion in it, and it contrasts generic tips with first-hand experience.

Do I have to pick one?

No, and you could not if you tried, because the good practices are the same ones. Some of the overlap is plain site housekeeping:

• A site that search engines can crawl and index, that loads quickly and works on a phone
• Clear headings, so people and machines can tell what each section covers
• Internal links that connect related pages
• Structured data where it fits, which what schema markup is covers in plain language

The rest is about the content itself: direct answers to real customer questions, accurate and consistent business details, and original material that reflects real experience. Those three are where I would start, and the list further down puts them in order. Do all of it well and you have done SEO, AEO and GEO without keeping track of which is which.

Okay, but what does this actually look like on my website?

It looks like ordinary, useful work on pages you already have. Here are three hypothetical examples, not real clients:

• A baker adds a plain "Custom orders" section that answers the questions customers ask most: how ordering works, how much notice is needed, and whether it is pickup or delivery.
• A stylist or spa owner gives each service its own page with what is included, how long it takes and how to book, and makes sure the Google Business Profile lists the same services and hours.
• A contractor writes a page for each kind of job and each area served, with the same business name, phone number and address everywhere they appear.

When it comes to AI tools specifically, I focus on what you control, because you do not control what an AI system says. That comes down to four things:

1. Structured, well-organized content, so each page states clearly what it is about.
2. Consistent facts across the web, meaning your listings, profiles and mentions all agree with your website.
3. Local signals, starting with a complete, accurate Google Business Profile. Google says Business Profiles can help products and services be visible in both AI responses and other Google Search results.
4. Monitoring how you appear. Google Search Console has a Generative AI performance report covering AI Overviews and AI Mode impressions, though it may be unavailable for a site with too few AI feature impressions. Bing Webmaster Tools has an AI Performance report, launched in public preview in February 2026, that shows how often your site is cited in Copilot and Bing AI summaries.

If you want a second set of eyes on all of this, the Website SEO Audit checks the technical basics, on-page SEO, local SEO and AI-search readiness (schema, FAQ structure and entity clarity), then hands you a prioritized fix list. If you would rather have the groundwork done for you, SEO Foundations Setup covers the keyword map, titles, schema markup, Search Console and Bing setup, internal linking and Google Business Profile optimization for up to 10 pages.

Do I need schema markup or an llms.txt file for this?

Probably not as a first step, and neither one is a shortcut. Schema markup is structured data in your page code that tells machines what a page represents. Google says it is not required for its AI features, and I go through when it earns its place in What Is Schema Markup?

An llms.txt file is a proposed convention from Jeremy Howard in 2024, a short reading list of your site written for AI tools. Google says Search does not use it, and I could not find any AI company saying its search relies on it. What Is llms.txt? has the details.

FAQ markup was once pitched as an AEO trick, but Google stopped showing FAQ rich results in Search in May 2026. Real questions and answers on your pages are still useful to readers, so keep writing them.

What should I do first?

Start with the unglamorous basics, in this order:

1. Confirm Google can find your site. Verify it in Search Console and check whether your pages are indexed. Why Your Website Is Not on Google walks through the usual causes.
2. Read your homepage and main service pages like a stranger would. Does the first paragraph say what you do, for whom and where? If not, rewrite it so it does.
3. Make your business details match everywhere: website, Google Business Profile, directories and social profiles. The Google Business Profile checklist is a good place to begin.
4. Turn the questions customers ask you most into headings, with a direct answer under each one. My plain guide to answer engine optimization shows what that looks like.
5. Add something only you can say: how you work, your own photos, what you have learned from doing the job.

None of this replaces the basics: a site that search engines can crawl and index, with content that is useful and original.
