AEO (answer engine optimization), GEO and AI SEO are the same work

AEO (answer engine optimization), GEO (generative engine optimization) and AI SEO are three names for one job: getting your business named and cited when someone asks an AI tool a question. The names come from different corners of the industry, but the work behind them is the same, and most of it builds on the SEO your site may already have.

Marketers, researchers and agencies each named the same work

Each name describes the same goal from a different starting point.

• AEO (answer engine optimization) is the oldest of the three. It grew up around voice assistants and the answer boxes Google shows above its results, then came back into wide use once ChatGPT, Perplexity and Google's AI Overviews started answering questions directly. An answer engine is any tool that hands you an answer instead of a list of links.
• GEO (generative engine optimization) comes from research. A 2023 paper by researchers at Princeton and partner institutions coined the term while studying how AI tools that write their own answers, which they called generative engines, decide which sources to cite.
• AI SEO is the SEO industry's label. Agencies that already sold search engine optimization added "AI" to describe the same craft applied to AI answers.

The names split because marketers, researchers and SEO agencies met the same change at once and each named it from where they stood. You'll see all three, sometimes on the same page. We call it AI search optimization, because it describes the outcome in the words most business owners already use.

AI tools name businesses they can read and verify

Classic SEO (search engine optimization) works to rank a page in a list. Someone types "renovation contractor Oakville", Google shows a page of results, and the aim is to sit near the top so they click you.

AEO (answer engine optimization) works to make you the business an AI names in its answer. The same person now asks ChatGPT, "Who do people hire for a basement renovation in Oakville?" They get one reply with two or three names, and they may never see a list of links at all.

That shift changes what carries weight:

• Plain statements. An AI tool needs to read, in ordinary words, what you do, who you serve and where. A clever tagline without those details gives it nothing to repeat.
• Direct answers. Pages that answer buyer questions about cost, timelines and the kinds of jobs you take give the AI something it can quote.
• Consistent details across the web. AI tools check your site against your Google Business Profile, directories and LinkedIn. When your name, location and description match, you look reliable. When they differ, you can look like two separate businesses.
• Listings and reviews. Real reviews on the profiles people check help an AI decide you're an established business worth naming.

Your SEO foundations already do most of the work

The foundations of good SEO still do most of the lifting. A fast site, clear pages with one topic each, real headings, and structured data that labels your business, services and location help Google rank you and help AI tools read you. If you've already invested in SEO, that work carries straight over. If you haven't, the same work pays off in both places at once.

Judge providers by their work list, whatever the label

For anyone hiring help, the names are interchangeable. People who say AI SEO usually mean the same thing as GEO (generative engine optimization) and AEO (answer engine optimization). Researchers tend to say GEO, SEO agencies tend to say AI SEO, and many marketers say AEO.

If a provider tells you one of these is a separate service, ask them to show you what they would do differently. In our experience, the list of work comes out the same.

Some offers are relabelled SEO, but the shift is real

The labels are new, and some providers are reselling ordinary SEO retainers under them. The change underneath is real, though. More people ask an AI tool who to hire, and those tools answer with a few names rather than a page of links. You can see it for yourself by asking ChatGPT about your own line of work.

A page can also rank well on Google and still be passed over in an AI answer if it never says plainly what the business does and where. Closing that gap is the work.

Invest when buyers ask AI, fix the basics before then

It's worth it when your customers already ask AI tools who to hire in your category. Contractors are a good example. A homeowner in Oakville might ask ChatGPT who people hire for a basement renovation or a new deck, and the businesses in that reply are the ones who get the call. For a firm like Robsway Contracting, a renovation and framing contractor whose site we built, that question is where a new job can start.

It's also worth it in a category where the AI answer names nobody local yet. The clearest, best-described business in that lane has the best shot at becoming the name the AI repeats.

It can wait when your buyers mostly find you through referrals and a quick Google search, and your site has bigger problems: slow pages, no clear statement of what you do, or nothing a visitor can act on. Fix those first. Those fixes count toward AI search later, so starting there loses nothing.

One caution applies either way. Nobody controls what an AI says, and anyone promising a date or a guaranteed mention is guessing. What you can control is how clearly and consistently your business is described, on your site and across the web.

One ChatGPT question shows where you stand

Two quick ways to find out today:

1. Run the ChatGPT test on our AI search optimization page. Ask what a customer would ask, such as "Who's a good [what you do] in [your city]?", and note who gets named.
2. Read Will AI recommend your business?, our plain-English guide to the five steps that make a business easy for AI tools to recommend.

If a competitor is named instead of you, that's fixable.
