What Is SEO for AI Called? AEO, GEO, AIO Explained
- SEO for AI is called AEO (Answer Engine Optimization), GEO (Generative Engine Optimization), or AIO (AI Optimization), depending on which channel you are trying to win.
- AEO focuses on getting cited in an AI answer, GEO focuses on getting recommended by a generative engine, and AIO is the umbrella term for both.
- Each one has a different target: live answer fetchers, training crawlers, and search index crawlers.
- You can measure all of it with the same basic toolkit, UTM links, goal tracking, and crawler logs.
- The names matter less than the action: track which AI systems fetch your pages and what they do with them.
The short answer is that the practice doesn't have one settled name. What is SEO for AI called depends on who is writing the blog post. AEO, answer engine optimization, is the oldest term, focused on getting your business cited in a direct answer. GEO, generative engine optimization, came later and covers being recommended by tools like ChatGPT and Perplexity. AIO, AI optimization, is the catch-all label that includes both. You will hear the terms used interchangeably, so the practical question is what each one actually asks you to do.
AEO: get cited in the answer
AEO is the closest thing to a direct translation of "SEO for AI" into a strategy. It treats AI assistants as a search engine that returns one answer instead of ten blue links. Your goal is to be the source that answer is built from.
The mechanics are familiar. AI assistants pull from pages that are clearly structured, factually dense, and easy to parse. A page with a direct question in the heading and a concise answer in the paragraph below it is more likely to be used than a page that buries the point under promotional copy. This is the same logic behind featured snippets, which is why a lot of AEO advice sounds like old SEO advice.
The difference is the crawler. When someone asks ChatGPT a question, it doesn't always use a cached index. It may send a live fetch. That fetch is made by ChatGPT-User (OpenAI's live fetcher), and it happens in real time. If your server responds quickly with clean content, you are in the answer. If your page is slow or blocks unknown user agents, you are invisible.
We have a guide that covers the specifics if you want the full breakdown: AEO explained.
GEO: get recommended by the engine
GEO is a broader term that came out of research at Princeton and Georgia Tech. It doesn't just target the answer box. It targets the entire generated response, including the narrative, the comparisons, and the citations. A GEO strategy asks how your brand becomes the thing an AI mentions when it summarizes a topic.
That is a different challenge. A live answer fetch might be looking for a single fact. A generative engine building a paragraph needs context, examples, and authority. It is more likely to cite a page that demonstrates topical coverage than a page that answers one query. This is where depth matters more than precision.
If you want to see how the two compare in practice, read our post on GEO vs SEO: What's Different and What Still Works. The short version is that GEO rewards the same fundamentals as SEO: clear structure, genuine expertise, and consistent publishing. It adds a layer of machine readability on top.
AIO: the practical umbrella
AIO is the term people use when they don't want to pick a side. It covers AEO, GEO, and everything else related to AI visibility. It is the most useful word for a solo builder because it describes the outcome rather than the technique.
Under the AIO umbrella, you are doing three things:
- Making pages that AI systems can read and quote
- Making pages that AI systems can find through search index crawlers
- Making pages that send AI visitors to your site when they click through
Here are the three side by side.
| Term | Stands for | What it targets | How you measure it | Who uses the term |
|---|---|---|---|---|
| AEO | Answer Engine Optimization | Being the cited source in a direct answer | Citations, and clicks on them | The oldest and most common label |
| GEO | Generative Engine Optimization | Being named anywhere in a generated response | Brand mentions in AI output | Came from academic research, now common in marketing |
| AIO | AI Optimization | Every path an AI system takes to your content | Referral traffic from AI platforms | The catch-all, used when the channel is unclear |
Each of those goals is tracked differently. AEO is measured by citations in answers. GEO is measured by brand mentions in generated text. AIO is measured by referral traffic from AI platforms. None of these are the same as ranking on page one. A page that never ranks well on Google can still be a primary source for an AI answer.
The three crawler types you actually need to know
The reason this all gets confusing is that different AI systems send different crawlers to your site. They are not interchangeable. Each one has a job.
GPTBot (OpenAI's training crawler) is the one that appears when OpenAI is collecting data to improve its models. It is a bulk crawler. It is not answering a question in real time and it is not looking for a citation. It is reading your whole site to add context to the model.
ClaudeBot (Anthropic's training crawler) does the same job for Claude. It is also a bulk crawler.
Claude-SearchBot (Anthropic's search index crawler) is different. It builds an index that lets Claude retrieve real-time information. This is the crawler that matters when someone expects a current answer, not a training-data answer.
CCBot (Common Crawl) is the foundation. It is a general web crawler that many AI models have used as training data at some point. If you want to know what an AI system has seen, start here.
The distinction matters because blocking one is not the same as blocking all of them. A site that blocks GPTBot still shows up for ChatGPT users, because the system can fall back to the search index. A site that blocks all crawlers with a robots.txt rule gets nothing.

Which one should you optimize for?
If you are a small business, the answer is not either/or. You cannot afford to build three separate strategies. You need one strategy that covers all three, and that strategy is mostly just good publishing.
- Write a clear answer to the question the page targets, within the first 100 words.
- Use proper heading structure so the page has a visible outline.
- Keep facts consistent with what Google and Bing already know about your industry.
- Cite your sources when you make claims.
- Make sure the page loads fast and doesn't block unknown user agents.
That last point is more important than most people realize. A lot of sites block crawlers out of paranoia, then wonder why they never get cited. If your server returns a 403 to a crawler, that crawler does not come back.
The one thing these crawlers all reward is a page that is easy to summarize. If an AI can extract a fact from your page in under a second, you win. If it has to parse a JavaScript-heavy single-page app or a wall of promotional copy, it moves on.
How you measure any of this
You can't improve what you don't measure. The good news is that AI visibility is measurable with the same tools you use for human traffic.
Track AI crawler visits. They show up in your server logs with a user agent you can identify. Track AI referrals. When a ChatGPT user clicks a citation and lands on your site, that visit looks like any other referral. Track conversions. If you have goal tracking set up, you can see whether AI traffic actually converts compared to Google traffic.
Kymo does this in one dashboard alongside normal analytics. The plans are simple. Solo is $9 a month or $90 a year, up to 10,000 events per month. Studio is $29 a month or $290 a year, up to 100,000 events per month. Both include every feature, and AI crawler tracking does not count against your event limit. Both start with 14 days free, no card required.
One thing to watch is your bounce rate. AI referral traffic behaves differently from search traffic. A visitor from Google might browse three pages. A visitor from ChatGPT already read the answer on the AI platform, so they arrive with a specific intent. They either get what they came for and leave, or they dig into your site. A high bounce rate from AI traffic is not automatically a problem. Our guide on Bounce Rate for Small Business Sites: What's Normal explains what numbers actually matter.
There is also a free way to check where you stand. The free AI visibility check reads a URL from public signals only, so the site does not need Kymo installed. The report arrives by a magic link over email. It tells you which AI systems can see you and how they might describe you.
What the terminology means for your next step
Stop worrying about whether to call it AEO, GEO, or AIO. The terminology only matters when you are deciding where to focus. Choose AEO if your primary goal is being the cited source in a direct answer. Choose GEO if you want the engine to recommend you in a longer narrative. Choose AIO if you just want to understand all the ways AI systems find you.
The practical work is the same. Publish pages that answer real questions, make them fast and parseable, and measure what happens. If you want a structured walkthrough of the process, work through The Small Business Guide to AEO. It covers the exact page structure and content decisions that make a site more visible to AI systems.
Go measure it
The fastest way to know if any of this matters for your business is to see which crawlers actually hit your site and which pages they read. Run the free AI visibility check on your homepage to see what the public signals say, or start a Kymo trial to watch the crawlers arrive in real time alongside your human traffic. Either way, you get data instead of guesses.
