What Is AEO in Marketing? (Plain-English Answer)
- AEO means making your business easy for AI assistants to find, understand, and recommend.
- When someone asks ChatGPT, Perplexity, or Claude a question, those tools now answer from your site, not just from search results.
- You measure AEO by watching which AI crawlers visit your pages, how often, and whether their referrals turn into clicks.
- AEO is not a replacement for SEO. It runs alongside it.
- You can start with a free AI visibility check that reads a public URL and emails you a report.
AEO stands for answer engine optimization. It is the practice of making your website the source an AI assistant picks when someone asks a question. If you run a business that used to rely on Google traffic, you have likely noticed that fewer people are clicking through to individual websites. More often, they get an answer written by an AI, and the answer pulls from sites like yours without you knowing it.
Search engines still matter. But a growing share of discovery starts with a question typed into an AI chat interface. The AI reads a handful of sources, synthesizes an answer, and often includes a link or two. Whether your business gets named in that answer depends on how well AI systems can understand and trust your content. That is what AEO addresses.
How AEO differs from SEO
SEO optimizes for a ranking algorithm. AEO optimizes for a language model that is selecting sources to cite. The two overlap, but the mechanics differ.
| SEO | AEO | |
|---|---|---|
| Primary audience | Search engine crawlers | AI crawlers and assistants |
| Goal | Rank in search results | Get cited or fetched in AI answers |
| Key signals | Keywords, backlinks, page speed, domain authority | Clear structure, factual content, crawlability, cited sources |
| Measurement | Rankings, organic traffic, impressions | AI crawler hits, AI referrals, visibility in answers |
| Timeline | Weeks to months | Still early, but the same content changes help both |
You do not need to choose between them. A site that is well structured for AI is usually well structured for Google too. The difference is in how you track success.
The three types of AI crawlers
To understand AEO in practice, you need to know what actually visits your site. Kymo classifies AI crawler traffic into three categories, and each one means something different for you.
ai_answer crawlers perform a live fetch. When a person asks ChatGPT, Claude, or Perplexity a question, the assistant sometimes goes out and reads your page in real time to craft an answer. These are one-off fetches triggered by a single question. They are the closest thing you have to a signal that your content is being used in an actual answer.
indexing crawlers work like search engine bots. OAI-SearchBot, Claude-SearchBot, and PerplexityBot scan your site to build a knowledge base for future answers. They do not represent an immediate question, but they matter because they determine whether your site is in the pool of sources an AI can draw from.
training crawlers, like GPTBot, ClaudeBot, and CCBot (Common Crawl), collect content at scale to train models. You might not want to block these, because the models trained on public data are the same models that later answer questions about your industry. But the direct traffic value is low.
For more detail on the specific crawlers and their behaviors, see our AI crawlers archive.
What to measure in AEO
You cannot improve what you do not measure. With AEO, there are three numbers that actually matter.
- Crawler activity per page. Which pages are AI assistants fetching? If your pricing page gets fetched often but your service page never does, the AI is finding something useful on one page and not the other.
- Referral clicks from AI answers. When an AI cites you, some readers click through. That traffic shows up as a referral from ChatGPT, Perplexity, or Claude. This is the closest thing to a direct ROI number for AEO.
- Likely prompts behind the fetches. If you can see which pages get fetched and pair that with the context of the referral, you can infer what questions your content is answering.

How to make your site answer-ready
AEO is not about gaming a system. It is about removing friction between your content and the AI that wants to summarize it.
Write direct answers to direct questions. If someone asks "what is aeo in marketing," they want a definition in the first sentence, not after three paragraphs of story. Clear, declarative sentences are easier for AI to quote.
Structure with headings and lists. A page with a clear H1, logical H2s, and bullet points is easier to parse than a wall of text. This is also just good writing.
Keep facts current and cited. AI assistants favor sources that are up to date. If your statistics say "as of 2019," a 2025 model will pick a different source. Cite where your data comes from, and refresh it.
Do not block AI crawlers indiscriminately. You can control them with robots.txt. Google-Extended (a robots.txt control token, not a crawler) gives you separate control over whether Google uses your content for AI training versus search indexing. Think before you block everything; you might be hiding from the very sources that could send you traffic.
For a full run-through of these tactics, the AEO explained section has posts on each of them, and the Small Business Guide to AEO ties it together in one place.
The honest limits of AEO
No tool can guarantee that an AI will cite you. Not Kymo, not anyone. AI assistants choose sources based on their own models and training, and those choices change over time. What you can do is make sure you are visible, measurable, and easy to understand. If an AI decides to cite a source in your niche, you want it to be yours.
AEO also does not fix bad content. If your site has thin pages, outdated information, or a structure that confuses even human readers, no amount of crawler tracking will help. The analytics show you where the problem is. You still have to fix the content.
What AEO costs
You can start with Kymo's free AI visibility checker. It reads a URL from public signals only, so the site does not need Kymo installed, and the report arrives by a magic link over email. It tells you whether AI assistants can reach and understand a given page.
For ongoing measurement, Kymo's paid plans start at $9 a month for the Solo plan, or $90 a year, for up to 10,000 events a month. The Studio plan is $29 a month, or $290 a year, for up to 100,000 events a month. Every feature is included on both plans; the only difference is event volume. Both start with 14 days free, no card required. AI crawler tracking does not count against your event limit, so you can monitor AI activity without consuming your regular analytics quota. If you exceed your event limit, the dashboard pauses but your data is not deleted.
If you are coming from GA4, you will find Kymo simpler. The AI search for small business posts cover how small teams can handle this without an analyst on staff.
AEO in practice
Here is a concrete example. A local plumbing company publishes a page called "How much does a water heater replacement cost in Austin?" The page answers the question directly in the first paragraph, includes a price table, and is updated twice a year.
A few weeks after publishing, Kymo shows three things. PerplexityBot indexes the page. A week later, an ai_answer fetch happens from ChatGPT-User. Then a click arrives from an AI referral. That is the full AEO loop: indexing, fetch, referral. The plumber can now measure which of their pages are doing this and double down on the topics that attract AI attention.
Compare that to a competitor who runs the same business with a generic website filled with stock photography and no clear answers. Their pages might not even be crawlable for AI purposes, and they have no way of knowing. For more context on what is normal in your sector, the Bounce Rate for Small Business Sites: What's Normal post is a useful baseline for the human side of your traffic.
Start measuring your AI visibility
Decide what you want to learn. If you want a one-time snapshot of whether AI can reach your pages, run the free AI visibility checker on your homepage and your highest traffic pages. If you want continuous data on which AI crawlers visit, which pages they fetch, and whether their referrals turn into clicks, start tracking with Kymo.
Both routes lead to the same place, a clear picture of how AI discovers your business. The AEO guide linked above is the practical playbook for the content changes. The analytics tell you whether any of it moved.
