Answer engine optimization (AEO) is suddenly everywhere and it’s one of many names for AI search optimization.
You’ll also see terms like GEO, AIO, and LLM visibility used to refer to much the same idea. But this guide will use the most common term AEO here to keep things simple.
The terminology is new, but most of the work is not. AEO is largely an extension of good SEO and good writing: make useful information clear, credible, and easy for AI tools to cite.
What is answer engine optimization (AEO)?
If you’ve heard generative engine optimization (GEO), AI optimization (AIO), or LLM visibility tossed around and felt a step behind, you’re not missing something obvious. The terminology (and the operations behind it) is genuinely still settling.
There isn’t a strong consensus on which term is “correct” yet. You’ll see several names for roughly the same kind of work. The boundaries appear fuzzy, but here’s the simplest way to think about them:
- AI search optimization → umbrella term
- AEO and GEO → two overlapping names for getting into AI answers
- LLM visibility → the result you measure
- AIO → another broad label with no settled definition
AEO describes the practice of making content easier for AI to understand, cite, and recommend in generated answers. This means optimizing content for AI systems’ answers (i.e., SEO for AI search), not traditional search rankings.
What mentions, citations, and recommendations actually mean
In traditional search, visibility means your page appears in the results; a click means someone visits your site from that result.
Being mentioned, cited, or recommended by AI isn’t the same thing, and the difference matters:
- Mentioned: Your brand is part of the conversation.
- Cited: The AI used your content as a source.
- Recommended: The AI suggests your brand as an option for what someone’s looking for.
It’s worth noting that simply showing up in an AI-generated answer isn’t the same as being the option someone ultimately chooses.
A mention can build awareness, a citation can send someone to your site, and a recommendation can influence what they consider next. Each one tells you something different about how your brand is showing up.

Where AI answers get their information
AI tools don’t all cite the same sources, and the mix varies depending on the question, industry, and tool.
Broadly speaking, citations come from three places:
- Company websites: Product pages, blog posts, guides, and documentation. This is good news for smaller brands: your own useful, specific content can be cited directly. Large cross-platform studies find company-operated websites are the biggest source category overall.
- Independent sources: Reviews, comparison articles, news sites, and industry publications. These give AI tools authoritative information about your brand that doesn’t come directly from you.
- Communities and social platforms: Reddit, YouTube, LinkedIn, forums, and other places where people discuss products and brands. These can matter, but which ones matter most changes significantly by topic and AI tool.
It’s also worth resisting the urge to chase this month’s citation winner. Reddit became a popular target for AI search strategies, only for its share of visible ChatGPT Search citations to drop by about 86% in a single week. The drop happened around the same time ChatGPT changed how it searched the web.
The lesson isn’t to avoid Reddit. It’s not to build your AEO strategy around any one platform’s current citation share. Start with useful content you own, then build a genuine presence in the places your audience already trusts.
Where smaller brands can win in AI search
Bigger brands may have an edge in AI search because they’re already talked about across more of the web, not necessarily because they publish more or better content than everyone else.
That existing footprint can give bigger brands a head start. But it doesn’t mean smaller brands are locked out.
Smaller businesses and creators are often closer to the people they actually serve. You know the specific questions your customers ask, the trade-offs they weigh, and the details a generic answer from a household name tends to miss.
That firsthand knowledge can make a focused, specific answer more useful than something broad from a brand everyone’s heard of. Take your customer’s FAQs and address them head-on with highly targeted content.
You don’t need to outpublish a bigger brand. You need to publish the clearest, most useful answer in the space you already know best and give other people good reasons to talk about it.
One question, several decisions
A person might type one question into an AI search tool, but the answer they actually need often depends on several smaller ones.
Take someone asking, “What’s the best website builder for a small bakery?” They’re not just asking about website builders. The AI is also weighing hosting reliability, ecommerce features, pricing, ease of use, and online ordering before it combines all of that into a single answer.
Google calls its version of this query fan-out: AI Mode and AI Overviews can run several related searches behind the scenes and stitch the results into a single response. It’s a useful example of how the process works, not a rule that every AI tool follows the same method.
Google’s query fan-out video shows this process in action:
That matters because a page that only answers the headline question can miss the details people actually need to act on. Answer the main question clearly, then cover the follow-ups that naturally come next — you don’t need to chase down every possible sub-question to be useful.
Those same follow-up questions are useful for content planning, too. Our guide to building an endless stream of content ideas with WordPress and Claude shows one way to work through them.
How AEO compares to SEO
The biggest difference between AEO and SEO comes down to what you’re actually optimizing for.
Traditional SEO focuses on earning clicks from search results. AEO cares about earning mentions and citations in AI-generated answers — so a click isn’t the only outcome that counts anymore. In that sense, AEO builds on SEO instead of replacing it.
The same practices that help people and search engines understand your content also help AI systems cite and recommend it.
Google’s own guidance supports this: established SEO fundamentals still apply to AI Overviews and AI Mode – no separate playbook required.

How to tell if AEO is working
AEO measurement looks different from traditional SEO because there’s a new layer of visibility to track.
Dedicated AI visibility tools like OtterlyAI can show whether your brand is being mentioned or cited across answer engines. That tells you whether you’re showing up in the answer itself.
Traffic tools answer the next question. WordPress.com Stats and Google Analytics can show when those appearances turn into visits to your site and what people do after they arrive.
A no-budget way to track your AEO visibility
However, you don’t need an enterprise tool to start checking whether your AEO work is having an effect.
A spreadsheet and a few repeatable questions can give you a useful baseline. Treat this as a pulse check, not a ranking report.
- Ask the questions your customers ask
Pick five to ten questions that matter to your business and run the same prompts through tools like ChatGPT, Perplexity, Gemini, or Google AI Mode. Note whether your brand appears, whether your site is cited, and which competitors show up instead. Look at what those cited sources offer that yours doesn’t. - Ask AI about your brand directly
Does it describe your business accurately? Does it associate you with the products, services, or topics you want to be known for? If the answer is vague, outdated, or inconsistent across tools, that can point to gaps in how clearly your brand is represented online. - Track the same prompts over time
Record the prompt, platform, date, mentions, and citations in a simple spreadsheet, then check again monthly. If you publish something specifically aimed at one of those questions, record the result before publishing and compare it again later.
Taken together, these signals give you a clearer picture: Are you showing up? Are people clicking through? And is that traffic doing anything useful once it gets there?
AEO is still developing, so the exact metrics and tools will continue to change. Our AI Tools archive rounds up our latest coverage in one place, including our guide to AI discovery and a plain-English look at what’s new in WordPress 7.0’s AI infrastructure.
Prepare your website for AI search with WordPress.com
Most of what people are calling AEO right now is just being clear enough that a machine can quote you. It’s an evolution of good SEO and good writing, not an entirely new discipline.
The fundamentals haven’t changed: create helpful content, structure it clearly, and build credibility both on and beyond your own site. Those habits will continue to put your content in the best position to be discovered.
If you’re ready to put that into practice, follow these 9 steps to prepare your WordPress site for AI search engines.
This is really interesting! I’m still learning about AEO and how AI is changing the way people search for information online. As someone who writes and shares content on WordPress myself, it makes me wonder how these changes will affect bloggers and other content creators, not just businesses and sales.
I’ve been learning more and more about AI lately, and it amazes me how quickly technology continues to change. I’m curious—do you think AEO will eventually become just as important for everyday bloggers and content creators as it is becoming for businesses?
Hi Kamala, great question! AEO can absolutely matter for bloggers and creators too — especially if your goal is helping more people discover your work. The same principle applies: create genuinely useful content, answer the questions your audience actually has, and make those answers easy to understand.
Really liked the point that AEO is less about chasing a new set of “AI ranking tricks” and more about making information genuinely clear and useful. One thing I’d add is that good AEO also starts with understanding the questions behind a search, not just the keywords. If a page answers the main question directly and then covers the practical follow-up questions a reader is likely to have, it becomes much more useful for both people and search systems. The shift from optimizing for phrases to optimizing for understanding is probably the most important part of this conversation.
So tired of AI. So very, very tired. Search engines are worse than they have ever been. I’m offered the “opportunity” to have a prediction engine write my blog for me, then optimize it so that another prediction engine can scan it for useful content to redeploy in summary so that no one has to actually visit my page (which, need I point out, is one of the main reasons for HAVING a page?)
I don’t know about other people, but I’m a writer. I’ve been writing and selling my writing for a quarter of a century. These “advances” not only devalue the work I have done, the effort I have put into improving, the time I have spent trying to promote my work, but they actively make it harder to earn anything from that work.
On the other hand, aside from more than fifty percent of the internet now being nothing but machines gibbering at one another, a bunch of techbros are skimming money from Venture Capitalists, so that’s nice.
I definitely prefer to have the sources cited that Ai is pulling from.
I understand the purpose of AEOS, and how they are supposed to be better than SEOS, but I don’t get it; Your data is getting used without even considering the fact you want to opt out, and when they offer a way to opt out, it is in the most obscure method. I am not a business owner, nor do I really have a website, but I don’t want my sources, my hard work, my data getting stolen and getting simplified into an AI that sometimes doesn’t even have correct information. Thank you for giving me details about what an AEO is, the formatting and design of this blog is great.
Hi! Thanks for raising this — you can prevent your site’s public content from being shared with third parties, including for AI training, under Settings → Reading → Site Visibility → Prevent third-party sharing. We have a step-by-step guide here. That setting also adds known AI crawlers to your site’s robots.txt block list, although individual AI platforms ultimately have to honor it.
And thank you for the kind words about the post itself!
The ‘mentions vs citations vs recommendations’ framing is really useful — it finally gives names to three different jobs AI search does. I’ve been tracking our brand mentions manually in AI Overviews and ChatGPT, and query fan-out makes it tricky since the same question gets phrased so many different ways. One thing that’s worked for us: adding a short TL;DR-style summary at the top of key pages, which seems to get lifted into answers more often. Curious if anyone has seen whether FAQ schema still matters when the answer engine is doing its own synthesis.
Hi Harry, great question! We wouldn’t treat FAQ schema as a shortcut to AEO. Structured data can still help search engines and LLMs understand what a page contains, but it doesn’t guarantee an AI citation. Your TL;DR example is closer to the bigger principle: make the answer genuinely useful and easy to extract first, then use schema where it accurately describes the content.
