How AI assistants decide what to cite, the nine things worth doing, and the honest list of what does not work yet.

THE SHORT ANSWER To get cited by AI assistants, publish content that answers a specific question completely in a self-contained block of 40 to 80 words, positioned high on the page, with concrete figures rather than vague ranges. Use question-shaped headings that match how people actually ask. Add FAQPage and How To schema. Keep your entity information — name, address, credentials, descriptions — consistent everywhere it appears online. And check that your robots.txt is not blocking AI crawlers, which is the most common reason a site is invisible to AI search entirely. Most importantly: AEO does not replace SEO. Most AI systems retrieve from search indexes, so ranking well in traditional search remains the largest single factor in whether you get cited at all.

A meaningful share of the questions your customers used to type into Google are now being asked in a chat window. They are not scrolling ten blue links; they are getting one answer, sometimes with a couple of citations underneath.

Which raises an obvious commercial question: how do you become one of those citations?

There is a great deal being sold as the answer right now, and a fair amount of it is repackaged SEO advice with new labels. This guide separates what is genuinely working from what is speculation — including a section on the things that do not work yet, because knowing where not to spend is worth as much as knowing where to.

What is answer engine optimization?

Answer engine optimization, or AEO, is the practice of structuring content so that AI assistants can find it, understand it, and cite it when answering a user’s question. It is sometimes called generative engine optimization, or GEO. The terms are used interchangeably and describe the same work.

The distinction from traditional SEO is the goal. Classic SEO optimises for a ranking position that earns a click. AEO optimises for being the source an assistant draws on — which may or may not produce a click, but does produce something arguably more valuable: your brand named as the authority in a direct answer to a purchase-stage question.

Why it matters commercially

When someone asks an assistant to recommend an approach, compare options, or explain what something costs, the sources named in that answer carry unusual weight. There is no results page to scan, no competing listings, no ads above you. Being cited is closer to a referral than to a search result.

That is the opportunity, and it is temporarily larger for smaller sites than classic search ever was, because AI systems select heavily for clarity and specificity rather than for domain authority alone.

How AI assistants decide what to cite

Different systems work differently, and the details change frequently. But the broad mechanics are consistent enough to plan around.

Some assistants answer from what they learned during training. Others retrieve live results from a search index and summarise them. Most now do some combination, and the ones that matter commercially — the ones people ask buying questions — lean heavily on retrieval.

That last point has a consequence people miss: if your content cannot be found by a search index, it usually cannot be cited by the assistant either. AEO sits on top of SEO. It does not replace it.

What Gets Cited	Why
Self-contained answers	A paragraph that makes sense lifted out of context can be quoted; one that depends on the previous three paragraphs cannot
Specific figures and dates	“$4,500 to $6,500 per month in 2026” is citable. “Costs vary considerably” is not
Question-shaped headings	They match the phrasing of the query, making the relevant section easy to locate
Structured data	Schema tells the system what a block of text is, rather than leaving it to infer
Consistent entity information	A business described identically everywhere is easier to identify confidently
Corroboration across sources	Claims repeated by multiple independent sources are treated as more reliable
Recency signals	For anything time-sensitive, a visibly updated page beats an older one
Stated limitations	Content acknowledging what a thing is not good for reads as more trustworthy than one-sided content

Nine things that actually work

01  Put a direct answer near the top

Immediately after the H1, include a 40 to 80 word block that fully answers the question the page targets. Write it so it survives being lifted out of context — no “as mentioned above”, no pronouns referring to earlier text. This single change does more than anything else on this list, and almost nobody does it because it feels like giving away the answer before the article starts. That is exactly why it works.

02  Write headings as questions

“How much does X cost?” outperforms “Pricing”. “What is the difference between X and Y?” outperforms “Comparison”. Phrase headings the way a person would say them out loud, because that is increasingly how queries arrive. Each question-heading section should then answer that question completely within itself.

03  Replace vague ranges with specific numbers

The most common weakness in business content is hedging. “Prices vary depending on your needs” is unciteable by design. A real figure with a date and a source attached is what gets pulled into an answer. If you genuinely cannot publish exact pricing, publish a structured range with the factors that move it — that is still specific enough to cite.

04  Implement schema properly

FAQPage on every page with a question section. HowTo on any process content. Article with a genuine dateModified. Organization with sameAs links to your verified profiles. LocalBusiness where relevant. Schema does not guarantee citation, but it removes ambiguity about what your content is, and ambiguity is what gets a page skipped.

05  Make your entity information identical everywhere

Your business name, description, address, credentials and service list should match across your site, your Google Business Profile, LinkedIn, industry directories and any listings. AI systems build a picture of who you are by aggregating these. Inconsistencies produce a lower-confidence picture, and low confidence means fewer citations.

06  Get mentioned in places assistants already read

Retrieval-based systems draw disproportionately on sources they treat as reliable — established industry publications, well-moderated community forums, review platforms, and reference sites. A single mention in a trade publication your industry actually reads is worth more for AI visibility than a dozen low-quality backlinks.

07  Publish something nobody else has

Original data is the strongest AEO asset available. Real pricing from completed projects, a survey of your own clients, timelines from actual delivery. When an assistant needs a figure and only one source has published it, that source gets cited every time the question comes up. This is the single most durable advantage on this list, because competitors cannot copy data they do not have.

08  Keep pages visibly current

For anything with a year, a price, or a regulation in it, update the page and update the dateModified. Assistants weight freshness heavily on time-sensitive topics, and a page last modified two years ago will lose to a thinner page updated last month.

09  State limitations honestly

Content that says who a service is not right for, or where a cheaper alternative genuinely wins, gets cited noticeably more than one-sided marketing copy. Assistants are built to prefer balanced sources. This is the rare case where the commercially uncomfortable choice is also the technically optimal one.

THE PATTERN UNDERNEATH ALL NINE Every one of these makes your content easier to quote accurately. That is the whole discipline. If you are unsure whether something will help, ask whether it makes a specific claim easier for a machine to lift out and attribute correctly — if yes, do it.

The robots.txt mistake that makes you invisible

This deserves its own section because it silently undoes everything else.

AI companies operate their own crawlers, separate from Googlebot. If your robots.txt blocks them, your content cannot be retrieved and cited, no matter how well optimised it is. A number of sites blocked these crawlers during the period when the default advice was to keep AI systems out, and never revisited the decision.

Check your robots.txt for directives targeting AI user agents — the crawler names used by the major assistant providers and search-adjacent AI products. If you want to be cited, those need to be allowed.

There is a genuine trade-off here and it should be a deliberate decision rather than a default. Allowing AI crawlers means your content may be summarised without a click. Blocking them means you are absent from an increasingly important discovery channel. For most service businesses, being cited and named is worth more than the traffic lost — but a publisher whose revenue depends on page views may reasonably decide otherwise.

What does not work yet

Being direct about this matters, because there is a lot being sold in this space on very little evidence.

• There is no way to guarantee a citation — there is no equivalent of a ranking algorithm you can reverse-engineer. Anyone offering a guaranteed position in AI answers is describing something that does not exist.
• Emerging standards are unproven — llms.txt and similar proposals are interesting and not yet widely adopted or confirmed to influence citation. Adding one costs nothing; building a strategy around it is premature.
• Keyword-stuffing questions does not work — stuffing a page with question headings and no substance behind them produces content that reads badly and gets cited less, not more. The clarity is the point, not the format.
• Publishing volume alone does not build authority — assistants weight corroboration across sources, so claims that appear nowhere else are treated with less confidence, not more.
• Measurement is genuinely immature — tools reporting AI visibility are early and vary considerably in method. Treat their numbers as directional signals, not measurements.

The honest summary is that a large part of AEO is doing well-established things properly: clear writing, specific claims, correct structured data, consistent business information, and content people want to cite. The genuinely new parts are crawler access and the shift toward being quoted rather than clicked.

How to measure it

Imperfectly, but not uselessly. Four things worth tracking:

• Referral traffic from AI assistants — visits arriving from assistant domains appear in analytics and are the clearest direct evidence you are being cited.
• Manual citation checks — periodically ask the major assistants the questions your customers ask, and record whether you appear. It is manual and it is the most reliable signal available.
• Brand mentions — track whether your business name appears in AI answers about your category, even without a link. Being named still drives searches.
• Search Console impressions versus clicks — if AI answers are reducing clicks on informational queries, impressions may hold while clicks decline. That pattern is itself information.

Set a baseline now by running twenty questions your customers actually ask through the major assistants and recording what comes back. In three months, run the same twenty. That comparison will tell you more than any tool currently on the market.

Frequently asked questions

How do I get my website cited by ChatGPT?

Publish self-contained answers of 40 to 80 words near the top of each page, use question-shaped headings, include specific figures and dates rather than vague ranges, implement FAQPage and HowTo schema, keep your business information consistent across the web, and confirm your robots.txt is not blocking AI crawlers. Because most assistants retrieve from search indexes, ranking well in traditional search remains the largest single factor.

What is answer engine optimization?

Answer engine optimization (AEO), also called generative engine optimization (GEO), is the practice of structuring content so AI assistants can find, understand and cite it when answering questions. It differs from traditional SEO in its goal: rather than earning a ranking position and a click, it aims to make your content the source an assistant draw on when producing a direct answer.

Is AEO different from SEO?

It is an extension rather than a replacement. Most AI assistants retrieve from search indexes, so content that cannot be found in traditional search generally cannot be cited either. What AEO adds is optimising for extraction and attribution rather than clicks — self-contained answers, specific figures, structured data, and consistent entity information. The foundation is still SEO.

Should I block AI crawlers in robots.txt?

Only if you have decided you do not want to be cited. Blocking AI crawlers makes your content unavailable for retrieval, which removes you from AI search entirely. For most service businesses, being named as a source in a direct answer is worth more than the traffic lost to summarisation. Publishers whose revenue depends on page views may reasonably reach the opposite conclusion — the point is to decide deliberately rather than by default.

How long does it take to see results from AEO?

Expect two to four months for new content to be indexed, retrieved and begin appearing in AI answers, assuming the page also performs in traditional search. Technical changes such as fixing crawler access or adding schema can have effect sooner. Establishing consistent citation across a category typically takes longer and depends heavily on whether you publish anything genuinely original.

Can you guarantee my site will be cited by AI assistants?

No, and nobody can. There is no ranking position to buy or reverse-engineer, citation behaviour varies between assistants and changes frequently, and measurement tooling is still immature. What can be done is making a site materially more likely to be cited — clearer answers, specific data, correct structured markup, crawler access, and consistent entity information. Any provider promising guaranteed AI rankings is describing something that does not exist.
