BuildRocket LabsWhat is AEO (answer engine optimization)?
AEO — answer engine optimization — is the practice of getting your business named and cited inside the answers that ChatGPT, Gemini, Claude, Perplexity and Google's AI Overviews write, rather than ranked in a list of blue links below them. It is mostly an editorial discipline, not a technical one: the peer-reviewed research finds that adding quotations, statistics and cited sources to a page moves its visibility in generated answers far more than any markup you can add.
The distinction matters because the two jobs have come apart. A page can rank well and never be cited, or be cited constantly without ranking at all.
Below is what the evidence actually supports, including the parts that contradict what most agencies currently sell.
[ published 2026-07-26 · updated 2026-07-26 ]What actually makes a page more likely to be cited?
The strongest evidence comes from a peer-reviewed study presented at KDD 2024, which tested nine content changes across 10,000 queries and 25 domains and measured how each one moved visibility in generated answers.
The ranking is unambiguous, and it rewards rigour rather than trickery. Keyword stuffing — still standard practice in a lot of SEO work — measurably made pages less visible.
| what you change | visibility change | what it means in practice |
|---|---|---|
| Adding quotations | +41% | Quote named people and documents directly, in their words |
| Adding statistics | +33% | Replace adjectives with numbers you can attribute |
| Improving fluency | +29% | Clear, direct prose beats padded prose |
| Citing sources | +28% | Name and link where every claim came from |
| Sounding authoritative | +12% | Confident, specific claims — not hedged mush |
| Keyword stuffing | −9% | Actively harmful. The old reflex now costs you |
Do I need llms.txt or special schema markup for AEO?
No, on current evidence. Google's own documentation states: "You don't need to create new machine readable files, AI text files, markup, or Markdown to appear in Google Search (including its generative AI capabilities), as Google Search itself doesn't use them," and separately that "structured data isn't required for generative AI search."
A controlled study of 1,885 pages that added JSON-LD schema, matched against roughly 4,000 control pages, found no meaningful citation gain on any major AI surface. A study of around 300,000 domains found no relationship between having an llms.txt file and how often a domain gets cited.
Both are still worth having for other reasons — schema drives rich results and helps machines resolve who you are — but neither is an AI-citation lever, and you should be suspicious of anyone selling them as one.
Is AEO the same as being findable by AI browsing agents?
Related, but not identical. Citation is about being quoted in an answer; agent-readability is about whether software sent by a customer can actually use your site — read your prices, find your booking link, submit your form.
Agents read the accessibility tree, the same structure screen readers have used for twenty years. Sites built from unlabelled div elements and content that only appears after JavaScript runs give an agent nothing to work with.
This is no longer a fringe audience: Cloudflare's network data shows automated clients now account for the majority of requests for HTML. This half of the work is unglamorous and entirely testable, which is why we treat it as engineering rather than marketing.
How do you know whether AEO is working?
By running the same set of buying-intent questions through each engine on a fixed schedule and recording whether you were cited, and who was cited instead. Citation rate is the metric; there is no rank tracker for this yet.
The second signal is referral traffic. AI assistants pass a referrer, so visits from them can be separated from organic search and measured on their own conversion rate.
Related questions
q01Is AEO just a rebrand of SEO?
No, though it overlaps. The technical hygiene is shared — a page still has to be crawlable and indexed. What differs is the target: SEO competes for a position in a list, AEO competes to be the sentence the model writes. The measured levers are different enough that keyword stuffing helps one and hurts the other.
q02How long does AEO take to show results?
Slower than paid ads, faster than traditional SEO in our experience, and genuinely variable. Engines re-crawl and re-rank on their own schedules, and the strongest single signal — being mentioned on sources they already trust — is earned over months rather than switched on.
q03Can I do AEO myself?
Much of it, yes. Answer the questions your customers actually ask, put the answer in the first two sentences, use real numbers, name your sources, keep the pages current, and make sure your site works without JavaScript. That is most of the job, and none of it requires an agency.
