Google states that its AI Overviews and AI Mode carry no additional requirements or special optimizations, and need no new machine readable files or markup, only that a page be indexed and eligible for a snippet. That single line dissolves most of the supposed war between writing for a person and writing for a retrieval system. The properties that make a passage quotable by a machine are mostly the properties that make it useful to a reader: it stands on its own, it keeps its evidence next to its claim, it states the condition under which the claim holds, and it names its subject.
So the working answer is short. Write the piece for the reader, then edit every paragraph as though it will be read alone, because it might be. ChatGPT search turns a question into one or more targeted queries, and the web search tool returns two main response parts, the answer text and the citation annotations attached to it. Your paragraph either survives that trip on its own or it does not, and the edit that makes it survive costs the reader nothing.
Do you have to write differently for humans and AI?
No, and the strongest argument against it is published by the engines. Google's guidance on succeeding in AI search points at the same practices it has recommended for a decade, and its helpful, reliable, people-first content documentation is still the operative standard. There is no second document describing the machine dialect, because there is no machine dialect.
The belief that one exists is a holdover from keyword-era search, when writing for a crawler really did mean degrading prose. That crawler counted strings. The systems reading you now retrieve passages by meaning, then quote them. Degrading the prose degrades the passage.
The evidence on rewriting for machines is worse than neutral. C-SEO Bench, published at NeurIPS 2025, found most rewrite methods largely ineffective and often harmful to citation rank. If a stylistic trick worked reliably, that benchmark would have caught it. Almost none of them did.
What actually makes a passage quotable by a machine?
Four things, and a reader wants all four. Retrieval happens at the level of the passage rather than the page, which is why the mechanics of how AI reads your content matter more than page-level polish. The unit that gets quoted is a chunk of your prose torn out of its neighborhood, so the question for every paragraph is whether it still means something once the neighborhood is gone.
First, self-containment. A paragraph that depends on the previous one to say what it is about will be retrieved without it.
Second, the claim and its evidence in the same span. In the GEO study, adding statistics, quotations or citations beside the claim improved visibility by roughly 30 to 40% on the authors' word-count metric, 41% for the best single method, and the published version carries the same result. A reader who wants to check you needs the same adjacency.
Third, a stated condition. A claim with its scope attached, the sample, the year, the segment it applies to, is a claim a model can quote without hedging and a claim a reader can test. Fourth, a named subject, so a passage lifted on its own still says who it is about. Do not expect naming to lift retrieval by itself: in a 2026 study of 443 entity-oriented retrieval configurations on a news benchmark, entity signals added at most 0.051 MAP once they could not peek at the answers.
None of those four asks you to write badly. They ask you to finish sentences you would otherwise leave the reader to complete from context. That is a craft improvement wearing a technical justification.
Where do the two readers actually conflict?
In three places, and each one deserves a precise name, because the overlap is not total. Each has a resolution, and no linter can enforce any of them.
The first is build-up. A reader will follow four paragraphs of setup toward a conclusion and enjoy the arrival. A retriever may take the setup and leave the conclusion behind, or take the conclusion with none of the reasoning that earned it.
Liu et al. documented positional bias in how language models use long inputs, a second reason not to bury the conclusion. The resolution keeps the build-up and makes the paragraph that lands the conclusion carry a compressed version of the argument, so the extract is honest on its own. The reader gets a summary sentence they can skip; the retriever gets a passage that is not a fragment.
The second is the pronoun. Good prose resolves references across paragraphs, and a reader tracks a subject over a page without effort. A passage-level retriever cannot.
The paragraph that begins with this approach or the company is legible in place and meaningless once lifted. The resolution is to name the subject once per paragraph, usually in the first or second sentence, and then use pronouns freely inside it. Done well this reads as emphasis; done badly it reads as a bot, which is why it is a judgment.
The third is the sentence that exists because it is good. A turn of phrase, a joke, an image carrying no extractable claim. There is no retrieval argument for keeping it and a strong reader argument. Keep it.
The handling is to make sure it is not the only thing a paragraph does. One claim and one flourish serves both audiences, while a paragraph of pure flourish serves one and is invisible to the other.
Why do phrasing tricks fail when plain evidence does not?
Because the tricks operate on the surface and retrieval operates on the match. C-SEO Bench tested conversational-SEO methods across two tasks and six domains, and the paper points instead toward traditional retrieval-side improvements, which is a polite way of saying the boring work still decides it.
Some persuasion language does move the number, in the wrong direction. Scarcity and exclusivity framing measurably reduces how often a model recommends a product, a result measured across three sets of 10 fictitious products. The marketing instinct to add urgency is an active liability in a passage a model is deciding whether to quote.
There is also a floor under all of this that has nothing to do with style. Serving different content to crawlers than to people is cloaking under Google's spam policy, so the literal version of writing-for-machines is a violation as well as a waste. Whatever you publish for the retriever is what your reader gets, which is another reason the two jobs collapse into one.
How do you edit a draft for both readers in one pass?
Read each paragraph out of order, at random, and ask what it is about and how you know. If either answer requires the paragraph above it, fix that paragraph. This is the whole method, and it takes about twenty minutes on a two thousand word piece.
Then check the evidence density. Google's writing guidance runs to 14 recommendations for product reviews, and the pattern they share is specificity: what you measured, what you compared it against, what the limits were. That is what a reader trusts and what a retriever can quote without inventing scope.
Do not expect to A/B test a sentence. A 2026 variance-components study decomposes run-to-run variance in AI visibility measurement, which is why a single before-and-after comparison is not evidence, and the SparkToro research found AI engines highly inconsistent when recommending brands or products across runs.
Two mechanical checks belong in the same pass. Confirm the page renders without JavaScript, because Vercel's crawler research with MERJ documented that major AI crawlers read raw HTML. And treat structured data markup as a description of what is already on the page, never as a substitute for writing it in prose.
Finally, be realistic about where the answer comes from. Ahrefs found 38% of AI Overview citations rank in the organic top 10 across 4 million AI Overview URLs in March 2026, and Profound put more than 4 in 10 AI citations on third-party sources. Your prose decides whether your page is quotable. It does not decide whether your page is the one consulted.
How does Trovance help you write for both readers?
Trovance starts from the evidence. You define the questions your buyers actually ask, and the platform sweeps them across AI engines every week, preserving each answer as a snapshot with its full context: who was mentioned, whose page was cited, and what the engine actually said. Running them once tells you almost nothing, which is the point Search Engine Land's write-up of the recommendation-list research makes at length.
That record is what tells you whether the page you revised last month is the one being cited, or whether a competitor's page is answering your question. From there the work becomes specific.
The Brain keeps the claims you are entitled to make with the proof behind each one, and drafts are written in your voice from your voice guidance and research sources. Recommended actions name what the record says is missing, such as the comparison a cited third-party source makes that your page does not answer. Which sources an engine reaches for is itself a studied question: AirOps' March 2026 analysis of 548,534 pages ChatGPT retrieved found only 15% were cited.
Every draft goes to a person for review before it publishes. The loop closes on the next analysis cycle: after a revision goes live, the same tracked questions run again, and you compare the new answer snapshots against the old ones to see whether the citation moved. That is how you learn which of your editing habits are doing work and which are superstition, which is the part no single-run audit can give you.
What Trovance will not do is promise that a sentence you rewrite will be quoted. No honest system can, because AI engines are inconsistent recommenders across runs and the sources they consult keep changing, which is the problem Ronald Sielinski's Quantifying Uncertainty in AI Visibility sets out to measure. It will not score your visibility as one number, and it will not publish without your approval. What it does is preserve enough evidence that your craft decisions stop being guesses.
What should you do this week?
Take one page that matters and run the out-of-order read on it. Count the paragraphs that cannot say what they are about without their neighbor, and fix those first, because that single habit covers most of the overlap between the two audiences.
Then attach a condition to your three most important claims: the sample, the year, the segment. If you cannot state the condition, the claim is not ready for either reader. The IAB's framework separates presence, prominence, portrayal and persuasion, and prose quality mostly moves the middle two. Knowing which one you are trying to move keeps you from rewriting a page when the real gap is that nobody cites you.
Last, stop treating structure as the achievement. Structure is the floor now, produced by any tool, and the thing that separates two structurally identical pages is whether one of them knows something. If you want to see which of your pages are actually being cited before you rewrite anything, start a free Trovance trial and read the answer runs first.
