How to Get Your Brand Cited by ChatGPT and Perplexity (GEO in 2026)

To be cited by ChatGPT, Perplexity, or Google AI Overviews, structure each page so it is the cleanest quotable answer to a question. Answer the question fully in the first 150 words. Add FAQ schema. Publish original data. Earn third-party mentions that name you specifically. That is the entire playbook — the rest is execution.

I built deepap.dev with this in mind from day one, including llms.txt, ai.txt, and FAQ schema on every post. Here is what I know from building it and from shipping AI products that these engines end up summarising.

What GEO is and how it differs from SEO

Generative Engine Optimisation (GEO) is the practice of structuring content so AI systems retrieve and cite it when answering user queries. It is related to SEO but not the same thing.

Traditional SEO optimises for ranking — getting a blue link near the top of a results page. GEO optimises for quotability — getting your content extracted, paraphrased, or cited inside an AI-generated answer. The user may never see your URL. They see your answer, attributed to you if you are lucky, unattributed if you are not.

The underlying mechanics differ too. Search engines rank documents. AI engines compress and synthesise them. A page with a weak opening paragraph but strong domain authority can rank well in traditional search. It will rarely get quoted by an AI engine — those systems pull from the first dense, direct answer they find.

Why it matters now

The reach is real. Google AI Overviews appear in roughly 30-40% of searches. ChatGPT has around 200 million weekly active users. Perplexity processes around 100 million queries per month. That is a substantial share of the information-seeking that used to go purely through search result clicks.

If your brand is not surfacing in these systems, you are invisible to a growing slice of your audience — particularly for the high-intent queries where someone is comparing options, researching a problem, or deciding whether to trust a vendor.

The window to establish early positioning is still open. Most brands have not structured their content for AI citation. That is an advantage you can take now.

The on-page playbook

Answer directly in the first 150 words

AI engines weight the first 150 words of a page heavily. They are looking for a clean, direct answer to a plausible user question. If your opening paragraph is an anecdote, a welcome message, or a preamble about what you will discuss, the engine skips it and goes to the next source.

Write as if someone asked the question and you are answering it, right now, in the first sentence. Then support it. Every post on deepap.dev opens this way.

Structure with clear H2 sections

Section headers that match likely query phrasings help AI engines segment your content into retrievable chunks. "How to do X" and "Why X matters" are better headers than "Our approach" or "Background."

Keep paragraphs short. AI engines extract individual paragraphs, not pages. A dense 400-word block is harder to quote cleanly than four 100-word paragraphs with a clear point each.

Add FAQ schema and actual FAQ sections

FAQs serve two purposes. First, they directly match the question-answer structure that AI engines use for citation. Second, FAQ schema markup (JSON-LD) signals the structure to crawlers unambiguously.

Write FAQs that answer real search queries, not marketing questions. "How much does this cost?" is a real question. "What makes you different?" is not an FAQ — it is a sales pitch formatted as a question.

Publish original data

AI engines prefer sources that contain something no other source has. Original surveys, benchmarks, case study numbers, or even careful first-person observations from practice count. "In my experience building X" is original. A paraphrase of what TechCrunch said is not.

For deepap.dev, the original data is practical — the user count for SmartON, the specific architectural choices in Dhiya NPM, the routing logic in MIRA. That specificity is what gets quoted.

The off-page playbook

Earn third-party citations that name you

AI engines build entity graphs. They know who you are partly from what other sources say about you. If ten credible sites mention "Deep Parmar, CTO at Sunbots Innovations" in the context of assistive AI, the engine builds a cleaner entity record that it can cite with confidence.

Guest posts, podcast mentions, newsletter inclusions, press coverage, and GitHub stars on open-source projects all contribute. The key is that the mention is specific — your name, your product, your claim — not a vague link.

Build your E-E-A-T signals

Google's framework of Experience, Expertise, Authoritativeness, and Trustworthiness applies beyond Google. AI engines synthesise from sources they assess as credible. First-person accounts of real systems ("I built X and here is what I found") score on Experience. Consistent, accurate technical content scores on Expertise. Third-party citations and verified profiles score on Authoritativeness.

Put your real credentials where crawlers can read them — your about page, your bylines, your schema markup.

Add llms.txt and ai.txt

llms.txt is a plain-text file at the root of your domain that tells AI crawlers what your site is about, who you are, and what content is most relevant to cite. It is the robots.txt equivalent for AI engines. I have it on deepap.dev. It takes 20 minutes to write and almost no one has done it yet.

ai.txt serves a similar purpose for AI consent and attribution preferences. Add both.

How to measure AI citation and visibility

Traditional analytics will not tell you whether AI engines are citing you. You need to check directly.

The simplest method: query ChatGPT, Perplexity, and Google AI Overviews for questions your content answers, and note whether your site or name appears in the response. Do this monthly for your 10 most important target queries.

More systematically, tools for tracking AI citation are emerging in 2026 — some SEO platforms now include AI visibility dashboards. These are early and imperfect, but worth monitoring.

Track referral traffic from Perplexity (it passes referrer headers). Monitor brand search volume — if AI engines are citing you well, direct and branded searches tend to increase even when click-through from AI results is low.
