Most "AI SEO" advice on the internet treats ChatGPT, Google AI Overviews, Gemini, and Perplexity as the same problem. They are not. The mechanics overlap, but each engine has its own data sources, its own citation behavior, and its own quirks. This piece is specifically about ChatGPT — the one most of your customers actually use when they ask an AI for a recommendation.
What ChatGPT search actually is
When someone types a question into ChatGPT, one of two things happens. For questions that can be answered from training data — historical facts, definitions, well-known concepts — ChatGPT answers from what it already knows, with no citations. For questions about current information, specific businesses, recommendations, recent events, or anything where freshness matters, ChatGPT triggers a web search and synthesizes an answer from live sources, with citations linking back to the original pages.
The second case is the one that matters for small businesses. When a potential customer types "best pediatric dentist in St. Petersburg" or "who builds Shopify sites for skincare brands in Florida", ChatGPT runs a search. Whoever gets cited in that answer gets the click — and increasingly, gets the customer.
ChatGPT searches the live web for anything current. The citations are the click.
Where ChatGPT's information actually comes from
Three sources, in rough order of weight for current-information queries.
Bing's search index. ChatGPT search is powered partly by Bing — when ChatGPT runs a web query, Bing is one of the systems returning candidate results. This matters because Bing's rankings are very different from Google's, and Bing rankings are significantly easier to influence. Most small businesses have effectively no Bing optimization in place; the businesses that do have an outsized advantage in ChatGPT citation.
OpenAI's own crawling infrastructure. GPTBot and ChatGPT-User are OpenAI's web crawlers. They fetch pages directly from the open web to verify and supplement what comes back through search. If your robots.txt blocks them — accidentally or via a security plugin that "blocks all bots" — you become uncitable. This is the single most common technical reason small businesses don't appear in ChatGPT answers.
Structured, citable data sources. Pages with FAQ schema, HowTo schema, clear author/organization markup, and clean structural HTML are preferentially cited over pages where the same information is buried in marketing prose. ChatGPT is a language model — it extracts whatever is easiest to extract, and structured data is easiest.
What gets a page cited
Citations in ChatGPT search are not random. They reward specific patterns. Five things that genuinely matter, in order of leverage:
Lever 01
Direct answers to the actual question.
Pages structured around specific questions, with the answer in the first sentence after the question, are heavily favored. A page titled "How long does Botox last?" with the first line "Botox typically lasts three to four months for most patients" will be cited over a page that buries the same answer in paragraph six of a generic "Everything you need to know about Botox" article.
Why: language models extract the cleanest, clearest answer. Burying it makes you uncitable.
Lever 02
GPTBot and ChatGPT-User explicitly allowed.
Open your robots.txt. Make sure neither GPTBot nor ChatGPT-User is blocked. If you're not sure how to check, the file usually lives at yourdomain.com/robots.txt — visit that URL in a browser and look for any Disallow line that mentions either bot. Many WordPress security plugins block them by default.
Why: if you're blocked, nothing else matters.
Lever 03
FAQ schema with substantive answers.
FAQPage structured data is the highest-leverage schema for ChatGPT citation. Each question becomes a discrete unit the model can extract and quote. Aim for 5–8 real questions per page, with answers of 40–80 words each. Don't pad the answers, but don't make them so short they look thin.
Why: FAQ schema is the format ChatGPT prefers to quote.
Lever 04
Entity authority across the open web.
ChatGPT triangulates: when it sees your business mentioned by name on multiple independent sources (your site, your Google Business Profile, local press, industry directories, podcast interviews, partner sites), it builds confidence that the business is real and worth citing. A site with zero outside mentions is treated with much less confidence than one with ten — even if both have the same on-page content.
Why: language models distrust isolated claims. Distributed presence builds citability.
Lever 05
Bing rankings, not just Google.
Most local businesses have a Google strategy and no Bing strategy. The competitive density on Bing is far lower than on Google for the same queries — meaning the same on-page work that gets you to position 40 on Google can land you in the top 5 on Bing. Bing also explicitly feeds ChatGPT search, so a Bing top-5 position is a much more direct path to ChatGPT citation than a Google top-10 position is.
Why: Bing is the underused leverage point. Optimize for it.
What doesn't work
A few patterns the AI SEO industry sells that don't actually move the needle in ChatGPT specifically.
Keyword stuffing in meta descriptions. ChatGPT doesn't read meta descriptions the way Google does for ranking; it reads the body content. Stuffing keywords there is wasted effort.
"AI-optimized" tools that auto-generate question-answer pairs. The output reads like AI slop, and ChatGPT is increasingly good at down-weighting content that looks like other AI wrote it. Original answers in your actual voice perform measurably better.
Pages that exist only to chase AI traffic. Thin pages built specifically to capture AI citations — without real depth, without connection to your actual business — get filtered. ChatGPT rewards pages that read like they were written by humans who know the subject, not by SEO operators trying to game the system.
How to check if it's working
The fastest test: open ChatGPT, type the queries your customers would type ("best [your category] in [your city]", "who does [your service] near [your area]", "[your service] for [your customer type]"), and see whether your business is mentioned. If it isn't, look at which sites are being cited. Read their pages. Notice what they're doing structurally that yours isn't.
Repeat the test every two weeks. Citation patterns shift as ChatGPT updates its underlying systems, so a one-time check isn't enough. Treating ChatGPT search as a living monitoring discipline — not a one-time optimization project — is what separates the businesses that compound their visibility from those that fall back behind.
