ChatGPT answers from two sources: its training data and live web browsing (which surfaces citations). You can't influence past training, but you can shape what its browsing finds now. That means being crawlable (don't block the relevant bots), having pages that directly answer real questions, and earning enough presence that your brand is part of the wider conversation.
The practical levers overlap with strong SEO and GEO: lead with a clear, extractable answer, use descriptive headings, add structured data, and keep facts consistent everywhere you appear. Being cited by other trusted sources — and described consistently across the web — builds the entity signals models rely on.
Authority and trust matter as much as wording. The same E-E-A-T qualities that help you rank help a model decide you're safe to quote. Track it by asking ChatGPT your target questions and seeing whether you appear — part of measuring AI visibility.
