How do I know whether AI can understand my website?
You can't know for certain, no one outside the AI companies themselves can, but you can check the underlying things every AI tool needs to work with in the first place: clear structure, accurate details as real text, and content that actually answers the questions people ask.
That's a genuinely checkable, practical question, even though "will ChatGPT mention me" isn't.
What "understanding" actually means here
It's not about the website being clever or persuasive. It's about whether the basic facts, what the business does, where it operates, how to contact it, are sitting on the page in a form a machine can reliably pick up: real text, not just an image or a logo, plus structured data that spells the same facts out explicitly.
The things worth checking
In practice this comes down to a fairly short, checkable list: heading structure and page titles, schema markup, whether the business name, address and phone appear as visible text, whether there's any question-and-answer style content, whether the site is reachable by crawlers at all, and whether it loads properly on a phone.
None of that is a secret ranking factor. It's the same basic groundwork search engines have rewarded for years, and it happens to be exactly what a language model needs too.
The fastest way to actually check it
Rather than guessing page by page, the free Once-Over runs a real site through that exact list and gives a plain-English readout of what's solid and what's not, in about a minute, with nothing to sign up for.
It only tells you what it actually measured, not a guess at whether ChatGPT will name you specifically.
