Domain names and AI search: what ChatGPT can and can't change

A good domain name matters more in AI search than it did in the ten blue links, but the evidence for why is thinner than most domain sellers would like. Start with what's solid. OpenAI launched ChatGPT search on 31 October 2024, and its answers include links to the web sources behind them, which users open from a Sources button below the reply. So the domain is on screen at the moment someone decides whether to click. An address that looks plain and established is easier to trust than one that looks improvised, though that part is our view, not a measured result.

Now the figures. In a study published on 26 May 2025, Ahrefs looked at about 75,000 brands and compared a range of factors against how often each brand appeared in Google's AI Overviews. Branded web mentions had the strongest correlation, at 0.664. Backlinks came in at 0.218. Ahrefs says plainly that correlation isn't causation, and we'd say the same. Even so, if AI systems tend to surface the brands people name most often, a name that's easy to remember, spell and say aloud is doing real work.

What we can't tell you is whether a particular extension, or an exact-match name, makes an assistant more likely to cite you. A write-up from the registrar Dynadot, which has an obvious interest in selling domains, reports an Otterly.AI study of more than one million cited URLs in which .com, .org, .io and .ai each averaged 1.7 citations. The same piece says no published study measures how AI systems tie a brand name to a domain. Treat any seller who promises otherwise with suspicion. That includes us, in principle.

So where does that leave a buyer? The practical case is simple. Assistants name businesses in their answers, and the next step is often a person typing or saying that name. The shorter and clearer it is, the more of those people arrive. A name that needs spelling out loses some of them in conversation, and a name that matches the company and its social handles leaves less to piece together for anyone, or anything, working out who the business is.

Dynadot's author makes a similar argument for a registered domain acting as an anchor for a brand, and labels it as reasoning rather than a finding. That seems about right to us.

Our stance is to buy a name for the people who'll say it and type it, and to treat any AI benefit as a bonus you can't yet measure. Content still decides what gets quoted. A strong name on an empty site gives an assistant nothing to cite.
