What ChatGPT is doing when someone asks for an accountant
The question is almost never accountant near me. It is a situation: I run a two person company, I have not filed since last year, somebody told me I should have elected S corp status, who do I call. The assistant replies with a paragraph and a short list of firms by name.
To write that paragraph it needs facts it can state plainly: what you do, where you are, how you charge, what credential you hold and whether other people say the work went well. When it cannot find them, it names a firm where it can.
That makes this a legibility contest rather than a popularity one. The firm that is easiest to describe correctly is the firm that gets described.
