This supports referral rather than replacing it
The realistic function is confirming a decision somebody has already been nudged toward, not generating one.
Accounting work arrives through recommendation, from clients, from attorneys and bankers, and from people who have worked with the firm before. Social is not where that starts.
It is frequently where it gets checked. Somebody given a name looks the firm up, and a professional deciding where to send a client wants to see something current and competent.
That sets a modest and achievable objective: be findable, look active, and demonstrate that you understand the kind of work you claim to do.
It also means volume is beside the point. A small following made up of the right professionals and clients is worth more than a large one, and the metrics will never make that case.
Consistency matters more than reach. An account that posts reliably reads as a functioning firm; one that stopped eighteen months ago raises a question the visitor did not have before.
