Nobody will publicly follow a divorce lawyer, and the account can still work
Public engagement is the wrong scoreboard for this practice area. The people you want are watching without touching anything.
A parent thinking about filing does not like the post, does not follow the account and does not comment. Any of those puts the subject in front of a spouse, a coworker and a mother-in-law at the same time, and nobody takes that risk to be polite to a law firm.
They save it instead. Or they forward it to one friend in a private message. Or they watch the whole thing, close the app, and look you up by name weeks later with no trace left behind.
So read saves, private shares and direct messages, and treat follower count as close to meaningless. A small following with a steady trickle of saves is an account doing its job. A larger following with none is decoration.
Build for the silent viewer. Assume nobody taps through to the profile, so each clip has to carry who you are, where you practice and how to reach you on its own.
The direct message inbox is the real front door here, and it needs to be answered like a phone line rather than checked on Fridays.
