A niche of a niche of a niche
In most professions, specificity matters.
It helps you define who you serving and what it’s for, just as well as it helps you compete in a crowded space.
It’s easier to be a pediatrician than a general physician (because it narrows the scope of the things you need to know to do your job well). It’s even easier to be a pediatrician, in a small town in Iowa, who specializes in the management of asthma and allergic conditions (because you’re competing in an even smaller space).
For writers, designers, and marketers, especially, specificity helps you do your job even better. Writing, designing, or marketing for your readers, users, or customers is how to effectively differentiate your deliverables enough to ensure they’re actually read, seen, or shared.
It even makes it easier for people to find you online. A “bridal boutique near Daytona,” for example, is a lot easier to tell apart (and to rank for) than a “clothier anywhere in the sunshine state.”
The point is, being ultra-specific often pays for itself in long-term value. Making it easier to draw a crowd around whatever it is you happen to be doing.
