The most common personal-brand mistake is talking about a bit of everything. When followers see marketing one week, productivity the next and then travel, they can't link you to anything. Write your position in one sentence:
That sentence also decides what you leave out. A topic that doesn't fit isn't your main account's subject, however much it interests you. This doesn't box you in; it makes the sentence people use when recommending you easier to say.
Don't be afraid of a narrow position. Nobody can recommend an expert who “helps everyone”, because they don't know whom to recommend them to. A narrow position doesn't shrink your audience; it increases the number of people who can describe you to the right person. Your position can widen over time, but in the first year, owning one subject brings more work than being visible in five.
- Write down at most three topics you want to be known for and treat the rest as secondary.
- Rewrite your bio around your positioning sentence: say who you help with what, not your job title.
- Pin a post that explains your subject to someone seeing your profile for the first time.
- Have a friend look at your profile for ten seconds and ask what you do; if the answer is far from your sentence, fix the profile.
