Freelance ghostwriter
Good for writing capacity. Usually lighter on positioning, distribution and conversion, so you still own the strategy.
In-house hire
Deep context over time, but one person rarely covers positioning, writing, video, funnels and analytics, and ramp-up takes months.
Specialist studio
A team that brings a tested system — positioning, content, distribution and conversion — and is accountable for outcomes rather than post counts.
How to decide
If you already know exactly what you want to be known for, writing help may be enough. If you need the position itself, start with strategy.
