Most marketing fails because the writer is talking to "everyone", and everyone is no one. The cure is not three personas, ten personas, or a wall of demographic charts. It is one real customer, named, with a working empathy map, that you can actually picture when you write.
Build it from someone you have already served. Not a fantasy avatar, a real person with a real Tuesday afternoon and a real set of worries. Write to them. The right strangers will recognise themselves and lean in.
For the deep version, including audience research, three-persona segmentation, and the customer journey map, that is Module 3 of Branding Blueprint.
