The question the audit answers
Most growth advice is about what you publish. The profile audit starts one step earlier: the page a reader lands on after clicking your name. It reads that page the way a first-time visitor and a search engine read it.
How it scores
Five categories, weighted the way they affect whether a visit turns into a subscriber. The score is deterministic: no AI decides the number, and anything the page does not let the audit measure is excluded rather than guessed.
