ad writer; adman
A person who writes advertising copy; a somewhat dated term, often replaced by コピーライター in modern contexts.

Variant spelling with a middle dot, sometimes used to clarify the word boundary.
コピーライター is the more common modern term for a copywriter, while アドライター is an older loanword that may sound dated.
