The Anatomy of a Marketing Prompt: Audience, Goal, Format, Voice, Constraints

This episode teaches the job of prompting, tool-agnostic across whatever the current ChatGPT, Claude, or Gemini happens to be. The central idea: a prompt is a brief, the same brief you'd hand a freelancer or a new junior hire. Anthropic's docs frame the model as "a brilliant but new employee who lacks context on your norms and workflows." Vague brief in, generic slop out. Specific brief in, on-brand draft out.

The five-part anatomy:

  • Audience — exactly who reads it: role, knowledge level, priorities, funnel stage, objections. Paste your ideal customer profile (ICP) or buyer persona. OpenAI notes specifying role and audience gives the most relevant results.
  • Goal — one job-to-be-done, one action, plus success criteria. One goal per prompt.
  • Format — the container: structure, exact length, channel limits (email subject ~50 chars, Google ad headline 30, meta description ~155, X post 280). Tell it what to do, not what not to do.
  • Voice — how it sounds. Show, don't tell: paste examples, don't list adjectives.
  • Constraints — hard limits, must-includes, banned phrases, factual grounding (write [TK] rather than inventing numbers).

The highest-leverage move is few-shot (multishot) prompting: 3-5 of your real past pieces that performed, labeled and diverse. Anthropic recommends examples that are relevant, diverse, and structured.

The one pitfall: slop, the 2025 Word of the Year (Merriam-Webster and the American Dialect Society). With no constraints, the model returns the statistical middle of everything it's seen. The diagnostic: if you can swap your company name for a competitor's and the copy still fits, it's slop.

Mnemonics covered (all repackagings of role + task + context + format + examples): RTF, RACE, CRISPE, RODES, TRIM. Copywriting frameworks for the copy itself: AIDA, PAS, BAB. Common mistakes and fixes, plus a reusable skeleton to save and reuse per channel.
