How do marketers get consistent, on-brand outputs with prompting?

Provide a brand voice guide, target persona, and product facts. Specify the channel and constraints (CTA, length, compliance). Include positive and negative examples so tone is unambiguous. Ask for multiple variations and a rationale that maps to the persona’s pain points. Add a final step where the model self-checks against your brand rules before delivering copy.

Next step: AI for marketing, a playbook of seven ChatGPT prompts for launch posts, brand voice, SEO briefs and test results, with real output.
