AI Marketing Agency Prompt System — Onboarding to Reporting Workflows (ChatGPT, Claude & Gemini)

Our AI Prompt Pack for Social Media Managers gives you 30 quick prompts to grab when you need one caption or one reply. This is the tier above it, and it is built for the agency rather than the channel. Seven end-to-end workflows, each a CHAIN of prompts that carries one client brief from the first paste to a finished deliverable, and each chain ending in a REVIEW step that names exactly what to verify before anything reaches the client. Page 1 distills published prompt-engineering practice into seven rules for agency work. Then the workflows: new-client onboarding and discovery (an 18-question discovery questionnaire, a brand and voice brief built from their answers and their approved work, a 60-minute kickoff agenda); strategy and positioning (an audience and offer analysis from data the CLIENT supplied, three candidate positioning statements with the competitor test applied to each, and a channel plan sized to the team they actually have); the content engine (a pillar piece drafted from their own expert's interview, a repurposing matrix where no asset may introduce a claim the article does not carry, and a 30-day calendar with approval built in as a step); paid-ads copy (angles pulled from real customer language, platform-ready variants that vary one thing at a time, and a claims-and-policy check that runs before launch); email and lifecycle (welcome, nurture and win-back sequences, with consent, unsubscribe and approved offers on the review step); reporting and client communication (a monthly narrative written from THEIR export, an honest wins-and-misses framing that never buries a miss, next month's plan, and the version you send when results are below plan); and agency growth (proposals that open with the client's problem, a scope document a month-four disagreement can be settled by, the discount and cheaper-quote conversations, and a case study you may only build from real approved results). Every prompt that touches a number requires you to paste it in [brackets] with the platform and the date: this system never generates a metric, a benchmark, a market size or a forecast. The ads workflow forbids guaranteed-results and typical-results claims and includes a platform-policy review step; the case-study step will not write a figure you have not supplied. The closing page is the compliance pass — verify every claim against what the client put in writing, get their approval before publishing, leave contracts and regulated-category claims to the professional licensed to advise on them, and never paste client PII, customer lists or credentials into an AI tool.
