AI Prompts for Marketing Agencies

Getting started with AI for your agency

You don't need a strategy deck or a new tech stack to start. You need one repetitive task, one good prompt, and two weeks of consistency. Here's a simple 30-day plan to go from "we should try AI" to AI being part of how your agency works.

The plan in one line: Week 1, one person automates one task. Week 2, they build a shared "house prompt" for it. Week 3, the team adopts it and starts a shared prompt library. Week 4, you decide what's worth connecting to your real tools. Small, real, compounding — not a big-bang rollout.

Before you start: three ground rules

The 30-day plan

Week 1

One person, one task

Pick the single most repetitive writing task in your week. For most agencies that's turning meeting notes into actions, or metrics into a report narrative. Have one person run it through AI every time it comes up, using a prompt from the library. The goal isn't scale yet — it's to feel the time saved and learn where the AI needs steering.

Start here Turn these meeting notes into (1) an owner-tagged action list and (2) a 3-line recap I can send to [client]. Flag anything that sounded like a decision but wasn't confirmed. Notes: [paste notes]
Week 2

Build your "house prompt"

A generic prompt gives generic output. Now bake in your agency's standards: your tone, your report structure, your definition of done. Save this improved version somewhere shared. This "house prompt" is what makes AI sound like your agency instead of everyone else's.

Make it yours Take the base prompt you've been using and add: our house tone ("[describe]"), our standard section order, and our rule that no numbers or claims appear unless they're in the source material. Show me the upgraded prompt I can save as our team standard.
Week 3

Roll it out and start a prompt library

Share the house prompt with the wider team and add a second task. Create a simple shared document — your agency prompt library — where anyone can drop a prompt that worked. This is how AI use spreads without a mandate: people copy what already works for their colleagues.

Week 4

Decide what to connect

By now you'll notice the friction: copy-pasting notes, exporting metrics, hunting through email threads. That copy-paste is admin. The next level is AI connected to the tools where your work already lives, so it drafts from live data with no pasting. Decide which one or two workflows are worth that investment — usually reporting and client updates, because they're frequent and structured.


Common mistakes to avoid

Where this leads

Agencies that stick with this end up in one of two places. Some are happy with a strong shared prompt library and a team that uses AI fluently in a chat tool — that's a genuinely good outcome. Others hit the ceiling of copy-paste and want AI wired into their actual systems, drafting reports and updates from live data automatically. That second step is a build, and it's where an implementation partner earns their keep.

When you're ready for connected AI

SG1 Consulting builds AI into the tools your agency already runs on — so the reporting, status updates and follow-ups draft themselves from live data instead of copy-paste. When your team has outgrown the chat window, that's the next step, and it's what they do.
