What does this setup do?

Use AI to draft Facebook ad angles, copy and a weekly test plan, then launch and control spend yourself in Ads Manager with a spending limit.

Who is it for?

Small businesses who want Facebook ads to work but do not want a bot spending money on its own.

How do you set it up?

Tools

  • ChatGPT, Claude or Grok Bot
  • Meta Ads Manager
  • 10 real customer reviews or messages

Steps

  1. Set an account spending limit in Ads Manager first. Meta says you set your ad account spending limit, and ads pause when it is reached.
  2. Paste 10 real reviews or customer messages into the prompt below to get 3 angles in your customers' words.
  3. Pick 2 angles and launch them yourself as a small test.
  4. After 7 days, paste the Ads Manager results into the same chat and ask what to keep, cut or change.
  5. Make changes yourself. Do not give an agent your ad account login.
  6. Keep a one-line log per week: angle, spend, result.

Example output

Illustrative. Your results will differ.

  • Angle 1: 'Showed up when they said' (quoted from 4 reviews)
  • Headline: On time, every time
  • Week 1: Angle 1 $35, 6 messages; Angle 2 $35, 1 message. Keep 1, replace 2.

Common questions

Can AI run my Facebook ads?
Let it draft angles, copy and the test plan. Launch and control spend yourself in Ads Manager with a spending limit.
How do I stop overspending?
Set an ad account spending limit in Ads Manager before launching. Ads pause when it is reached.
How long should I test an ad?
About a week before deciding, unless something is clearly wrong.

What tips make it smoother?

  • Customers' own words make the strongest angles.
  • Test 2 angles at a time, not 10.
  • Results after 2 days are noise; wait the full week.
