What it does
Ads to people who already bought are the easiest place to overspend. Meta credits these buyers with sales they might have made anyway, so the numbers look great while the money buys little new growth. Many audits find past buyers seeing 20 to 100 ads in 30 days. About 10 is reasonable. This skill sizes the budget in dollars, not as a share of spend, because a percentage moves every time your new-customer spend moves. The formula is customers x target monthly frequency x CPM / 1,000. It then sets a lower CPA ceiling than for new buyers, plans a test where you cut spend about 30 percent and watch sales, and proposes a proper lift test. It treats retargeting as a capped support layer and bends the advice for categories like fashion, where past buyers do come back.
You give it
- How many existing customers are synced to Meta
- Your CPM on existing customers, from the audience segment breakdown
- Target and current monthly frequency
- Current daily spend and sales on existing customers
- Your category and how long buyers take to reorder
- Brand brain (optional)
You get
- A monthly dollar cap
- A frequency check and what to cut
- A CPA ceiling for existing customers
- A spend-cut and lift test setup, and the money freed for new customers
Use it when
- Your reports show strong ROAS and you suspect past buyers are flattering it.
- A large share of your Meta spend goes to retargeting or existing customers.
- You have a customer list of a few thousand buyers or more and don't know what to spend on it.
How to use it
- Start a chat with the skill. Open it if you added it to your AI, or copy it and paste it in.
- Turn on audience segment reporting in your Meta advertiser settings, then paste your customer list size, existing-customer CPM, frequency and spend.
- Say what you sell and how long buyers usually wait before they reorder.
- Set the cap it gives you as a ceiling and run the 30 percent cut test for a week or more.
- Run a conversion lift test on the existing-customer campaign for 30 days to prove the number.
