Cost per retargetable member

Measures cold ad sets by what it costs to add one person to your retargeting audience: spend divided by the actions your retargeting pools are built from. Finds the ad type and objective that build the warm audience cheapest, and shows what each change you made did to the number.

Reads your data, changes nothing

What it does

It reads your exports. And changes nothing in your accounts.

You bring: The ad-level Ad Performance export for the last 30 days (daily rows if you want before-and-after readings), plus earlier months for a trend. How you mark stage and format in ad set names (for example S01 for cold, TLA-VID and TLA-SI for thought leader ads). The actions your retargeting audiences use per ad type, if different from the defaults. A list of dated changes: new creative, bid, budget, targeting. Optional: actual retargeting audience sizes and last run’s history table.

You get back: The data check, cost per retargetable member by ad type and objective, then by ad set and ad with its band and a volume check, where the cost is too high and the question to ask, the monthly trend, before and after each change, up to 8 recommendations, and a history table to paste into the next run.

The prompt

Paste it into your AI. Attach your exports first. It reads them and changes nothing
