# MK-207｜New-Customer Hero Post Assessment

For a regular chat, upload `packs/mk-207.md`; it includes the shared rules, this method, and required references

## Purpose

This Skill delivers: **Performance and suitable audiences for new-customer acquisition**

Past success supports candidates and hypotheses only; shared content elements are not proven causes of success

## Required Inputs


Available raw records: Post ID results by new-customer audience, purchase-history mapping, spend, mature orders, offers, and cost objectives

## Method Steps

1. Separate each Post ID test in a new-customer audience and join actual first-purchase status, spend, mature orders, page, and offer. First-time visits do not establish first purchases; keep unknown purchase history separate
2. High CTR or cart adds support message response. Acquisition decisions require valid first purchases and their cost. Sales confined to existing buyers or warm lists support a warm-audience use instead
3. Keep a post in its original new-customer audience when mature results meet the cost objective. A comparable second new-customer audience, a valid promise, and available supply support a bounded test in similar new audiences
4. If removing the largest order reverses the cost or contribution decision, retain a capped test candidate. Spend or elapsed days alone do not establish adequate evidence. Without a cost objective, report observed costs and conditions rather than inventing a target
5. Remove orders reclassified as returning buyers and recalculate. Failure to replicate withdraws expansion into that audience while preserving supported original uses. Request the order record that changes identity or cost classification

## Calculation and Interpretation

First-purchase cost = test spend / confirmed valid first-time buyers; unknown identities stay outside the denominator. Deliver costs by audience, candidate scope, and expansion or withdrawal conditions

Check example (hypothetical): 3,000 spend and six confirmed first buyers yield 500 against a 600 limit, supporting the original audience. Three are later identified as returning buyers; cost becomes 1,000, withdrawing the acquisition-based expansion recommendation
