Given your total budget, recommends the optimal split across Google Search, PMax, Meta prospecting, Meta retargeting, and any other active channels based on your last 60-90 days of marginal ROAS and CPA by channel. Tells you where each additional dollar produces the best return. Platform: Google and Meta.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# 15/ Channel Mix Optimizer — Google + Meta ## What it does Given your total budget, recommends the optimal split across Google Search, PMax, Meta prospecting, Meta retargeting, and any other active channels based on your last 60-90 days of marginal ROAS and CPA by channel. Tells you where each additional dollar produces the best return. ## How it works Claude calculates marginal efficiency for each channel — not average ROAS (which hides diminishing returns), but what your last dollar spent in each channel actually returned. It builds an efficiency curve per channel and recommends the allocation that maximizes total conversions or revenue within your budget constraint. ## Practical example You're spending $80K/month split evenly across 4 channels: Google Search ($20K), PMax ($20K), Meta prospecting ($20K), Meta retargeting ($20K). Claude's analysis shows Google Search still has headroom with marginal CPA at $34, Meta retargeting is maxed out with marginal CPA at $72 (the audience pool is exhausted), and PMax has middling marginal returns. Recommended reallocation: Google Search $32K, PMax $18K, Meta prospecting $22K, Meta retargeting $8K. Projected result: 23% more conversions …

How to install
mdr add irinabuht12-oss/marketing-skills/channel-mix-optimizer@sha256:c4e1ce1059495670The line at the top of this page pins the label git:20261027.b3bdcd6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
