When your CPA spikes, Claude breaks down exactly what caused it. It looks across your campaign data and isolates the contributing factors — audience fatigue, bid landscape shifts, creative decay, landing page conversion drops, budget distribution changes, or new competitor activity. 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.

# 1/ CPA Diagnostics — Google + Meta ## What it does When your CPA spikes, Claude breaks down exactly what caused it. It looks across your campaign data and isolates the contributing factors — audience fatigue, bid landscape shifts, creative decay, landing page conversion drops, budget distribution changes, or new competitor activity. ## How it works Feed Claude your campaign data for the current period vs the previous period. It compares metrics at every level — campaign, ad set, ad, keyword, audience, placement — and identifies where the variance is coming from. Results are ranked by impact so you know what to fix first. ## Practical example CPA went from $42 to $67 overnight.

Another 18% came from a search campaign where a broad match keyword started matching irrelevant queries. The remaining 9% was a landing page with slower load time after a site update. ## What you get back - Ranked list of factors driving the CPA change with percentage contribution - Specific campaigns, ad sets, keywords, or audiences causing the issue …

How to install
mdr add irinabuht12-oss/marketing-skills/cpa-diagnostics@sha256:2350c50a79a32d46The 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.
