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. Claude identifies that 73% of the increase came from one ad set where frequency hit 4.2 and CTR dropped 31%. 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
• Recommended fixes for each factor in priority order
• Comparison data showing exactly what shifted between periods

When to use it

• CPA jumps more than 15-20% day over day or week over week
• Client asks "why did performance drop" and you need an answer fast
• Monday morning account checks when you need to catch weekend issues
• Before budget calls to identify and fix problems proactively
