Platform: Google and Meta. metadata: platform: Google and Meta --- # 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 ## Data access (Ryze MCP) This skill works best with live account data.

[{"step":"Identify the campaign and timeframe. Gather platform-specific data (e.g., Meta Ads Manager or Google Ads UI) for the period before and after the CPA spike.","tip":"Export raw data (e.g., cost, conversions, CPA, frequency, CTR) for the last 14 days to ensure accuracy. Use platform filters to isolate the campaign in question."},{"step":"Run the prompt template, replacing [PLACEHOLDERS] with your campaign name, platform, and time period. Include any additional context (e.g., recent creative changes or budget shifts).","tip":"For deeper analysis, add: 'Also compare performance against industry benchmarks for [INDUSTRY] in [REGION].' This helps contextualize the spike."},{"step":"Review the AI's breakdown of contributing factors. Cross-reference with your own notes (e.g., recent A/B tests, competitor launches) to validate findings.","tip":"Use the 'Top Contributing Factors' section to prioritize fixes. Focus on high-impact, low-effort changes first (e.g., pausing underperforming ad sets)."},{"step":"Implement the suggested actions in your ad platform. Set up alerts for key metrics (e.g., CPA, frequency) to catch future spikes early.","tip":"For Meta Ads, use the 'Advantage Campaign Budget' feature to auto-allocate budget away from underperforming ad sets. For Google Ads, adjust bids via 'Bid Simulator' before making changes."},{"step":"Monitor results daily for 3-5 days. Re-run the analysis if the CPA doesn’t improve to identify missed factors or new issues.","tip":"Use Google Sheets or Meta Ads' 'Custom Reports' to track metrics like CPA, CTR, and frequency over time. Set up automated alerts for CPA thresholds."}]
