Keyword Spends Change Using Google Ads MCP with Claude

Analyze Google Ads account data for drastic changes in keyword-level spends within campaigns over the last 30 days, compared to the previous 30-day period. Identify keywords with large increases or decreases in spend, and for top performing campaigns/adgroups, also check for drastic changes in keyword-level conversions. For each keyword with significant shifts, report monthly spend and results for “top last month” vs “top this month,” including bottom-performing keywords for both periods. Clearly show comparison tables for all metrics available (spend, impressions, clicks, conversions, CPC, CPL, etc.). Validate all data points directly from the platform. Disclose and explain any unavailable metrics or missing data due to system limitations. If data sets are too large, chunk the analysis and aggregate for final reporting. Support every finding and hypothesis with direct data and clear logic. Conclude the analysis with a concise prioritized summary of main findings and actionable next steps to improve keyword performance and account results.
