Google Ads / API Reference
gads_compare_ad_performance
Google Ads tool (extended/low-level coverage). For common tasks prefer the RECOMMENDED google_ads_* actions; use these only for advanced operations those don't cover. Compare performance metrics side-by-side for multiple ads over a date range. Returns conversion rate, CTR, CPA per ad.
This is a read-only tool: it compares ad performance from your Google Ads account. It changes nothing.
