Why Click-Through Rate matters for Google Ads users
CTR is the bridge between visibility and engagement in paid search. A low CTR means your ads are being shown but not resonating - wasting impressions and potentially lowering quality score, which increases costs. A high CTR indicates strong ad-keyword-audience alignment.
Positioning CTR in your metric tree between impression metrics and conversion metrics reveals whether engagement or conversion is the bottleneck in your paid funnel. Statistical correlations show how CTR changes cascade through to cost per acquisition and revenue.
