Click-Through Rate (CTR)
CTR is the percentage of viewers who click a link after seeing it. It is a core health metric for creative quality, trust, and audience-message fit.
Why CTR is operationally important
Low CTR usually indicates weak positioning, poor message fit, or trust friction in the URL itself.
How link design affects CTR
Branded domains, descriptive slugs, and cleaner link presentation can materially improve click behavior in paid and organic channels.
