What is Post-Citation CTR?

Not measured. It requires click data the AI platforms do not expose to third parties.

Post-Citation Click-Through Rate is the percentage of AI mentions or citations that lead a user to your digital property. It is the bridge between visibility measurement and attribution.

The IAB treats it as a bridge metric rather than a settled one, and notes availability depends entirely on the platform: not all AI platforms expose click data, so no measurement provider can synthesize it.
