A conversion occurring after a user clicks on an ad.

Why It Matters

Click-through conversions are the most reliable indicator of direct ad impact because the user took explicit action. CTC data is the foundation of performance marketing measurement and optimization, helping you evaluate true campaign effectiveness.

Practical Example

Scenario

A user clicks a Meta retargeting ad showing a product they viewed. They complete purchase 2 days later through email.

Result

Meta gets CTC credit if within the attribution window. This is more reliable attribution than view-through because the user explicitly engaged.

Pro Tips

  • 1Track CTC by device and time-to-convert to understand your customer's click-to-purchase journey
  • 2Compare CTC rates across audiences—cold traffic naturally has lower CTC than retargeting
  • 3Use CTC data to optimize bottom-of-funnel campaigns where direct response is the goal

Common Mistakes to Avoid

Only valuing CTC and ignoring view-through—this undervalues brand awareness efforts
Using very long CTC windows (28+ days) which dilute the signal-to-noise ratio

Frequently asked questions

7 days is the new standard after iOS14.5 (down from 28). Some platforms still offer 28-day, but shorter windows are generally more accurate.
