Updated July 2026.
Engage-through attribution is a Meta attribution bucket introduced March 3, 2026. It credits a conversion when someone engaged with (but did not click) an ad — for video, after a 5-second view — within a 1-day window.
What changed on March 3, 2026?
Two things. Click-through attribution now requires an actual link click, and Meta added the new 1-day engage-through bucket, lowering the video engagement threshold from 10 seconds to 5. One-day view-through attribution itself is unchanged.
What is the new default window?
| Bucket | Window |
|---|---|
| Click | 7-day |
| Engage-through | 1-day |
| View | 1-day |
