What is an Attribution Window?
An attribution window refers to the specific timeframe in which a conversion is linked to a marketing action, like a click, ad impression, or email open. When a user finalizes a conversion, such as making a purchase, during this period, the initial marketing touchpoint receives the credit.
It establishes the timeframe for which user actions are deemed significant to the ultimate conversion.

Why Attribution Windows Matter in Marketing
- They influence your evaluation of campaign effectiveness.
- Your calculations for return on ad spend (ROAS) are impacted by their influence.
- A limited timeframe might underestimate the importance of top-of-funnel channels.
- A prolonged window might exaggerate the impact of earlier interactions.
Your attribution window fundamentally influences your understanding of which campaigns yield results.

2. View-Through Window

3. Custom Windows
