Digital marketing term
Conversion Window
A Conversion Window is the setting that defines the maximum time after a user interacts with an ad during which a resulting conversion can still be attributed to that ad.
Detailed explanation
This period can be defined separately for click-through and view-through conversions; for example, a platform might use a 30-day click-through window alongside a 1-day view-through window.
The length of this window should vary with product price and purchase decision time; a short window is sufficient for low-priced, quick-decision products, while a longer window more accurately reflects true impact for higher-priced products.
Choosing this setting incorrectly can attribute conversions to the wrong channel and cause budget decisions to be based on flawed data.
