Attribution Windows Explained: Why Lookback Periods Change Results
An attribution window is the period during which a marketing interaction remains eligible to receive credit for a later conversion.
Short windows emphasize recent influence
A shorter lookback period is more likely to credit interactions close to the conversion.
Longer windows capture delayed decisions
Businesses with long consideration cycles may need a longer view to observe the role of earlier touchpoints.
Platforms can use different windows
If two systems look back over different periods, their conversion totals and channel credit can diverge even when both are functioning as designed.
Match the window to the buying cycle
The right window should reflect how long customers realistically take to convert, while remaining useful for the decision you are making.
