Question 1

In a time decay attribution model, which touchpoints receive the most conversion credit?

Accepted Answer

Touchpoints closest in time to the conversion

Answer

The time decay model assigns exponentially more credit to touchpoints that occurred closer in time to the conversion, reflecting the assumption that recent interactions had the greatest influence.

Question 2

What does a position-based (U-shaped) attribution model assign credit to?

Accepted Answer

40% to first touch, 40% to last touch, 20% distributed among middle touchpoints

Answer

The position-based model gives 40% credit each to the first and last interactions (which initiate and close the sale) and distributes the remaining 20% among the touchpoints in between.

Question 3

Which attribution approach uses machine learning algorithms to calculate each channel's actual contribution to conversions?

Accepted Answer

Data-driven attribution

Answer

Data-driven attribution uses ML to analyze all conversion paths and assign fractional credit based on how much each touchpoint statistically contributed to conversions compared to paths that did not convert.

Question 4

Cross-device attribution is challenging in web analytics primarily because:

Accepted Answer

Users are often not logged in and cannot be matched across devices

Answer

Without a common identifier such as a logged-in user ID, it is difficult to stitch together sessions from different devices belonging to the same user into a single conversion path.

Question 5

An analyst wants to understand how email marketing assists conversions without being the final touchpoint. Which GA4 report or concept is most relevant?

Accepted Answer

Conversion paths / assisted conversions analysis

Answer

Assisted conversions (available via conversion paths analysis) show how many conversions each channel helped initiate or influence even when it was not the last click before conversion.
