Difference between last interaction and last non direct interaction for google analytics


Would someone be able to explain the difference between last interaction and last non direct interaction on google analytics model comparison tool for me please?

See below image:

Last interaction - my understanding is that on a last click basis, there were 40 conversions attributed to direct via this model

Last Google Ads click - via this attribution method, 28 conversions were attributed. Meaning according to google ads 28 of those conversions were from adwords, but on last click basis 40 of those conversions were last click direct.

Last non-direct click - this is where I am getting stuck. As last non-direct ignores direct, I would think last non direct interaction would 0 for channel= direct?

Any insights would be appreciated!

Solution

  • If a user start a session from Organic and then makes another session as Direct, in the last click non direct model the conversion is attributed to the Organic, in the last interaction instead to the Direct one.

    If there are only direct sessions (one or more), the conversion is attributed to the Direct (because it's like it's the last click non direct unless there is only direct).
