First Interaction Attribution Model - What time range does this cover?
I know that under the First Interaction model, Google attributes 100% of the conversion value to the channel that provided the First Interaction.
However, my question is, what range is this?
For example, in First Interaction Model Attribution:
Day 1 - User visits my website via AdWords
Day 15 - User visits my website via Direct and makes a purchase of £100
First Interaction would attribute 100% of the sale to AdWords.
However, what about this?
Day 1 - User visits my website via organic Google Search
Day 150 - User visits my website via AdWords, and makes a purchase of £100
I'm guessing Google will attribute 100% of the sale to AdWords, as the User's organic Google Search visit was 150 days ago, and thus too far back.
That's my question: What defines a "first interaction"?
