Attribution model for both Display and Video campaigns
If I am running both display and video campaigns to the same location, how would the attribution work for the following scenarios?
1. Tom views the YouTube ad, 3 days later clicks on the banner ad, then makes a purchase.
2. Mary clicks on the banner ad, 3 days later sees an impression of the YouTube ad (less than 30 sec), then makes a purchase.
I would like to know how conversions and/or view through conversions work in these cases. Also I want to know if there is a way for Adwords to attribute conversions to both display and video in these two cases.
