About conversion tracking for YouTube
It's important to note that conversions in YouTube campaigns are counted differently than other types of line items in Display & Video 360.
YouTube & partners line items
Unlike other types of line items which require you to select a Floodlight activity to use for conversion counting, YouTube & partners line items automatically use any of the YouTube-enabled Floodlight activities that exist for your advertiser to count conversions. For information on enabling your Floodlight activities to count YouTube conversions, see Set up conversion tracking for YouTube inventory. View-through-conversion (VTC) reporting is not available for desktop but is supported for mobile.
TrueView video discovery ads attribute a conversion when the billable event (a view/click) is reached and a conversion occurs on the advertiser’s website.
