YouTube Creator Partnerships analytics gained unique reach and co-viewer metrics for linked creator videos

The Analytics tab in YouTube Creator Partnerships now reports estimated unique reach, including co-viewers who watched together, using cross-device statistical models alongside views, watch time, likes, comments, shares and engagement rate. Unique reach can be calculated for up to 92 days and segmented by week or month, but not by day, quarter or year.

Google's help page says the reach models adjust for people who see the same video on multiple devices or who share one device, using methodology consistent with YouTube Analytics. First reported by Hana Kobzova via PPC News Feed; the Google Ads Help page carries no publication date.
