YouTube’s co-viewing metric may raise CTV reach on paper
This article discusses the inadequacy of current CTV metrics in accounting for co-viewing, suggesting that failing to do so distorts media pricing and undervalues the actual audience reached by CTV campaigns.
Key Takeaways
- Current CTV metrics often fail to account for co-viewing.
- Ignoring co-viewing can distort media pricing for CTV campaigns.
- The new YouTube CTV metric would count audience beyond a single viewer.
- Brands may see higher delivered reach from the same CTV inventory when co-viewing is measured.

YouTube’s metric directly targets that gap, which matters because CTV buying and reporting still depend on how reach is counted. The article’s core signal is the measurement method itself: whether co-viewing is included in CTV reporting will affect how buyers compare campaigns. Watch for whether more ad measurement systems begin reporting co-viewing alongside standard CTV impressions.
