We are rolling out a change to the way placements work when specifying YouTube URLs. Starting on
August 14, 2018, using generic
placements to specify YouTube channels or videos is going to be disallowed and will result in an error.
For more accurate video targeting, even when videos are played across platforms, use the new specific
YouTubeChannel and
YouTubeVideo placement criteria when you want to target specific channels or videos in AdWords scripts.
If you have any questions about these changes or AdWords scripts in general, you can post them on our
developer forum.
