Nope, and it can actually hurt you.
Many advertisers block YouTube or Display early because those placements “don’t convert directly.”
But here’s the catc, they feed awareness. PMax uses those signals to identify users who are researching before buying, which later improves your Search and Shopping conversions. Excluding them shrinks your learning pool.
Instead, monitor performance by asset group, not channel.
If YouTube seems wasteful, tweak your creative or audience signals, but don’t turn it off completely. Those top-of-funnel impressions might not bring immediate revenue, but they teach the system who not to target, which is just as valuable in the long run.
