How to attribute CTV's role in the overall paid media mix
I'm working for a $20M ARR b2b SaaS and CTV is now 20-25% of our paid mix.
We're well past testing and are now trying to figure what role it should play in the ful paid mix as we scale. We’re seeing the expected signs: branded search lift, more direct/dark traffic, etc, but the signals are showing up downstream. Credit still collapses into last-touch search/direct, and as usual, each platform is overclaiming.
In a mix model, how do you judge CTV's contribution relative to lower-funnel channels and if any, what signals do you trust for when CTV is showing up indirectly?
