Incremental performance
Hey everyone ?
Wanted to ask how you go about calculating the incremental impact of your campaigns on different google channels: search, display, video, etc.
Do you run control hold out versus variant tests? Do you do it by audience?
Right now I’m struggling with figuring out how to start calculate incremental ROAS on channels and campaigns to optimize better. I feel I am spending my budget on users who may not be worth it (returning users and therefore cannibilisation and no incrementality).
Would love to hear from more experienced folks on how they set this up or go about evaluating incremental impact of their work.
