Experiment eating Base?
I am running an experiment off my base campaign. The budget split is 50/50.
But, now after 2.5 weeks, the base is barely serving and the experiment is spending just fine.
The base campaign is a max conversjon with tCPA. The Experiment is a max conversions (no tCPA) and targets a conversion action lower down the funnel.
Has anyone run into this before? How can I get my base to actually serve impressions again.
Additonal Context:
- There is plenty of budget to spend. I can even increase the budget but none of my IS lost is due to budget (0%) for the base.
- I even increased my tCPA by 15% for a week on the base campaign to test and see if that gets it to serve. Nothing happened
- no other warnings, policy issues….etc
