Google tests channel prioritization controls for Performance Max campaigns
Google is experimenting with new controls that let Performance Max advertisers guide which channels the algorithm emphasizes. This moves toward greater transparency and advertiser agency over traditionally opaque automated bidding.
My take
- Google is testing channel prioritization settings within Performance Max, giving advertisers more say in how the algorithm distributes budget
- This addresses a longstanding advertiser complaint: Performance Max's black-box behavior and inability to steer away from underperforming channels
- The test suggests Google may be listening to feedback about algorithmic transparency and control
If this rolls out, check your Performance Max settings for new channel weighting options and test them against your best-performing channels. The full piece is worth the read — source link below.
