How to Set Up Your Feed for Maximum PMax Performance

The practical implementation guide: supplemental feeds, custom labels, and eliminating the "zombie products" draining your budget.

A supplemental feed lets you test optimized titles without touching your primary feed or website. This is the safest way to run title experiments following our optimization strategy .

Custom Labels (0-4) are your secret weapon for PMax segmentation. They let you group products for different bidding strategies within a single campaign.

Zombie products are items that receive impressions but almost no clicks. They waste budget and drag down your overall campaign performance.
