# Feed Labels That Survive Performance Max Experiments

Performance Max hides a lot of pathing, so feed hygiene becomes the control surface you still own. Label products by margin band, shipping constraint, and whether the landing page is fully localized. When a label drifts from the on-site locale, you get wasted spend that looks like creative failure.

Keep a changelog of feed attributes. Align GTINs and custom labels with the same taxonomy used in analytics. Exclude products that cannot ship to the campaign geo instead of relying on the algorithm to learn slowly.

PandaWM ties feed ops to multilingual site checks so ads and organic citations describe the same catalogue. Boring feeds beat clever sitelinks that point at the wrong language.

# Field notes

Keep screenshots dated. Prefer primary sources over sales decks.
