US general store, feed-only PMax, 700+ products. Had good ROAS earlier this year, but lately it dropped โ I think a lot of my winners were seasonal and faded.
My old setup: one main PMax for testing โ when a product hit ~10 orders at good ROAS I moved it to a separate winners PMax. Then I saw Chris say never move products out of the campaign they perform in ๐
Questions:
1. Best structure for a general store โ main PMax + Standard Shopping booster for zombies/new products, or main PMax testing + separate winners PMax? And if winners get separated, do they stay in main too or get excluded?
2. New products barely get spend with 700 products in one PMax โ booster campaign, or trim the feed to proven sellers first?
3. Once stable, raise budget daily when above break-even, or 10โ20% every 3โ5 days?
Appreciate you guys ๐
