Why Performance Max matters
For ecommerce it absorbed Shopping’s role and became the default Google engine: the feed does the product work, assets do the creative work, and tROAS steers delivery across every surface Google owns. The trade is the Advantage+ trade with a Google accent: reach and automation for control and visibility, and the buyer’s craft moved to feed quality, asset variety, and auditing what the black box claims.

Questions
Does PMax just take credit for brand and retargeting demand?
It will if allowed: left open, delivery gravitates to the easiest conversions, brand searches and warm audiences, and reports them as performance. Brand exclusions, new-customer goals where offered, and incrementality checks separate what it created from what it collected.
Feed-only or full-asset PMax for a store?
Feed-only behaves closest to classic Shopping, concentrating delivery on product surfaces; full assets unlock the wider network with creative doing more of the work. Start where your evidence is, a strong feed, then add assets deliberately and watch where the extra spend actually lands.
