POAS & commercial bidding
How do I move from ROAS-based bidding to POAS-based bidding?
Why this matters
The transition from ROAS to POAS is more data work than bidding work. The Google Ads side is mostly already there: value rules, custom labels, tCPA and tROAS all exist. The blocker is usually that no one has cleanly assembled COGS, return rate and fulfilment per SKU in one place.
Step one: assemble the data. Pull COGS per SKU from your ecommerce platform or finance system, return rate from order data (rolling 90 or 180 day depending on category), and fulfilment cost per order. Land it in a single sheet or feed that the agency or in-house team can refresh.
Step two: tag commercial role on each SKU using custom labels. Scale, Profit, Protect, Recovery, Gateway. This is a commercial decision, not an algorithmic one. It needs the founder or commercial lead's input on which SKUs are doing what job.
Step three: feed margin into Google Ads. The cleanest path is value rules adjusting conversion value by SKU or category, supplemented by a profit feed where the platform supports it. This tells the bidder that two orders of equal revenue are not equal in commercial terms.
Step four: switch from a single blended tROAS to per-role tROAS targets. Allow two to four weeks for the bidder to retrain on the new signal. Expect short-term volatility: that is the algorithm finding the new equilibrium, not a problem.
How JudeLuxe approaches this
JudeLuxe runs this transition as a defined six-to-eight week sequence during onboarding. The data plumbing is the long pole; the bidding switch is days.
