Metrics

Your feed and prices decide what Smart Bidding can scale

ROAS

Revenue ÷ Ad spend

Merchant Center feeds power Shopping and Performance Max. Without margin signals — and without knowing where you sit vs market price — Google prefers high-revenue or discounted heroes that can destroy contribution margin.

POAS

Gross profit ÷ Ad spend

Profit Bid generates your Merchant Center XML feed, connects Price Insights for competitive gaps, and maps live POAS tiers to custom_label fields — exclude X products, prioritize A products, and keep Shopping spend on profitable inventory.

XML feed generation from your catalog for Merchant Center scheduled fetch.
Price Insights — see under / similar / over market gaps per SKU.
A/C/X labels refreshed from store order economics.
Pairs with Google Ads POAS conversion upload for a full loop.

Excluding X-label products from broad Shopping/PMax typically reallocates budget toward A-label margin winners.

Common questions

Do I need a new Merchant Center account?

No. Profit Bid generates an XML feed you fetch in your existing Merchant Center account, and Price Insights connects to the same GMC account.

What is Price Insights?

GMC Price Insights shows how your product prices compare to the market (under, similar, or over). Profit Bid pulls those signals so you can act on them.
