See POAS vs revenue-only reporting
Profit Bid connects store costs to ad spend so you bid on margin — not vanity ROAS.
Track POAS automatically from your store — upload profit conversions and scale winners with A/C/X labels.
The core difference
ROAS ignores costs beyond ad spend and uses revenue as the return. ROI accounts for all costs and uses profit. That is why they can point in opposite directions.
A campaign at 500% ROAS on a 15%-margin product may deliver a negative ROI once COGS, shipping, and fees are included.
Where POAS fits
ROI is the right lens for the business, but it is hard to compute per keyword. POAS brings profit to the ad level by dividing contribution margin by ad spend.
Optimize campaigns on POAS, then confirm the business-level ROI improved.

Is ROAS a type of ROI?
Not really. ROAS uses revenue and only ad spend; ROI uses profit and total investment. They are related but distinct.
Which should I optimize ads on?
Use POAS for ad decisions (profit per ad dollar) and track ROI at the business level to confirm real returns.
