Google Ads ROAS is powerful for value-based optimization, but a target should come from your economics rather than from a universal benchmark.
Start with the economic floor
Calculate the ROAS where contribution profit covers ad spend. That breakeven value is the minimum useful reference point for target setting.
A higher target is not always better
Very aggressive target ROAS settings can restrict volume. The business goal is profitable growth, not the highest possible ROAS displayed in the interface.
Separate campaign roles
Brand search often has high ROAS because demand already exists. Non-brand search and Shopping may show lower ROAS while contributing more incremental customer acquisition.
Merchandising affects Google Ads
For Shopping and Performance Max, product titles, pricing, availability, imagery and landing pages all affect traffic quality and conversion performance.
Recalculate when costs change
If COGS, AOV, shipping or return rate changes materially, update the target rather than treating it as permanent.
Calculate your own break-even point
Use your real product costs, fees, returns and conversion rate instead of relying on generic targets.
