Target ROAS (tROAS)
Target ROAS (tROAS) explained — Google's automated bidding to a return-on-ad-spend goal, common in 2026 e-commerce.
A Smart Bidding strategy where you set a target return on ad spend and Google bids to maximize conversion value at that efficiency level.
Formula
Bids optimized toward: Revenue ÷ Ad Spend = your Target ROAS
Benchmark range
Set tROAS to your break-even ROAS plus desired margin. E-commerce Google ROAS averaged ~3.68x in 2026, so targets are typically set around or above that.
Why it matters
tROAS optimizes for value rather than volume, ideal when products have varying margins. It requires accurate conversion-value tracking — wrong values produce wrong bids.
2026 update
With Google e-commerce ROAS down ~10% YoY in 2026 amid rising CPMs, advertisers are pairing tROAS with first-party value signals and MER tracking. Inside Performance Max, tROAS is the main efficiency lever you still control — feed accurate margin-based values, not flat revenue.
