Target ROAS at 300%, consistently getting 400%
Posted by on September 5, 2025 at 9:12 pmI have a shopping campaign that consistently outperforms the target ROAS by a wide margin (target at 300% and has been averaging 400% over the last 12 months).
What am I missing out on by leaving it at a target of 300%?
I would like to see the campaign spend more than it currently does, so to me, raising it to 400% worries me that it will just decrease aggression.

Yup leave it there. I even drop my ROAS at the 2-level and get 4 or 5+
By lowering the ROAS you enter cheaper auctions to learn and win auctions with higher conversion value

If you want to spend more, you lower your ROAS down. If you increase it, Google could spend less.

Raising the target closer to 400% will restrict spend even more, lowering it below 300% will loosen the system to chase volume while still keeping returns strong.

If you want a higher ROAS, you raise the target.
But if you want to increase spend and get more total revenue, you need to lower the target. This tells Google it has more room to bid aggressively. Try dropping your target from 300% to 280%. Your ROAS will likely fall from 400% to around 350%, but your overall revenue should go up.

You’re leaving volume on the table by keeping the target too conservative. If you’re consistently hitting 400% ROAS, raising your target to 350-375% will likely increase spend while maintaining profitability above your actual breakeven point.
The algorithm is being overly cautious because your target is set too low… it’s finding the most efficient conversions but missing opportunities where you could still be profitable at higher CPCs.
For my shopping clients with similar performance gaps, gradual target increases typically unlock 20-30% more volume without significant efficiency loss. Start with small increments rather than jumping straight to 400%.
